Sync Issues with Tracking Meetings from Outlook to Dynamics 365
Hello, my work uses the Dynamic 365 App for Outlook to track meetings as appointments in Dynamics 365, but it has failed several times for several users (on both Mac and Windows, in Old and New Outlook and on web browsers); some meetings will fail to track immediately while in some cases, meetings that were successfully tracked will stopped working and are no longer tracked in Dynamics. In the spoiler below is a sanitized version of the diagnostic log for meetings that used to be tracked that stopped working: In the log, we have the following error message: "lastsyncerror": "ExchangeSyncGeneralCrmItemSyncError;Microsoft.Crm.Asynchronous.EmailConnector.ErrorSource.Crm:130;T:188\r\nActivityId: [Removed]\r\n>Exception : Microsoft.Crm.Asynchronous.EmailConnector.ExchangeSyncException: Failed to sync item to CRM server : System.ServiceModel.FaultException`1[Microsoft.Xrm.Sdk.OrganizationServiceFault]: There is no active transaction. This error is usually caused by custom plug-ins that ignore errors from service calls and continue processing. at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) +0x27 at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) +0x1ba at Microsoft.Xrm.Sdk.IOrganizationService.Execute(OrganizationRequest request) at Microsoft.Xrm.Sdk.WebServiceClient.WebProxyClient`1.ExecuteAction[TResult](Func`1 action) +0x15 at CrmSDKLib.OrganizationServiceWrapper.<>c__DisplayClass10_0.<Execute>b__0() in C:\\__w\\1\\s\\src\\lib\\CrmSDK\\OrganizationServiceWrapper.cs:line 13..." In Outlook, when I look at these meetings and check the app it gives the message: Recurring appointment occurrence cannot be tracked However, we have other series of recurring meetings that have been successfully tracked that does not run into the issue. Anyone has encountered this or similar issue? How do we resolve this so going forward the app can track all meetings without issue? Please let me know, thank you!
Major journal's email does not pass Microsofts arbitrary standards nothing I can do about this

Look at all the people that were hospitalized from eating laundry detergent, clearly laundry detergent needs to be baned.Flagged Emails in New Outlook: Set Reminders and Due Date
I understand that transitioning from Classic Outlook to New Outlook can be intimidating and frustrating, especially regarding the feature changes. I'm here to help you navigate through the differences and make the switch as smooth as possible. You can access your flagged emails via the MyDay icon located in the top menu. Here are the steps to set reminders, due dates, and more. 1) Select the My Day icon 2) Click on the To-Do Tab (Note: Usually, this tab defaults to 'Tasks' for the primary mail account.) 3) If you manage multiple accounts, choose the correct mail account. 4) Select Flagged Emails: All flagged items for the select account will appear here 5) Right-click on any flagged item, and you will see many settings, including Set Reminder and Set Due date. I understand that completing the requirement involves many steps. It can be challenging, but I expect more improvements in the future. I hope this helps. /Teresa #traccreations4e 01/18/2024
Not receiving emails from a specific email address suddenly
All of a sudden on 1/23/26 I stopped receiving emails from one specific email address. I checked my spam folder, made sure there were not rules associated with this particular email address, made sure the address was not blocked, and even added the email address as a safe sender but as of today I am still not getting the emails. Another person who is put on these emails when they are sent to me as well is having no issues and is still receiving them no problem. Not sure why this is happening all of a sudden or if there are any other settings I can check? I read that outlook was down last week and people were having issues not receiving emails but I believe this has since been resolved.
MS Mail servers claim Hotmail domain does not exist
In my Gmail account I have a rule that forwards everything to my Hotmail/Outlook account where I primarily read all of my mail. This has worked well for a long time until the 16th January 2026 when I started to realise I was missing a few mails. Looking in the Gmail inbox I could see a few NDRs from Googlemail saying that it had failed to forward a message. I'm assuming this is an issue at the Microsoft end as the NDRs say it is a remote (i.e. Microsoft) mail server claiming that the domain Hotmail.co.uk doesn't exist, so the mail gets bounced. BTW, this is not an issue with my individual account, my wife and I have similar setups (both our Gmails forward to our Hotmails) and we both started having the same issue from that date. The key NDR details are always of this form: Address not found Your message wasn't delivered to ***@hotmail.co.uk because the domain hotmail.co.uk couldn't be found. Check for typos or unnecessary spaces and try again. The response from the remote server was: 501 5.5.4 Invalid domain name [AM4PEPF00027A67.eurprd04.prod.outlook.com 2026-01-20T22:06:56.421Z 08DE543D7B61AE38] So, it looks like some server in the chain is claiming that the whole domain "hotmail.co.uk" cannot be found!!! Surely I can't be the only one with this issue? I guess many people will be unaware they're missing mails as the original senders will be the ones receiving the NDRs, and where that is a company (rather than an individual) they probably just bin them and never investigate. This seemed to get worse over a few days and then stabilise to ~25% of mails failing: 16th Jan - 3 of 31 emails had this issue 17th Jan - 0 of 19 failed 18th Jan - 3 of 16 emails had this issue 19th Jan - 1 of 34 emails had this issue 20th Jan - 5 of 27 emails had this issue 21st Jan - 10 of 34 emails had this issue 22nd Jan - 8 of 31 emails had this issue 23rd Jan - 8 of 28 emails had this issue The issue seems to be random, there is no pattern with the times of day or senders - sometimes a particular sender is fine (e.g. Netflix, eBay), sometimes they suffer this issue. In the NDRs I'm not sure what the naming convention of the Outlook servers is but re. the above example's "AM4PEPF00027A67.eurprd04.prod.outlook.com", I've looked at all the servers mentioned in each NDR (up to 22nd) and again there's no real pattern - the hostname's always begin with either AMS0, AMS1, AM3, AM4, DB1, DB3, DB5, DU2, DU6, with the 4 character ones being followed by "EPF000xxxxx" and the 3 character ones being followed by "PEPF000xxxxx". The following subdomain is always eurprd02-eurprd05 with just two examples using EURPRD83. I did try and report to Outlook.com but their online help system currently gives an error (Error 500.30 - ASP.NET Core app failed to start). I hope this is a better place where someone might have a chance of convincing someone that there is a mail server config error somewhere?Outlook changing styles/colors of incoming email?
HI friends - I recently got an email from a research org named ORCid and I noted when I received the email that it was hard to read - the text was a lightt grey on white, or light grey on dark grey in dark mode: I emailed ORCid back and explained that this was going to fail any WCAG/Accessibility checks, and could they take a look. I spoke back and forth with their internal developer who insisted that it didnt look like that on being sent - he sent me examples from his own inbox as proof: And these look perfectly fine. Weirdly - when I forwarded this email to a colleague, they showed me on their screen it appeared as intended with the tetxt darker and more legible. They forwarded it back to me - and surely enough, it looks correct. This using the Outlook desktop app in both old and new mode - and dark or light profile - and also in the web outlook as well. Im really confused as to how/why when I receive it the first time it looks so unreadable? Any advice would be awesome.Organizing email account folders on PC
Since updating to the new Outlook, I am not able (on my PC or Mac) to drag and drop account folders to arrange them in a priority fashion. I have downloaded the classic version again, but the new version opens up anyway. I have tried on the app AND using a browser. Any help is GREATLY appreciated. I don't know if I am just not doing something correctly, or if that function is not available, except on my mobile devices. TYIA
Cannot unlock my Microsoft account, SMS verification not working
Hi, I need help with a blocked Microsoft account. When I try to sign in, the system asks for my phone number to unblock the account. The first SMS took too long to arrive and when I tried again I received an error message and cannot retry. I tried another phone number but I did not receive any SMS and now I cannot use my original number again. I tried all support options through https://support.microsoft.com/home/contact . I changed my password twice, completed the account recovery form, changed the password again, cleared cache, switched networks, changed browsers and used incognito mode. Nothing worked. When I enter my main number, it shows “Something went wrong” and does not go to the next step. When I use another number, I receive the “Try another verification method” error, even though no other method is available. My account is still logged in on my phone, but I cannot unlock it on the web or on other devices. I have had this account for more than 10 years and everything is linked to it. I even created another email to contact Microsoft Support, but it always redirects me to the same link and I cannot open an actual support ticket. Could someone from Microsoft please help me unblock my account or escalate this issue? I can provide any additional verification if needed. Thank you.Embracing the future: Transitioning to new Outlook for Windows
As technology moves forward, so do the ways we communicate. The world is rapidly changing with cloud computing, hybrid ways of working, and generative AI. To keep up with all these changes, Outlook is getting a makeover too. The updated Outlook for Windows is built to meet the needs of modern email and time management, with agility, consistency, and manageability. Since I last connected with you in November 2024, Outlook for Windows has evolved rapidly - delivering dozens more capabilities from classic Outlook, key improvements for Shared Mailbox, Offline and PST, and many new experiences to enhance productivity. This update shares examples and details on how Outlook for Windows is: Agile: Built to be responsive to your emerging needs Consistent: Streamlined across Windows and web Manageable for IT: Faster resolutions with less effort Agility: Built to be responsive to your emerging needs Every month you will see us deliver top requested capabilities from classic Outlook, new Copilot innovation, and improved stability and performance. Outlook for Windows is packed with capabilities designed to boost your productivity and make your day-to-day tasks easier. Innovation built in Outlook for Windows' new agile codebase has made it easier for stability, performance and security by design. We deliver features that were never implemented in classic Outlook. Now, you can enjoy top-requested features in Outlook like pinning important emails, tabbed search to find people, files and Teams messages more easily, iCal sync, scheduled mail, new themes and colored mailbox folders, and more. We've updated meeting experiences to support hybrid and global participation with capabilities such as support for up to 21 time zones and hybrid RSVP, sorting and search for tracking attendees, and the ability to follow meetings to be aware of what happened without needing to attend. These new time management features are ideal for our most dedicated users, including delegates. New shared mailbox capabilities We heard you! One of the top experiences we are improving is working with shared mailbox experiences. Outlook for Windows blends classic Outlook capabilities for shared mailboxes with new capabilities to address your long-standing needs. You can now add shared mailboxes as accounts alongside shared folders. With the new “Shared with me” page you can now view permissions on shared folders or mailboxes to identify and resolve access issues. You can control how the shared mailboxes and folders will be displayed in the Folder pane. The Folder pane also gives a clear visual distinction to shared mailboxes compared to dedicated email accounts, making them easy to access and use throughout your day. More functionality is coming soon, including Archives in shared mailboxes and more (available in Targeted Release and coming to Standard Release in July). Copilot agility For those aiming to maximize productivity with Copilot, we are adding Copilot features into Outlook every month. With Outlook for Windows' agile codebase, you will find the latest Copilot enhancements first, including the Chat side pane, Summarize, Drafts, Schedule from email, and more. Commercial users will value the new “Prioritize my Inbox” that helps users stay on top of their highest priority mail (rolling out gradually). Prioritize capabilities in Outlook for Windows and web Newsletters Communications through Outlook continue to evolve to meet user needs. The new Outlook Newsletters experience lets you quickly and easily create and send structured, professional, and richly formatted internal email newsletters within Outlook. This capability helps you keep your team informed and engaged. Each newsletter acts as a home for subsequent editions, making it easy to browse past issues and view aggregated analytics across the series. Readers can discover and subscribe to newsletters shared within your organization to stay informed on key topics and projects. While in Public Preview, admins can enable it for some or all users in an organization, and General Availability will follow in a few months. Newsletters are coming to Outlook for Windows and web first, and we plan to bring them to other Outlook clients. Copilot support for Newsletters is on the way, unlocking new ways to create clear and compelling communications with ease. Newsletters in Outlook for Windows and web Consistency: Streamlined across Windows and web The updated Outlook for Windows is all about delivering modern and comprehensive communications and time management experiences. We continue to balance delivering more of your favorite capabilities available in classic Outlook and innovation to meet your needs based on your feedback and requests. In-app feedback and upvoting are key to helping us prioritize what to work on next. For instance, Offline and PST support are top requests, and we have a stream of capabilities rolling out for these critical features, shown below. Offline capabilities Outlook for Windows already supports core offline capabilities to read and compose emails and boot while offline. Here’s a look at the latest Offline capabilities including Search (available now), attachments, event creation, updates, deletion, and RSVP (rolling out). Search email: Open an attachment: Create and delete an event: PST capabilities For users who store their content in PST mailboxes, we have many recent improvements to share. Now Outlook for Windows supports reply and forwarding emails in the PST, adding PST folders to Favorites, and dragging and dropping emails from the PST to the mailbox (or vice versa). The ability to export an entire mailbox or set of folders to a PST is now in Targeted Release. Importing from a PST, auto-export (aka auto-archive), people details in Profile cards, and support for read-only Calendar is coming later this year. Integrations across Windows and Microsoft 365 Outlook is deeply integrated with the Windows operating system to bring functionality that users expect of a rich, native app. This includes opening attachments in the native default app users choose, dragging and dropping attachments to the desktop, windowing, notifications, and more. Outlook for Windows is also seamlessly integrated with Microsoft Teams, without the need to install a separate add-in. More seamless switching across devices Outlook users are constantly on the move, switching between different devices and contexts throughout their day. When you add a new device, you do not need to reconfigure your settings. This focus on consistency is something our commercial customers have been asking for, and we're excited about delivering it. Plus, thanks to the common codebase, web users also enjoy most of the innovations and classic capabilities arriving in Outlook for Windows. Manageability: Faster resolutions with less effort For IT admins, Outlook for Windows deploys updates similarly to Outlook for web and Microsoft Teams, offering service-backed delivery that ensures predictable changes with Targeted Release and roadmap notifications. This means less time spent on build management. Plus, with changes delivered as a service, you should see a reduction in deployment costs. Both Outlook for Windows and web use Mailbox policies to manage the client experience. These policies help standardize settings, like attachment settings, for specific groups of users. This means users have a more consistent experience across platforms, as the policies are applied to a user's mailbox. IT admins can learn more about which policies from classic Outlook map to Outlook for Windows policies here and review the new security whitepaper here. Admins have a growing set of documentation in learn.microsoft.com and adoption.microsoft.com. We're making sure the transition to Outlook for Windows is as smooth as possible with migration aids such as the admin-controlled migration policy and you can now track new and classic Outlook usage in either the M365 or Exchange Admin Centers. M365 Admin Center with Outlook for Windows and classic Outlook usage reporting Transition to new Outlook for Windows The transition to Outlook for Windows is intended to be gradual, allowing you ample time to explore and become comfortable with its new capabilities. We recommend using the toggle in classic Outlook to try the updated Outlook for Windows experience. This will copy your settings, forward your protocols, and provide a welcoming experience. If you encounter a situation where the new Outlook experience lacks a critical function for your workflow, you can easily toggle back to classic Outlook. Don’t forget to provide feedback to let us know what’s missing. A great way to facilitate the transition is to run Outlook for Windows side-by-side with classic Outlook. However, we encourage you to spend as much time as possible working in the updated Outlook experience. This will help you fully experience its enhanced capabilities and discover new, efficient ways of communicating. Thousands of organizations have started migration with pilots and are working towards full-scale migration. Many organizations have already migrated, including some very large-scale organizations already surpassing 50% migration to Outlook for Windows. For more details on the timeline: New Outlook: Guide to product availability | Microsoft Learn What’s next? We continue to bring more classic capabilities and innovation every month. We encourage you to try the updated Outlook for Windows experience. If a needed capability is missing, let us know. To submit your feedback, go to the Help tab and select Feedback.
