Shortcuts appearing when using Option+arrow in Outlook on Chrome in Mac
luse Outlook on Chrome in my MacBook Pro. While typing an email, though, if I use Option tarrow left or right (to go back or forth between words), after a few words, the shortcut letters for the menus pop up, and stop what I'm doing. (See image.) It doesn't happen in any other window on Chrome. So it's not a Chrome thing. It's only when Outlook 365 is loaded. (Don't know if it happens in other 365 apps, as I only use Outlook, really.) Anyone experienced that? And, if so, is there a solution? I tried Outlook 365's setting, but nothing there. Thanks!
Login not possible
Since the beginning of the year, I have had the problem that I cannot log into my email account via Outlook. I have contacted Microsoft support several times, and they have repeatedly told me to contact Outlook support directly, but I am unable to do so. I have already cleared my cache several times and tried using other browsers. I have also tried incognito modes, as well as using my cell phone. Whenever I try to log in, I get the following error message: That's why I hope that someone here can help me somehow.

Outlook for the web - some tenants not showing reply/forwarded icons in message list
Hi, (Outlook for the web) I wondered if anyone has experienced this and knows of any way to resolve it. One of my users is reporting that (and I have seen it) new replies are not being "flagged" with the reply icon in the message list. This appears to happen regardless of whether the email is in the inbox or a subfolder. Older emails (that have been replied-to or forwarded prior to today) are showing the relevant icons to indicate that a reply has been sent and it only appears to be affecting new replies/forwards. I've been through all the view settings in and nothing helps. I even tried crazy things like changing themes. This doesn't appear to be consistent across tenants either. I've seen 1 tenant with it working and another with it not working. Regards, PaulUnable to send emails to outlook
Hi, I would like to seek help with email delivery to outlook. it's been 2 months now since we encountered the issue - unable to send to outlook. We are receiving NDR from outlook. Moreover, we have our own mail exchange server.

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.

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?
