Email sent from Shared Mailbox gets stuck in Outbox
Hello, I am working with a client who has a primary and shared mailbox in Outlook. They are using the newest version of classic Outlook desktop app and they have full permissions to the shared mailbox, including "send as" permissions. They can send email from their primary mailbox without issue. However, when they send email as the shared mailbox, it gets stuck in the Outbox and never sends. I have tried the following: 1. Removing the profiles re-adding 2. Deleting the Outlook data files 3. Reducing cache to as low as 3 months 4. Turning off cache but when I do the shared mailbox gets an error that it cannot connect to the Exchange server 5. Turning on auto-archive to shrink the data files 6. Switching to "New Outlook". This does seem to work but the company uses a plug-in for a program called "Mail Manager" and they don't fully support New Outlook yet Sometimes these solutions will fix the issue for a few days to a week but then it begins happening again. This issue does not happen when they are using the mobile or web clients. To me this sounds like a corrupted data file but I can't pinpoint what exactly is causing the corruption. Any suggestions? Thanks, Mike
Sync New Outlook with iCloud Calendar
I just got a new laptop and am trying to sync the New Outlook Calendar with my iCloud Calendar. The intent is to have any Calendar changes made on one device (iPad, iPhone, laptop) to sync to all device Calendars. The problem I'm having is that iCloud Calendar only synchs with Outlook (Classic) and I want to sync with New Outlook. The Outlook version is 1.2025.1121.100 ; the Outlook Client Version is 20251128003.09 The list of Apps that comes up after clicking on Start shows both Outlook and Outlook (Classic). If I right click on Outlook (Classic) and click on uninstall (thought that might help fix this), the only Outlook listed in Apps > Installed Apps is Outlook. I did not uninstall Outlook. To set-up Calendar synching I opened iCloud > Calendars and Contacts > Calendars and Contacts Settings. I turned on "Automatically sync your iCloud calendars and contacts to Microsoft Outlook". After syncing completes, all iCloud Calendar entries appear in the Outlook (Classic) Calendar, but nothing syncs to the New Outlook calendar. I'm assuming this is an Outlook issue, not an iCloud issue. Any ideas on how to fix this? Thanks
Synchronization issue in New Outlook for Mac – ״Failed to refresh subscriptions.״
Hello, I am using Microsoft 365 (Exchange Online) on Mac, running macOS 26.1 (Tahoe). My Outlook client is: Outlook for Mac Version 16.103.3 (25113013), with a Microsoft 365 Subscription license. Since yesterday morning, in the New Outlook interface, my inbox has suddenly appeared empty, and I constantly receive the following error message: “Failed to refresh subscriptions.” It’s important to note: In Legacy Outlook, everything works perfectly. The web version and the Outlook app on my mobile phone also work well. The issue persists regardless of the network I am on (home, office, cellular, etc.). Troubleshooting steps I already tried: • Updating Outlook to the latest version • Removing and re‑adding the account • Clearing cache and preferences • Formatting my Mac and reinstalling everything from scratch Unfortunately, none of these steps has resolved the issue. Is this a known bug, and is there a recommended workaround or an upcoming fix? Appreciate assistance on that issue.
Send Button Greyed Out For New Messages
This morning, I am not able to send new emails form outlook 365 on a Mac. I can type a message and put in a recipient but the Send button stays greyed out. I have quit and relaunched Outlook and am still having the issue. Any advice on how to resolve? I am able to create and send through the Outlook app on my phone and I am able to reply and forward form my computer. I just cannot create new messages form my computer.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
Outlook broke after Office 365 update to 16.0.19328.20158 – cannot open emails Windows Server 2016
Hello everyone, posting to report that after the latest automatic update to Microsoft Office 365 version 16.0.19328.20158, we are experiencing a critical issue on multiple company machines running Windows Server 2016: The Outlook desktop application launches normally, but when trying to open any email, the following error appears: “There was a problem opening this item... The text formatting command is not available... Reinstall Microsoft Outlook.” Launching Outlook in safe mode (Outlook /safe) does not help. Creating the FORMS2 folder (suggested workaround) does not fix it. Attempting a downgrade via OfficeC2RClient.exe fails with error 30183-27 (400). Quick/online repair from Control Panel also has no effect. In our environment, this issue appeared simultaneously on many workstations and servers, right after the Office update today. Temporary solution: We are instructing users to access their mail via Outlook Web App (OWA), which is not affected by this bug. We would like to know: If others have experienced this bug with this build, including on Windows Server 2016 If any working workaround exists, or an official fix timeframe from Microsoft Thanks to anyone who can share their experience or updates!Significant changes to the New Outlook Calendar Event User Interface

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.
