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
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.
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!
outlook contacts continuously restore themselves
I decided to clean out my contacts in outlook, so I exported them all out to a .csv file and then I deleted all 1,200 of them (100 at a time, because apparently microsoft feels that any higher amount would be bad...). Then I spent a few hours in excel combining, consolidating and deleting them down into about 600 contacts. When I went back into outlook and clicked on people, to my surprise all 1,200 of my original contacts were right there again as if I'd done nothing. I figured that some other device must be restoring (through some normal synching process), so I turned off **REMOVED** computers and phones that I've ever used to access outlook). Then I deleted all of the contacts once more, this time using the OWA webpage with my local outlook completely closed. Unfortunately, the exact same thing happens. After repeating that process several more times last night, I shut down my laptop and went to bed. I got up this morning, opened my local outlook app, clicked on people and there were no contacts there at all. For about 5 seconds I was happy, until all 1,200 of them instantly popped right back up like a really bad joke or a dream. Something either on my computer or (I suspect) on microsoft outlook servers is automatically forcing a complete restore of all my contacts. Two side notes: 1) I can create/add and delete single contacts and those changes seem to stick, and 2) I can delete all contacts except a single one and that seems to stick, and 3) I can import my cleaned up .csv file containing 600 contacts back into outlook (with only the one single remaining contact in there), it says that all 600 contacts have been successfully imported, and then within minutes - all 1,200 contacts are back right where they were in the beginning. The truly frustrating part about this issue (and most companies these days), is that IF the customers could possibly **REMOVED** about it so that we can simply continue to make and sell more stuff. It's very sad
