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.

I have users across my org who are having this newest update crash Outlook vs not having emails in it. It starts happening immediately after the update :(. You don't even have to be actively using Outlook.
note to everyone on a mac- don't update Outlook to 16.103.3Thanks for sharing the warning! This is essential information. I also noticed similar issues after updating, so it’s good to see it’s not just on my end. If you hear of any fixes or workarounds from Microsoft, please update!
