Microsoft 365 Outlook Classic Latest Update Copilot issues
Hello to all, we are currently using the Microsoft 365 Outlook Classic, using version Version 2604 Build 16.0.19929.20172 (Current Channel) Copilot works as expected;
However ever since the next update was released (Version 2605 (Build 20026.20076)) some users including me, have been getting the below error:
I have tried uninstalling and installing the latest version directly, with the same issue. Scanned for any corrupted system files with no issues,but still get the error; I have tried the update Licence from the Outlook application, with no issues but the copilot something went wrong error keeps on persisting. Internet searches are very vague and the I have found some registry suggestions which I have also tried with no solution.
The only way to get Copilot working on Outlook Classic was to revert to a previous working version, only then Copilot works as expected. This only happens in Outlook Classic; Copilot works fine on the latest version of Microsoft Office 365 with Word, Excel, etc.
For those that maybe might ask why not switch to the New Outlook, we have had issues with it and it has been recommended to use the Classic Outlook for the time being.
Has anyone been experiencing such issues please?
Thanks for any help.

My organization is experiencing the exact same behaviour in Outlook Classic, just with the "Coaching" feature - other Copilot features are working. Our workaround is to use Outlook for web or Outlook New. I have reported it to Microsoft for investigation.

I was facing the same issue earlier. After switching from Classic Outlook to the New Outlook, I was able to use Copilot successfully.

However the issue still persists; good to know it seems we are not the only ones experiencing such issues.
Awaiting any feedback on a possible fix for this issue please...
