Microsoft 365 Outlook Classic Latest Update Copilot issues
Yes, this is a known issue after some recent Outlook Classic + Copilot updates in Microsoft 365. Many users are reporting slow performance, sync problems, or Copilot not loading properly after the update. In most cases, it can be fixed by restarting Outlook, checking for the latest Office updates, or repairing the Office installation. If the issue still continues, creating a new Outlook profile or rolling back to a stable version often helps resolve it.
I had tried all the above you mentioned and nothing made copilot work; Update / refresh License in the outlook classic app, uninstalling and re installing office, install the latest update available, including the creation of a new profile.
Just this morning I noticed that it worked out of the blue.
Just now , I got the notification that a new update is available (Build Build 16.0.20026.20140), installed it, and copilot still works. However I will keep my eye on it from time to time.
Not sure what solved it, but it seems that the installation of the general copilot app on my laptop might have changed something.
Again this is just what I am guessing and what I experienced first hand.
