Is anyone seeing issues with the autofill of mail recipients not functioning within Outlook Web? This popped up for a couple of my users last week. We tried clearing browser cache/history, incognito/private browser windows, different browsers, different computers, all with no resolution.

On Monday, the user I'd worked with on this last week emailed me that autofill was working again. Then today, a different user who had the issue but not reported it submits a ticket that his autofill isn't working. I've got a total of 3 users out of 4000+ that have reported/submitted a ticket about the crippled autofill. I've tested on my PC and Mac, with Outlook Web and Desktop, in Chrome and Firefox, with my daily driver and my admin account, and it works fine all the way around for me (and as far as I can tell, for everyone else).

I'm not seeing any M365 health issues that seem to relate to this, and have submitted a report to Microsoft.

Based on the one user who had trouble, and then notified me it was working again, I'm assuming MS rolled some updates, found some issues, rolled them back, and then tried again, cuz Microsoft be Microsoftin'.

As a workaround, I've told the users having problems to click on the TO button, choose the Default Global Address list, and search there to choose recipients.

Anybody seeing similar behavior?
