Outlook Disconnected MFA causing issue
Yup - identical experience. Multiple disconnects per day - particular after coming back from hibernation. Connection status showing error in authn column. Other Office apps impacted too as they will hang when trying to access SP/OneDrive. Only option is to reboot. Went even further than you - completely wiped machine and rebuilt but issue came back. Deleted OL profile multiple times. Searched high & low for answers but no joy.
Also believe that this is related to MFA as I only ever experience this when out of the office. The office egress IP is defined as a trusted location so users never get prompted for MFA when here. My machine works flawlessly all day when here. Deeply frustrating...
I’ve mostly given up and pushed the people having issues to the PWA, seems to slowly be a cascading nightmare every couple of weeks a new person same issue. Not even sure where to go with it.
Quick follow-up on this one. This is not definitive and I'm still testing...but results so far are interesting.
I was noticing that when the issue happens, it's not just Outlook. Issues with SharePoint files not saving/syncing and very odd issues with our corporate VPN where I could connect and ping internal resources but not access any web interfaces.
I also noticed that when I recently spent several days in another location and exclusively on wi-fi, the issue did not happen once.
Long story short, I found that the issue happens when at home or in the office (forget the previous comment about the issue not happening in the office - it did happen!) and when connected via ethernet (using a dock) and connected to wifi at the same time.
Still testing...but at this point, if I disable wifi when docked, the issue does not happen.
My device is a Dell Latitude 5420. Would be curious if anyone else can confirm this behaviour. Will revert back after a few more days of testing.
