Starting a few months ago some of our users are reporting that Outlook and Teams disconnect multiple times throughout the day. The only way to fix it is to reboot the machine. They are using Outook for 365 and connecting to a mailbox in Exchange Online. It started with 2 users but more have reported the issue recently.
During the time Outlook & Teams disconnect they do not loose network or internet connection and can open Outlook and Teams on the web.
So far I have tried:
I have listed below the version of Outlook and Window 10 they are using.
Microsoft® Outlook® for Microsoft 365 MSO (Version 2205 Build 16.0.15225.20348) 64-bit
Windows 10
OS build: 19044.1766
Using Classic Outlook on Windows for personal email, calendar, and contact management

Have any of you tried uninstalling Dell Optimizer? Apparently that has worked for some folks in the very recent past. It has not worked for my issue, but ours may be a bad network (our only users having the issue are in one small office). Something to do with it installing ExpressConnect
I've been working on this every day for the last two weeks. One thing that seems to be consistent between all our users is that they recently received upgraded computers. All the computers were newly added to the domain and the users were existing users. The computers are Windows 10 and 11. I have not wiped the computer and reinstalled windows. It will be very time consuming if we have to start wiping all our computers.
Same problem here. Windows 11. We have hundreds of Windows 10 machines with no issue, but 50% of the test machines on Windows 11 have this problem.
Teams can be 'fixed' by running the Windows compatibility troubleshooter. End result is that it sets Teams to run in compatibility mode for Windows 8 and then Teams will function normally.
Have not been able to similarly fix Outlook. Every hour or two Outlook will go to "Trying to connect" and no longer be able to send or receive data. Rebooting the PC will temporarily resolve the issue. Reinstalling Office, repairing Office, and even reinstalling/reimaging the PC with a fresh Windows 11 load does not fix the problem.
The Microsoft Support and Recovery Assistant (SaRA) also does not resolve the issue after allowing it to clear saved credentials, recreate Outlook profile, etc. Nothing works except restarting the PC.
I' have the same issue on couple PC's. On few of them were reinstalled Windows and everything works fine. But issue are showing on next PS's....
PC's are individual machines, and are compliant, managed from Intune.
We are also having the same issue with roughly five users impacted. The odd part is 4 out of 5 users received a new laptop recently. On their old computers they had no issues with Office products.
We've tried:
