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
Removing Dell Optimizer fixed our issues so thank you to everyone who suggested it.
Removing DellOptimizer totaly did the trick for us !
We have a case open with Microsoft, yet, still no solutions.
Users are all on Dell laptops, Windows 10 and 11. Azure environment with Intune.
We have Dell, hybrid azure ad and also Intune.
However we mostly noticed this on Windows 11.
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.
