outlook loses connection with Exchange
Hi Yves_Dekort,
Please follow this action plan:
- Make sure your Microsoft 365 apps are current (up to date)
- Make sure fast start-up is disabled
- Command Prompt (as administrator): sfc /scannow + reboot
- Command Prompt (as administrator): DISM /Online /Cleanup-Image /RestoreHealth + reboot
- Create a new mail profile and re-evaluate (https://support.microsoft.com/en-us/office/create-an-outlook-profile-f544c1ba-3352-4b3b-be0b-8d42a540459d)
- If needed: reinstall the Microsoft 365 apps
Last resort: create and use a new Windows user profile
- Hi Matthieu,
Already done all those things except for the last resort.
And I was hoping to avoid needing to do that.Hi Yves_Dekort,
In the past, issues could also be resolved by removing the Microsoft 365 license and re-adding it to the account, but I don't think this is the issue here.
I suppose you don't have these issues with your account on other devices, such as other workstations, tablets, or smartphones?You could also create a Microsoft 365 support ticket. Microsoft support engineers can run diagnostic tools at the tenant level.
- Hi,
It's not a 365-license.
Don't know if this happens on other workstations, as I only use one machine.
Switching to another workstation is not a real option:
- as the issue only happens at irregular (and long) intervals, there is no way to be sure if the issue is workstation-dependant
- there is no other workstation available with the needed specs
