Hello,
Suddenly the connection with Outlook 365 and also Onedrive is lost with the Microsoft server this on Windows 11 Pro . So both Microsoft applications have lost connection.
There is a purple ! mark on the outlook icon. I have changed nothing in the settings the outlook was open and suddenly no new mails came in.
When i go to Onedrive the same issue onedrive is not accessable.
I have already done a repair of Microsoft 365 not solved.
Downloaden the Rapair assistant form microsoft ( SetupProd_OutCon) to check the connection. This is always asking if this the computer with no connection. When i click YES there is a pop uw window that is going away so fast that i cannot read it.
So i am completly stuck and dont want to reinstall my windows ifd not needed.
Anyone has suggestions ? I have looked in the internet settings the TLS 1.2 and 1.3 is checked.
I didn't change any settings so the problem was there without installing any new software or done any changes.
I have tried to reconnect the Onedrive and after entering my email adres there is a error 2603 and message NO Networkconnection so i cannot enter a password this message is there just after entering the mail adres.
Thanks
Dca

Hi @Dca
So that we can know if the issue is related to your server or account or your device/client
And could you please share any screenshot about your issue?
Hello,
Thanks for the response.
When i go to OWA there is no problem even on the pc where the outlook and Onedrive have lost connection i have no issues to see the mails webbased.
Also on my ipad and iphone no problem so only on my Pc is the Outlook and Onedrive damaged this happend at the same time.
When i try the Sara Tool there is a strange message like i mentioned in my question that it is always asking if this is the pc that has the issue (this i translate myself) and it is in a loop i can only answering yes or no. When answering yes there is a pop up window that is flashing on the screen but not readable and the question is there again if this is the pc that has the issue ....
So i think that i cannot use the SARA tool...
I dont want to complete reinstall my pc if not needed but i cannot wait also to long because working like this is very diffucult with no onedrive and no working outlook.
Also tried to set the PC to earlier restore point but this has failed due to a error in Onedrive. Something with files that are online and not local.... So it starts to restore and after the restart message that it has failed. I have tried different resotore points.
Thanks
best regards.

Update on my previous reaction.
I have created a new user account on the PC and configured outlook there and it was no problem.
The mails are coming in to the outlook so 100% sure that there is something wrong someware in the user account and not in the complete windows.
I would prefer to repair it because otherwise i need to reconfigurate every program i use again.
But i cannot wait a lot longer so if i cannot solve the issue before the weekend i will reconfigere everything again on the new account in the weekend.
When i have tried to set the pc back to earlier restore point there was a error something that Onedrive has a file that is online and since the connection is not working the restore was not done ...
So restore point nothing usable.
Already removed Office 365 and reinstalled problem still there.
In the new test account no problem....
So i think someware in the connections to Microsoft 365 server this for Outlook and Onedrive (maybe the same) there must be something completly wrong.
I anyone has a suggestion thanks
best regards

Hi,
Thanks for sharing more information, according to your description above, your issue seems to be more related to your current windows profile.
And like you mentioned above, you could use a newly created test account, or you could rebuild your account's windows profile to test again.
Is there a way to reset only the connections to the microsoft 365 server ?
When i create a new mail profile in the non working user account this is also not working. Same for OneDrive . So it is onlt the connection to every application to 365 server that is giving issues.
Dont know what i can try anymore . In the new user test account the outlook is working without any issues.
So the Windows self is ok only something in the connection to 365 that is locked.
Strange
Maybe there is something that is resetting the connection to the 365 to default but i cannot find it.
Like i mentioned before i cannof wait and try much longer if it is not solved i will configure everything again in the new Test account.
So if there is someone with a idea it is mostly welcome.
Thanks
Dca
Since there is no reaction on my problem i will reinstall everything on a new profile . I cannot wait any longer so reactions are no longer needed.
Thanks to 'joyceshen-MSFT' who has given a few suggestions.
