Fresh Win11 install, fresh Office365 install, Onedrive backup no connection to OneDrive-service

Hi community,

got a new laptop with win11. fresh installation, 

Installed Office 365 (family license) as first package.

No firewall/Antivirus other backup software installed.

Onedrive says it´s connected. But if I start to select folders (documents/pictures) to automatically backup, the feedback is

"Problem with connecting to the onedrive-service"

File length or file names can´t be the issue, same error if folders are empty (fresh installation)

 

No matter if I´m connected through my router (LAN/WLAN), hotspot on my mobile phone, neighbour´s network.

Tried all resetting options Microsoft and web search is giving. No other result.

 

Can anyone help me? 

trying to reach the support leads to "this support is currently not available"

admin

office 365

    You are almost certainly using the wrong Onedrive client (Business instead of Personal) or Windows Backup is overriding KFM.

    Did %localappdata%\Microsoft\OneDrive\onedrive.exe /reset complete successfully?

    Maybe then is Offline KFM database is corrupted…

     

    Last resort fix:

    Close OneDrive

    Delete folder: %localappdata%\Microsoft\OneDrive\settings

    Delete folder: %localappdata%\Microsoft\OneDrive\Business1 (if it exists)

    Restart OneDrive

     

    This forces Windows to rebuild the Known Folder Move configuration from scratch.

     

    Hope this helps you, if not please just ignore it.
