Access Denied Page blocked as it violates the Acceptable Use Policy

thanks for the answer.

Sadly account recovery form works only for blocked accouns. not if only the access to onedrive is blocked.

I'm already in contact with m365 support.

not really hel0ing. they changed per remote access several of my Azure settings. to no avail. ofc.

after I repeated again and again to have a look on the onedrive web page they noticed what is wrong. not that I haven't told them several times and made it the header of my support request. ;)

than I'd been told to create another tenant and forget the old one. 

great advice to lose the data. no help for me.

right now I've been told to buy a new subscription cause they can fix the issue only with me having an E5. But my E3 developer subscription is valid till 12/26. and it includes onedrive and sharepoint. no way i'm spending thousands on a new subscription while I have a valid one.

It gets crazier by the minute and I still have no access to my data.

makes me really regret my decision for MS.
