primärer Alias kann nicht bestätigt werden // my domain need to allow Microsoft to access...

Well my friend, unfortunately there's nothing we can do to help you. You'll need to contact Microsoft Official support for business to see if they can delete the old tenant for you.

Hallo,

habe schon eine Lösung gefunden: https://superuser.com/questions/1095660/how-to-access-exchange-shared-mailbox-from-thunderbird-different-domains

Anscheinend akzeptiert Office andere Domains beim Login nicht. Mit Alias klappt es super.

Viele Grüße,

Paul

I think you dont understand.
I got back my emails and the account, BUT to recover accounts on other sites connected with this old "s****** Die E-Mail-Adresse wurde aus Datenschutzgründen entfernt. ***" I need to get those emails.
But as I deleted the alias "s****** Die E-Mail-Adresse wurde aus Datenschutzgründen entfernt. ***" to be more protected against this hacker, I noticed that I also cant receive emails sent to this adress. That was never mentioned during the delete process. And thats why I need the help of the technical support to implement back the possibility to receive emails to that adress ... !

I believe the API you are using needs access to Azure Active Directory, but you would need to consult with the documentation to confirm this, or a software developer for further assistance.

Kind Regards,

Hi,

I'm Nik, an independent advisor here to assist you with this.

I understand your concern is regarding possibility of your company being able to access your data on Personal OneDrive.

Please find my answers in the same order:

1. If you have enabled sync from your personal OneDrive to local folder and your company has any rule/policy enabled to scan/access your local files, then they could possibly access those files.

2. Folders that are 'Online' available only will not be accessible as they would need your credentials to access.

3. Admin will not be able to login to your Personal OneDrive as that would also require your credentials.

Regards

Nik
