Azure AD B2B Permission review

Hi folks,

 

I got three questions struggeling around with B2B Accounts.

 

1. if I remove a B2B Account are also the permissions deleted (i. e. sharing of SharePoint, Teams, etc.)?

2. only if the answert to the first question is NO: If I reinvite a previous deleted B2B User, does he get the same permissions as he has previous to deletion?

3. Can I restore the 'guest object' belonging to the B2B account?

4. Can I get all of the sharing permissions of a B2B account with an API (like graph, i. e.)

 

many thanks in advance
