External Access issues OneDrive for Business & SharePoint Online (O365 Business Premium)
Anything else you want me to check?
Did you create a conditional access rule that requires MFA?
AFAIK, I have no way of enforcing MFA for guest users. This requires Azure AD Premium. I'm pretty certain that the MFA issue was caused because my Azure AD Premium trial ended and I wasn't able to reach that setting. Latest update from Microsoft support is that they removed the MFA and I'm now not facing that issue anymore. The issue I'm facing now is that after sharing a file from OneDrive, the guest user has to request permission. Permission is then granted, the guest user has to ask for permission again and this will loop until the end of time.
They fixed the MFA issue, but I'm still experiencing external sharing issues while I created this ticket on the 1st of November. Imagine that...
External sharing still not fixed. Microsoft is still "investigating". External sharing has been broken for my tenant for almost 3 Months...
