Microsoft Teams guest users cant access files

Hi All.

 

We have enabled guest users from external organization.

The guest users can access a Teams. But they can’t view files within File Tab

 

  1. Teams Admin Centre >> Guest Access is turned ON.

  2. M365 Groups have been checked.



  3. SPO Site for that that Teams has following settings

    IMAGE

    NOTE: There is only Blocked Domains and not additional domain for this setting. 

  4. SPO sharing options have been configured like this:

     


  5. User is added in AAD



  6. But use claims he access Teams but NOT access files tab


    Microsoft teams.  Access denied.   You do not have permission


  7. I did tried reproduce it and I got the same Access denied message in one my test tenants. 

  8.   But when I add Allowed domain in SPO for that site
  9. The Guest access (testing with my outlook.com) works. 


Its  not documented in Microsoft Teams to add domain SPO Admin Centre for guest access 
https://docs.microsoft.com/en-us/microsoft-365/solutions/collaborate-as-team?view=o365-worldwide

Please advice what I am is missing here. Thanks in advance.

  • aarohbits Hi, just one thing I noticed. Sure you want to use "Existing guests only" in the SharePoint site-level sharing settings and not "New and existing guests"? You have already added all guests that are going to collaborate?

     

    Just to be clear. I mean you cannot use that option and after the configuration is set add guests. They have to be in the org. already using that setting.
