Teams for Guest Users not working

Question

Team
. Since a few days, all added Azure Guest Users can not see their Teams content after logging into our Tenant.
. The invitation out of Azure works.
. Login with verification code works.

. Guest is in Teams and can be applied to Channels
. I can see it as administrator

. But the Guest User itself can not see Teams after login.

The direct access to PowerBI reports (link to a workspace or reports) is working for the Guest Users as expected.
That means: Users, Groups and User-2-Groups associations seem to work.

TY very for a hint ot fix. Reto

Answer

good day ky
my solution was too simple:

instead of creating a guest account like this:
group - user - user-2-group - invite
I tried it this way
teams - add user

the effect should be the same in my mind.
but it‘s not

now everything is fine.

another essential thing to me is the radical use of ms starting pages like teams.microsoft.com.

all this makes the enabling and usage actions very transparent.

many thanks to you and the team!!! till soon - reto

Answer

You should begin by checking if any SharePoint permissions (at site and organization level have been altered). Perhaps someone made a change that blocked external access for people viewing files on SharePoint (which is the backend of files for Teams).

1) Check the organizational-level settings found in SharePoint Admin Center (https://your-tenant-name-admin.sharepoint.com/) - Change the organization-level external sharing setting

2) Check the site settings - Change the sharing settings for a site

Hi @Reto Schneiter

Please also have a check of Microsoft 365 Groups guest settings.
Make sure Let group members outside your organization access group content is enabled.

This is still not behaving correctly for me. I have all the settings set correctly as indicated above. The issue I'm having is that no matter how I invite a guest user it's not a straight forward streamlined process for them to join Teams.

Option#1

Invite Guest user using Azure - This sends them an e-mail to 'accept invitation' which ultimately sends them to the location of Retro's screenshot above where there are no apps and nothing for them to do, I can't have that. You can then ADD them to Teams after which sends them a SECOND e-mail inviting them to Teams but I can't have multiple e-mails which causes confusion.

Option #2 - Do what Retro says above where you JUST invite a guest user via Teams. When you do this the guest user gets an invitation to join Teams right away. BUT when you click on the invite link, authenticate and walk through the multiple tedious steps of singing in multiple times, in the end you are met with Team/Channel unavailable message - "something went wrong, please try again later"

IF you go back into TEAMS and add that same user AGAIN then then show up in Teams under GUEST users BUT the end user will get ANOTHER e-mail inviting them to Teams causing even extra confusion.

Is there no straight forward way to invite a guest user to teams, have them get one e-mail and when they click on it it takes them to Teams and the channels? This surely can't be this hard. I've tested with literally about 30 test gmail accounts at this point and no matter which way I do things it's not straight forward and very difficult, and if I find it difficult as an Admin, imagine an end user.
