The tenant for tenant guid does not exist - Trying to share App with external Users - Office 365 Outlook Connector

[MiLoCore]

Hi 🙂

I have an issue by sharing my Canvas App with external users.

The external user I shared the app with get the request to login:

And we he try to login to the Office 365 Outlook Connector he get the error message:

The tenant for tenant guid 'f8cdef31-a31e-4b4a-93e4-5f571e91255a' does not exist. Only work or school accounts are supported.

Two weeks ago I tried this with another external Account (as well a @Outlook.de address) and there was no problem!

I'm using Pro App Licenses for all users.

And in the powerapps admin backend I see that the accounts are listed and the licenses are correctly assigned.

Maybe Microsoft has some problems here?
Or does anybody else have an Idea where I should look?

I already deleted the Office 365 Outlook Connector from the app but powerapps still promt this again!

Thanks a lot for any help

Michael

Oh 🙂 I did not notice that external users do not have permission at all using the Office 365 Outlook Connector^^
Sorry for the disturbing 😉
