Developer Tenant External User Messaging Issue

Hi everyone

 

I have a Microsoft 365 Developer Tenant which includes 25 Microsoft 365 E5 Developer licences.  I have been messaging a friend who is external to this tenant and it has been working fine up until around 2 weeks ago.  Having looked into it, this seems to have coincided with Microsoft enforcing the policy to block federation with Teams trial-only tenants.

 

Am I right in thinking that my developer tenant is considered a trial-only tenant in this instance?

    MZONDERLANDgjayne84 I have the same issue, it works "internally" with the E5 license but not externally with other tenants. (I haven't tried to do dev to dev though)
    This happened around the time they removed the teams license from regular E5 licenses for at least EU.

    gjayne84it seems to be I have the same issue, having multiple tenants, developer tenants using for testing purposes, but it seems to be I cannot chat anymore to Developer Tenants from Production tenants via Microsoft Teams, seems to be related trial tenants are blocked.
