We have 2 domains in O365 Tenant & are in process of migrating to 1 domain and while we are sending mails via Teams Group mail ID, participants with abc.com receives the mail and other participants with xyz.com does not receive, rest all features for Teams are good
Do you mean to the Channel emailaddress or to the group emailaddress?! Are the member from different domain part of the same group/ team or are they in separate groups? Either way the mail should be delivered in the group or the channel! Please elaborate further..
