No Microsoft 365 admin portal will tell you about the set of email addresses assigned to Teams channels. Fortunately, it’s relatively easy to create a report with PowerShell and just a little Graph magic.
A change made to the storage location in SharePoint Online for email sent to Teams channels caused problems for people who created Flows based on a known location. Instead of having one big folder for email messages sent to a folder, it seems like Microsoft plans to use a new folder for each month. There’s nothing wrong with this approach, but it would have been nice if Microsoft warned people using the folder for automated processing that a change was coming. They didn’t.
