For most Office 365 tenants there is a list of one or more extra acceptable domains for which email can be sent to the tenant for routing and acceptance. For some large tenants, this list can be quite large. The accepted domains solves the problem of having to track down and get all these accepted domains together and simply puts it into one list with this report.
The report is simplicity itself. After selecting the report the list of acceptable domains will appear.

As with all of the reports, this information can be customized, filtered and scheduled.
