M365 Groups: Unable to set "ReportToOriginatorEnabled" or "ReportToManagerEnabled"

[Daniel Smith]

For the "Set-UnifiedGroup" cmdlet, there aren't parameters to set either "ReportToOriginatorEnabled" or "ReportToManagerEnabled".

We have a very large group which primarily consists of external guest users.  We'd like to avoid seeing NDRs sent to the other members when they email the group and some of the other members' email addresses turn up as no longer valid.  We'd like to keep things clean for everyone and evaluate the NDRs administratively.

Groups usually suppress the NDRs, but in case you are seeing such, you can always create a mail flow rule to "capture" them.
