Issue Description: Users are encountering an error when reporting messages as junk in Outlook on the web.

More info: Users may have seen the following error message –

While we were working toward remediation, affected users could have used the Outlook desktop or mobile clients as a workaround.

Final Update: 29/03/2022 08:34:00 AM – Microsoft reverted the offending change and confirmed with internal telemetry that the issue is resolved.

Next steps : Microsoft are reviewing the regression in the recent service update to better understand what caused it and to assess how the problem wasn’t identified during their update testing procedures.
