Latest Message<\/th>\nTitle: Some admins may be unable to run the command Get-MailboxStatistics and get an error<\/p>\n

User impact: Admins may have been unable to run the command Get-MailboxStatistics and got an error.<\/p>\n

More info: Some admins attempting to run the command may have seen the following error:
“Write-ErrorMessage : ||Cannot find MailboxStatistics objects from the root ‘[Mailbox database]’. Please make sure that you specified the correct search root and that you have the correct permissions to perform the search.”<\/p>\n

“Get-MailboxStatistics: ASSERT: Attempting to convert large prop tag to 32-bit form”<\/p>\n

As a workaround, affected admins could run the command “Get-EXOMailboxStatistics”<\/p>\n

As an additional impact scenario, users may have been unable to see usage details for both primary and archive mailboxes in Outlook on the web, and some users may have also been unable to use the ”New-MailboxRestoreRequest” command.<\/p>\n

Final status: We’ve confirmed that our fix to reverse the recent offending change has completed deployment to the affected environment and the issue has been resolved.<\/p>\n

Scope of impact: Some admins attempting to run the command Get-MailboxStatistics may have been impacted. Additionally, some users attempting to view primary and archive mailboxes in Outlook on the web may have been impacted.<\/p>\n

Start time: Tuesday, July 22, 2025, at 1:30 AM UTC<\/p>\n

End time: Thursday, July 31, 2025, at 12:00 AM UTC<\/p>\n

Root cause: A recent service change, designed to add a new property to the Get-MailboxStatistics command, was causing impact.<\/p>\n

Next steps:
– We’re reviewing our standard update procedures for to ensure similar issues are caught during testing and addressed ahead of deployment to prevent this from happening again.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
