I need a report which includes all users that have a send as permission on their mailbox. Could anyone advise me ? Mir

Hello Mir, You can get report for whole environment for Send-As permission with below command... Get-Mailbox | Get-ADPermission | Where {($_.ExtendedRights -like "*Send-As*") -and ($_.IsInherited -eq $false) -and -not ($_.User -like "NT AUTHORITY\SELF") } | FT -Wrap You can export to CSV file with below command.... Get-Mailbox| Get-ADPermission | where { ($_.ExtendedRights -like "*Send-As*") -and ($_.IsInherited -eq $false) -and -not ($_.User -like "NT AUTHORITY\SELF") } | Select Identity, User, Deny, | Export-CSV test.csv Hope this helps....
