Problem:
How do I find all Office 365 mailboxes with forwards configured using PowerShell
Solution:
The below command will show all shared mailboxes that have forwards configured:
Get-Mailbox -RecipientTypeDetails SharedMailbox | Where {($_.ForwardingSMTPAddress -ne $null) -or ($_.ForwardingAddress -ne $null)} | Select Name, ForwardingSMTPAddress, ForwardingAddress, DeliverToMailboxAndForward | export-csv c:\temp\forwards.csv
In we can change the RecipientTypeDetails to use any of the below object types:
| Member name | Description | |
|---|---|---|
| None | ||
| UserMailbox | ||
| LinkedMailbox | ||
| SharedMailbox | ||
| LegacyMailbox | ||
