How to check mailbox retention policy with powershell

Albert Gostick 91

Hi,
I have configured a new retention policy in O365 and applied it to user mailboxes. I wanted to be able to use Powershell to list the retention policy for each user to make sure I did not miss any.

Not having fun with powershell - what modules would I need to install and what would the commandlet be to run to show the retention policy on each mailbox. I don't use powershell a lot and each article I look up seems to take me down a dead end.

Thanks.

Hi Leon,

Took a while to figure it all out as I am rusty on Powershell but I finally got the modules I needed imported and then I could use this command to just see the retention policies on the mailboxes:

Get-EXOMailbox -Properties Name,RetentionPolicy | Format-Table -Property Name, RetentionPolicy

Just in case someone else gets here who is as unfamiliar as me, I had to

1) install and load the module (the first link in your response):

ExchangeOnlineManagement

2) then figure out how to only show the properties I wanted (Name and RetentionPolicy) because by default, you get all kinds of properties with:

Get-EXOMailbox -Properties Name, RetentionPolicy

So had to figure out how to show it as a table (easy for a regular powershell user but for me...)

Follow up question: I had to issue this command to get the module installed - should I be running a command after I am done to keep my machine safe:

Set-ExecutionPolicy RemoteSigned

Thanks for responding Dave - just to point out what I found - the Get-RetentionPolicy returns details about the retention policies set up in the tenant - handy for the future. What I needed was the Get-EXOMailbox command to return the policy on each mailbox.
