Exchange: Make new retention policy as default and Apply all mailboxes

--Anand-- Computers and Internet December 22, 2018 1 Minute

After you created an Exchange Retention Policy either in Exchange Online or On-Prem Exchange, you have to make this new retention policy as Default, so new mailboxes will get this policy automatically.

To see the available retention policies, type

Get-RetentionPolicy

To change your Default Retention Policy for all users, run the following (Copy the retention policy name from the results of the above command):

Set-RetentionPolicy -Identity "Your Policy Name" -IsDefault:$true

Now, we need to assign this policy to all existing mailboxes.

Get-Mailbox -ResultSize Unlimited | Set-Mailbox -RetentionPolicy "Your Policy Name"

That’s it. Enjoy!

doesn’t seem to work on-prem with Exchange2016
A parameter cannot be found that matches parameter name ‘IsDefault’.
