Deleted Items folder retention – Office 365

Hello folks,

This content is very short but we considered very useful.

To increase the default period – 14 days – for deleted items from Deleted items folder, we can increase up to 30 days

To see the RetainDeletedItemsFor for mailbox, run the follow command:

Get-Mailbox -Identity user@domain | fl *Ret*

To set the new value – in this case 30 days – run the follow command:

Set-Mailbox -Identity user@domain -RetainDeletedItemsFor 30

To check if the command has succeeded, run:

Get-Mailbox -Identity user@domain | fl *Ret*

Is very important see the limits in Exchange Online. To do it, check Exchange Online limits
