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
