Hello everybody! Faced with some trouble - need to permanently delete old messages (older than 30 days) from mailbox. So my steps were:

1) I created new retention policy tag: Name "Delete_30_days", Type "All other folders in the mailbox", Action "Permanently Delete", Age Limit "30";

2) I created new retention policy: "Info_Delete" with tag "Delete_30_days";

3) I attached this new retention policy to one of my mailboxes: Recipient configuration->mailbox->mailbox settings->messaging records management->Apply retention policy "Info_Delete"

So I think this is OK. But: if I open this mailbox - there are no any reminders about 30-days age of inbox messages. Seems to me retention policy is not active. How can I check it? Thanks for answers.

The issue occurs because the retention policy runs automatically one time every 7 days for mailboxes that are larger than 10 MB. However, the retention policy does not automatically run for mailboxes that are smaller than 10 MB or within 7 days work cycle.

To resolve the issue, manually run Start-ManagedFolderAssistant Identity <mailbox> cmdlet to force Managed Folder Assistant to process the specific mailbox
