Removing a mailbox does not remove it from the get-mailboxstatistics

Question

I used get-mailboxstatistics to get a list of mailboxes on the server.

I then manually removed one of the mailboxes using:

Use the EMC to remove a mailbox

1. In the console tree, navigate to Recipient Configuration > Mailbox.

2. In the result pane, select the mailbox you want to remove.

3. In the action pane, under the name of the mailbox, click Remove.

4. A warning appears asking, Are you sure you want to remove 'mailbox name'? Click Yes to remove the mailbox.

When I re-ran the get-mailboxstatistics command, the mailbox I removed, still came up in the list from the statistics.

Why is that and how do I properly remove a mailbox?

Answer 1

The mailbox will still be retained for a period of time based on your Mailbox Retention settings. Until that time, the mailbox is only Soft Deleted. You can force a mailbox to be deleted using the Remove-StoreMailbox cmdlet.
