List all Disconnected Mailboxes with timestamp

I came across a situation where someone was messing around in AD and had accidentally deleted an account, Realizing their mistake they re-created with the same password it thinking it would just re-connect to the mailbox and the user would be fine.  By the time they called me they had deleted and re-created the account a number of times.  I had to identify the correct mailbox to reconnect to the user account, out of 4-5 versions all with the same exact name.

This command shows all disconnected mailboxes as well as the date the corresponding user account was deleted, and leaving the mailbox disconnected. The timestamp allowed me to connect the correct mailbox to the account without having to guess at anything.

get-mailboxserver | get-mailboxstatistics | where { $_.DisconnectDate } | fl DisplayName, DisconnectDate
