Show hidden disconnected mailboxes

A few days ago encountered a wonderful thing, the company is doing Office365 Exchange online hybrid deployment. When a user migrates from a local Exchange server to a Office365, the user account disappears!! Yes, you did not read wrong, inexplicable disappeared. I did not disable or delete the user locally, but the user mailbox database was missing. Of course, this issue we have submitted case to the Microsoft Office365 team, specific reasons to be identified, I will be sent to the blog.

Today, we mainly share the process of retrieving this mailbox data.

1. Before dealing with this problem, I will first look at the "disconnected" mailbox on the local Exchange server and find that there is no mailbox for that user. Does this user's mailbox really "evaporate"!?

2. As a result of not forget, board the server to use the command to check

In the list and find the disconnected user we need, the results are not found. Tragedy ~ ~ ~

3. Later, after reviewing foreign devil's data, it was found that the mailbox database data could be re-consolidated by clearing the mailbox database, similar to the "refresh" in the PC

Here to focus on the Exchange 2010 and Exchange 2013 commands are not the same, this is also a long time to find out, the dead AH ~ ~
