Legacy mailbox type in exchange 2013

Hi all

How do I fix the Legacy mailbox type in exchange 2013, our exchange 2003 server broken down a month ago, and recently we had installed exchange 2013, and found out that all the user mailbox type are legacy, how do I make the legacy mailbox type back to normal ? I have tried to new a mailbox and choose exist user, I was able to recovered some of the mail account, but still was not able to find it, any ways that I can fix this problem , thx

You cannot remove the mailbox without removing the domain account. You can try disabling the mailbox but I am not sure how that will help you.

Have the mailboxes been moved to an Exchange 2013 Server?

You can use the following  command from the Exchange Management Shelll to test one and see if it works

Set-Mailbox alias -ApplyMandatoryProperties

Open in new window


To change all of them use the following command from Exchange Management Shell

Get-Mailbox -ResultSize unlimited  -Filter { RecipientTypeDetails -eq “LegacyMailbox” } | Set-Mailbox -ApplyMandatoryProperties

Open in new window
