How to find which mailbox is the primary mailbox of one specific archive mailbox in Exchange 2013 via PowerShell? In Exchange 2013, using Get-MailboxStatistics cmdlet against one mailbox database, I can get a list of mailboxes, including archive mailboxes, in that mailbox database. Base on this list, how can I get its primary mailbox of each archive mailbox? Thanks!

Hello, By default, the display name for archive mailbox is like this "Personal Archive primary mailbox name", so you can get its primary mailbox of each archive mailbox from the display name. Get-mailboxStatics -Database "Mailbox Database"|fl DisplayName If you didn't use the default display name for archive mailbox, you can use this command to help you find the primary mailbox: Get-mailbox| where{ $_.ArchiveName -like 'Your Archive mailbox's DisplayName'} Thanks, Evan Liu TechNet Subscriber Support in forum If you have any feedback on our support, please contact tnmff@microsoft.com Evan Liu TechNet Community Support

Thanks Evan! Yes, it works. But there has one scenario, if each user mailbox has one associated archive mailbox and I only have a list of all archive mailboxes, to find each primary mailbox for each archive mailbox, the time complexity of your solution will be O(n^2). The solutoin what I want to find is O(1), just like from primary mailbox to find associated archive mailbox the time complexity is O(1). Is there has such similar cmdlet, from archive mailbox to find primary mailbox, in Exchange Server 2013?

Hello, You can follow this way to list all the primary mailbox name and archive mailbox name: $MailboxGuids=(Get-MailboxStatistics -Database "Archive mailbox Database").MailboxGuid Foreach($MailboxGuid in $MailboxGuids){ Get-Mailbox| where{$_.ArchiveGuid -eq $MailboxGuid}|fl DisplayName, ArchiveName In this script, it will return all the primary mailbox name and archive mailbox name for all the archive mailboxes on that archive mailbox database.
