PST Capture - no mailboxes found for exchange online

PST Capture 2.0 is a great tool from Microsoft and works really well when migrating PST files into Exchange Online. I recently had a problem when trying to select destination mailboxes , The solution is really simple. You need to get your tenant server name and you can do this by browsing to and taking note of the server name and then entering it in the Exchange Online settings in PST capture as per the image below.

You can download PST Capture 2.0 HERE
PST capture requires Outlook 2010 x64
You can download Office 2010 x64 Service Pack 2 HERE

  1. Hi, thank you for this post.
    Is this only needed if you are running Server 2012, because when I did this on a 2008 R2 server recently I did not have to specify the server address it accepted

    1. Not strictly related to server 2012. I am glad it worked out for you first time. I have encountered the problem a few times. C2C PST Importer is a much better product than PST Capture from Microsoft.
