I recently received this email in my inbox so I thought it would be a good idea to dedicate a post answering this question.
First of all, I'd like to thank you for you blog, I used your guide to set up an Exchange 2010 multi tenant set up and it worked like a dream! Very clear instructions, just what I needed to guide us through the potential minefield!
Do you have any blog posts or examples on how to bulk create mailbox in a multi tenant environment, I'd like to a take a spreadsheet with users name, e-mail address etc. and create multiple mailboxes using a powershell script. I'm a GUI man at heart and I find powershell tricky at the best of times. I saw your blog on how to import PST files which I also think will be very useful.
Any help you can offer would be greatly appreciated.
Before getting started, and if you are new to Exchange 2010 multi-tenant mode I suggest you check the list of tutorials I wrote : Exchange 2010 hosting for hosters.
For this tutorial I am using a single exchange server in hosting mode running all the roles, but the number of exchange servers you have in your setup will not change anything.
I have also created 2 test organizations for this tutorial TestOrg1 and TestOrg2.
