Another great question from mario this week.

I have shared rooms for meeting spaces in 2003, how can I convert them to room mailboxes in 2010?

 

You can convert the following:

  • User mailbox to shared mailbox
  • User mailbox to resource mailbox
  • Shared mailbox to user mailbox
  • Shared mailbox to resource mailbox
  • Resource mailbox to user mailbox
  • Resource mailbox to shared mailbox

You can’t use this procedure to convert a user mailbox to a linked mailbox or a linked mailbox to a user mailbox. For instructions about how to convert to a linked mailbox, see Convert a Mailbox to a Linked Mailbox.

A scenario in which you may want to convert a mailbox is if you have moved resource mailboxes from Exchange Server 2003 to Exchange Server 2010. In Exchange 2003, you use shared mailboxes to represent resources. When you move these mailboxes to Exchange 2010, they will be Exchange 2010 shared mailboxes. You must convert them from Exchange 2010 shared mailboxes to Exchange 2010 resource mailboxes so that they will have all the properties of Exchange 2010 resource mailboxes.

Regrettably this can only be done via the Exchange Management Shell using the following syntax..

 

Set-Mailbox ConfRoom1 -Type Room

You can use the following values for the Type parameter:

  • Regular
  • Room
  • Equipment
  • Shared

For detailed syntax and parameter information, see Set-Mailbox
