We have few calendars which are part of user mailboxes specifically used for meeting room bookings. I would like to either change them to resource mailbox without losing the existing entries or would like to disallow conflicts. I know we can disable conflicts if the calendar is created as resource mailbox but not sure how to do it if its created as user mailbox. Someone please help. Server:Exchange 2010

Hi, You can use this command : Set-Mailbox “MailboxName” -Type Room Have a look into this article http://exchangepedia.com/2007/04/how-to-convert-a-user-mailbox-to-a-resource-mailbox.html & do let us know in case of any issue.Ripu Daman Mina | MCSE 2003 & MCSA Messaging | MCC
