Q:	How do I open another user's mailbox in OWA 2007?
A:	Note: To use this feature, you must be granted FULL ACCESS to another user's mailbox that you wish to open. To open another user's mailbox: 1. Please login to OWA using your own mailbox email address and password. 2. Click on your name in the upper right corner of the window. 3. In the "Open Other Mailbox" dialog box, please enter the name or email address of the mailbox that you want to open. 4. If more than one matching entry is found, Outlook Web Access will list them all. 5. Choose the mailbox to open. The mailbox will open in a new window. Troubleshooting If the mailbox doesn't open and you get the following error message instead: "You do not have permission to open this mailbox. Contact technical support for your organization for access or for more information." You need to make sure that you were granted FULL ACCESS to that mailbox. Note: If user A has calendar delegates permission from userB. UserA can open userB's calendar by using the following link: https://yourOWA.yourdomain.com/owa/userBemailaddress@yourdomain.com?cmd=contests&module=calendar
