I have one particular user in an Exchange 2003 / Windows XP / Windows Server 2003 network who we cannot share out his mailbox.
When clicking the properties for his mailbox the window that normally shows the "Permissions" tab has this particular tab missing.
I have arleady searched and found the following but this did not resolve the issue:
Also I have tried going to the Others option to grant permissions thorugh delegates, but when I grant say, my user permissions to the users mailbox, and give myself editor permissions, when I OK and then come back to the same page I noticed the settings have not been saved.
What is going on here?
