Exchange 2003 : Exmerge Permissions Problem

Solution that worked for me (14/03/03) >

You should have to give your account permission to enter all messages in all data stores.

The access to user mailboxes is controlled by two permissions Send As / Receive As , you can grant your account those rights in the Exchange manager then you will be able to access all mailboxes.

To do it open the Exchange system manager locate you server on the permission tab remove the inherited permission select copy and remove the deny Send As / Receive As from the groups you are member of.
These are domain admins and enterprise admins grant your account those two permissions.

Or give the permission at the organization level >

Add the following registry key

HKEY_CURRENT_USER\Software\Microsoft\Exchange\EXAdmin New dword 'ShowSecurityPage' value=00000001
After you add this key you will find the permission page on all objects.
In the level you want (you can do it for all the organization)
Remove the deny from the send as and receive as permissions from the groups you are member of the default is deny to the domain admins and enterprise admins )
Grant yourself those two permissions.
