When i add a user to the BES Express configuration i see in the logfile this error:

MAPIMailbox::MAPIMailbox ServerDN=/o=zimbra.vanseenus.nl/ou=First Administrative Group/cn=Configuration/cn=Servers/cn=zimbra.vanseenus.nl/cn=Microsoft Private MDB, MailboxDN=hasloe@vanseenus.nl
[20401] (10/20 09:16:31.003):{0x17C0} {hasloe@vanseenus.nl} MAPIMailbox::MAPIMailbox - GetMsgStore (0x80004005) failed, MailboxDN=hasloe@vanseenus.nl, ServerDN=/o=zimbra.vanseenus.nl/ou=First Administrative Group/cn=Configuration/cn=Servers/cn=zimbra.vanseenus.nl/cn=Microsoft Private MDB

In other logfiles i see errors about not being able to get eid of the user.

My first user i had add, had the same problem. This was solved by using the same user in the outlook profiles. (This user is also global administraor) Instead of the bes administrator.

I tried restarting, adding and deleting the user etc... Nothing helps.
