Hi , I have been struggling for a few weeks with our new BES Express 5.0.1 installation.

Whenever I try to activate a device the email including the .dat attachment remains in the users Outlook mailbox.

If I do a test with the IEMSTest tool, I get the results shown below in red. (CDO COM Exception fails).

The services originally were running under the domain admin account however I have changed the services to now run under the BESAdmin account however im struggling to get the Blackberry Mail Store Service to run under the BESAdmin account as this fails to start. This is still running as the domain admin account.

Im not sure how relevent it is but I have a lot of Kerberos errors in the logs.

Any help greatfully appreaciated.

Just to give a little information on the setup we use:
Windows EBS running in a ESXi Virtualised environment
BES Express is installed on the Exchange component of EBS
Blackberry's are are range of user owned devices

User: Opening message store using
/o=First Organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)

What version of Exchange are you using?

Obviously the part of this error that is the most useful is

Who cares, RIM will just change how they do Cert's again

Gary Collinson, you indicated that you "changed the services to now run under the BESAdmin account" so I'm hoping you followed KB04293-How to switch BlackBerry Enterprise Server service accounts - How to switch BlackBerry Enterprise Server service accounts . Once you've done that then I'd ensure you've set all the correct permissions as [MAPI_E_FAILONEPROVIDER(8004011D)]] typically means BESAdmin doesn't have enough rights and is being denied.
