We have been running our exchange server on a Windows 2000 server and just bought a new exchange server that is Windows Server 2003 R2.

We have about 12 people on our BES (which is located on a different server). What do we need to do to ensure that there is no service interruption?

Also, we did a test with a dummy account. We added the email box to our old exchange server. Made sure everything worked, email could come in and go out from Blackberry and Outlook. We then moved the mailbox to the new server. The BES shows that the Blackberry is on the new server but it will not receive or send emails. Everything still works in Outlook.

Same exchange version on both?

Yes. It is Exchange Server 2003 SP2 on both.

Did you make sure to add the appropriate BESadmin permissions to the new exchange server?

Use the following tools to help out your troubleshooting located at:

c:\program files\research in motion\blackberry enterprise server\utility\

From a command line run: iemstest.exe to ensure that BESadmin has permission to the user on your new exchange.

If successful you should get something like this back:


C:\Program Files\Research In Motion\BlackBerry Enterprise Server\Utility>iemstest.exe

Test completed successfully for USER.

If this comes back successful, try running handheldcleanup.exe from the same directory to fix BES pointers. After doing this, reload the user within Blackberry Manager and it should start working shortly. (Doing these steps help expedite the BES being updated, if you wait long enough it should update itself on the next scan by BES)

Everything worked except the creation of a new folder. I don't know why this failed but it did.

We ran the handheldcleanup.exe tool as well. Still not getting messages on the blackberry.

You are missing the Administer Information Store permission on the new Exchange server. Permissions have to be set on each individual Exchange Server.

Search BlackBerry Technical Solution Center for Exchange Permissions and you should find an article to help you check them.

I changed the setting on the one you mentioned to Allow and I changed the send as and received as to allow and I think its working. I am going to do some checking and then I will post and let everyone know.
