Blackberry Enterprise Server not working on Exchange 2007

I have a BES server working with Exchange 2003.
Recently, I've setup a new Exchange 2007 and plans to migrate the users over to 2007.
However, after I migrate myself from 2003 to 2007 server, the Blackberry services fails to work:
meaning, my emails are not forwarded to my BB, and I cannot send emails out from my BB.
Is there any other steps required for this?

Go into the Bes settings and see if it is still pointing to the old server. It probably needs to be updated.

The Blackberry Manager updates that my mailbox is now on the new Exch. Server.
For this, do I just migrate the user between the Exchange or do I need to perform some settings on the BES?
My BES Server is 4.0.2
Tony GiangrecoCommented:
Your users should already be on exchange 2007. if that migration process is complete for all mailboxes, you should complete the migration by removing 2003 exchange from the envorinment.

One safe test is to shut that server down, restart the BB server and see what happens.

Mine is the Small Business Version.
Am I entitled to the upgrade?

For me, I am unable to remove the Exchange 2003 because I can't ensure that 2007 well with BES thus it is still on.

For you, do you need to perform any configuration on your exchange server?
Tony GiangrecoCommented:
You should complete your migration from 2003 to 2007 which includes pulling the exchange 2003 server out of the network. Until you do that, you will probably have a problem with Bes. I have two clients with networks 1-2003 and 1-2007 and DESX. Both run fine.

The recnfig would be in BES after you complete the migration process.

I dont think the issue is with BES or migration is required... You may have to install " Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1" both on Exchange as well as BES

Please refer BES article below

This may or may not work. I know when I move users between information stores, I have to run the cleanup utility. The same might work in this instance.
Mailboxes moved over to Exchange 2007 will no longer be able to send and receive email via their Blackberry Handsets. In order to resolve this problem extended permissions need to be set on the Exchange 2007 servers. The following Power shell commands were run to set the desired permissions.
This command sets permissions for the Production Blackberry service acocunt

•      add-exchangeadministrator besadmin -role ViewOnlyAdmin

This command sets permissions for the development Blackberry service account

•      add-exchangeadministrator bbadmin -role ViewOnlyAdmin

To verify the required roles are present.

•      get-exchangeadministrator | Format-List

 The following commands set the required Send-As and Receive-As permissions to the BesAdmin Account

•      get-mailboxserver mbx-exchange | add-adpermission -user besadmin -accessrights GenericRead, GenericWrite -extendedrights Send-As, Receive-As, ms-Exch-Store-Admin

•      get-mailboxserver | add-adpermission -user besadmin -accessrights GenericRead, GenericWrite -extendedrights Send-As, Receive-As, ms-Exch-Store-Admin
The following commands set the required Send-As and Receive-As permissions to the BBAdmin Account

•      get-mailboxserver mbx-exchange | add-adpermission -user bbadmin -accessrights GenericRead, GenericWrite -extendedrights Send-As, Receive-As, ms-Exch-Store-Admin

•      get-mailboxserver | add-adpermission -user bbadmin -accessrights GenericRead, GenericWrite -extendedrights Send-As, Receive-As, ms-Exch-Store-Admin

To verify the required permissions are present, execute the following command.

•      get-mailboxserver mbx-exchange | get-ADpermission -user besadmin
•      get-mailboxserver mbx-exchange | get-ADpermission -user bbadmin

this information was copied from the the last Exchange 2003 - 2007 transition I performed that had BES so should apply to you.


i guess you may have to further diagnose the issue and come up with exact issue because Blackberry may not work for multiple reason... Please provide more information

Check for eventlog, blackberry logs, status on blackberry device and server for the specific user hosted on E2K7

OK I've gotten help from RIM's engineer for the past 5 days.
The issue is, BES 4.0.2 does not support Exchange 2007.
Only BES 4.1.6 onwards support Exchange 2007.
As my company did not budget for this, we decided to switch to BES Express 5.0.3 and it is now working fine.
Thanks for the help!
