Mixed Exchange 2007 or Exchange 2010 Environments with Exchange 2003 not Supported

Managing both Exchange 2003 and Exchange 2007 or Exchange 2010 in a mixed Exchange 2003/2007/2010 environment is not supported with this release.  If you have updated your Microsoft Active Directory schema by running the Exchange 2007/2010 Setup tool in either your domain or forest, the im_ccs automatically identifies all Exchange servers in the domain as Exchange 2007/2010. If you want to continue managing Exchange 2003 servers only, you must first disable the Exchange 2007/2010 functionality using a registry key on the machine(s) running the im_ccs services.

If you do not apply this change, the Connector Server is unable to correctly manage the Exchange 2003 functionality in a mixed Exchange 2003/2007/2010 environment.

To disable Exchange 2007 or Exchange 2010, perform the following steps:

1. Open the following registry key using regedit:

   HKLM\SOFTWARE\ComputerAssociates\Identity Manager\Provisioning Server
   

2. Add this new string value under the registry key:

   DisableExchange2007
   

3. Set DisableExchange2007 value to 1 or 2. The values are as follows:

   1 disables most Exchange 2007 functionality and treats all Exchange servers as 2000/2003.

   2 allows both Exchange 2003 and Exchange 2007/2010 with reduced functionality

4. Restart im_ccs service.

   Note: The ADS log will include a message about the status of the DisableExchange2007 setting.

The Provisioning Manager cannot create an Exchange 2000/2003 mailbox using an Exchange 2007/2010 specified Account Template.

When you have completed the above procedure and set the registry key value to 1, the following are disabled for Exchange 2007 and Exchange 2010.

• Mailbox creation
• Mailbox deletion
• Mailbox movement
• Mailbox Send-As permission management
• Mailbox Full Access permission management

If you have completed the above procedure and set the registry key value to 2, the following applies to managed Exchange 2000/2003 directories:

• Mailbox rights cannot be managed.
• Send-As permissions cannot be managed.
• When creating or modifying an Exchange 2000/2003 account template, clicking the ‘Mailbox Types’ button enables the Exchange 2007/2010 functionality. Mailboxes are not created on Exchange 2000/2003-based systems and no error message are returned. Do not click on the ‘Mailbox Types’ button if you want to create or manage Exchange 2000/2003 Mailboxes using that account template.

  If you do not apply this change the im_ccs service is unable to correctly manage the Exchange 2003 functionality.

Notes on setting the registry value to 2:

1. By default, Mailboxes are created as “Legacy Mailboxes”. For example, right clicking on an account and selecting ‘custom > create mailbox’ creates a Legacy Mailbox.
2. If you want to create Exchange 2007/2010 Mailboxes, set the mailbox type on the appropriate account template. If you do not set the mailbox type, mailboxes created by the account template are of type ‘Legacy Mailbox’.
