Mixed Exchange 2007 Environments not Supported

Exchange 2007 is now supported with Identity Manager Provisioning Server. Managing both Exchange 2003 and Exchange 2007 in a mixed Exchange 2003/2007 environment is not supported with this release.  If you have updated your Microsoft Active Directory schema by running the Exchange 2007 Setup tool in either your domain or forest, the im_ccs automatically identifies all Exchange servers in the domain as Exchange 2007. If you want to continue managing Exchange 2003 servers only, you must first disable the Exchange 2007 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 environment.

To disable Exchange 2007 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 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 specified Account Template.

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

• 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 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 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'.
