If you are beginning your SBS 2003 migration, don’t forget to remove the mailbox management policy before you begin the migration. The details are here:

If you have Exchange 2003 or Exchange 2000 recipient policies that are only Mailbox Manager policies and do not define e-mail addresses (they do not have an E-mail Addresses (Policy) tab), perform the following steps to delete the policies:
In Exchange System Manager, expand Recipients, and then select Recipient Policies.
To verify that a policy is only a Mailbox Manager policy, right-click the policy, and then select Properties. The Properties page must not have an E-Mail Addresses (Policy) tab.
To delete the policy, right-click the policy, and then select Delete. Click OK and then click Yes.
If you have Exchange 2003 or Exchange 2000 policies that are both E-mail Addresses and Mailbox Manager policies (they have both the Mailbox Manager Settings (Policy) tab and the E-mail Addresses (Policy) tab), perform the following steps to remove the mailbox manager portion of the policy:
In Exchange System Manager, expand Recipients, and then select Recipient Policies.
b. Right-click the policy, and then select Change property pages.
c. Clear the Mailbox Manager Settings check box, and then click OK.

Do not delete any e-mail address recipient policies that have e-mail addresses that you still want defined in your organization. Exchange 2007 will use those policies when provisioning new recipients. |
