Replication delay solutions for a mailbox addition on Microsoft Exchange

Requesting a user account on Active Directory with mail status on Exchange might generate the error User does not exist.

This behavior is caused by replication delay. Exchange might not find the user account on a domain controller, if the account is created on another domain

The solution here is to target both the following operations to the same Domain Controller:

• Create user account operation.
• The Exchange operation, to either mailbox enable or mail-enable the user account.

To specify a target server use the Users Base Point DN on the Active Directory profile service form. The Base Point must contain the name of the domain controller.

Users Base Point DN: DC01/ou=Test,dc=MyDomain,dc=com.
