- You deploy an account forest and a resource forest in a Microsoft Exchange Server 2013 environment.
- You configure a linked mailbox in the resource forest for a user in the account forest.
- The sAMAccountName attribute of the linked mailbox account differs from the sAMAccountName attribute of the user in the account forest.
- The user tries to access the linked mailbox through POP3.
For example, you create a user account in the account forest that is named Contoso\Pop, and create a linked mailbox in the resource forest that is named Fabrikam\Pop_Fab. In this situation, the user cannot access the linked mailbox by using POP3. However, if the linked mailbox is named Fabrikam\Pop, the user can access the linked mailbox by using POP3.
