| Description | Unable to create object MBClean99:Alpha because it already exists. |
| Event Information | According to Microsoft: CAUSE: This problem occurs because an Exchange computer that has been reinstalled uses a backup Dir.edb file to retain the previous configuration of the directory. The Mailbox Manager object is still present in this Dir.edb file. If you run the Setup program to remove Mailbox Manager, the Setup program does not remove these directory objects. RESOLUTION: To resolve this problem, follow these steps: 1. Start the Administrator program. 2. Click the Add-Ins container. 3. Delete the following items: a. Mailbox Manager Object b. Extension for Microsoft Exchange Mailbox Manager for i386 c. Extension for Microsoft Exchange Mailbox Manager for Alpha. 4. Run the Mailbox Manager Setup program again. |
