Error when you import a folder with MBX proxy addresses (263460)
The information in this article applies to:
- Microsoft Exchange Server 5.5 SP3
This article was previously published under Q263460 SYMPTOMS
When you try to import a .csv file into an Exchange Server folder with proxy addresses for mailboxes with an .mbx file name extension, you receive the following error message
The directory import from file Filename.CSV is complete.
X Error descriptions were recorded in the system's application event log.
The file pathcsv.err contains copies of all object descriptions containing errors.
Also, the following event is logged in the Application event log.
Event ID : 238
Source : MSExchangeDSImp
Category : none
Type : Error
Description :
The e-mail address specified for import object Useralias is not unique. MBX:1 has already been assigned to Address Book entry /o=<Organisation></ou=Site></cn=container></cn=<useralias>>
CAUSE
The import procedure does not work because you cannot use the same proxy address, of any type, for more than one recipient. In this case, the value of MBX:1 or MBX:0 is assigned to the first record in the .csv file and cannot be assigned to any subsequent entries in the .csv file.
STATUS
The folder import procedure cannot be adopted to include or exclude mailboxes from cleaning. You can achieve this only by using the Microsoft Exchange Server Mailbox Manager tool.
MORE INFORMATION
When you use the Mailbox Manager tool, you can either include or set a policy for each container to exclude a mailbox. Corresponding to the selection, the tool generates a proxy address for the corresponding mailbox of either type MBX:0 or type MBX:1. However, if you try to import a .csv file, it does not work and you receive the error message that is mentioned in the "Symptoms" section.
You can use Mailbox Manager to select mailboxes that you want to exclude from automated message deletion. With MBClean, there was a limit to the number of mailboxes that could be excluded. This limitation was caused by the way that the mailbox exclusion information was being stored. To overcome this limitation, Mailbox Manager stores the exclusion information on the mailbox itself. Mailbox Manager uses a custom proxy address of type MBX and adds this proxy address to each mailbox that is excluded. For example, if you use Mailbox Manager to exclude a mailbox named "Test," a proxy address of type MBX is added to the Test mailbox. When Mailbox Manager processes the mailboxes for cleanup, it ignores the mailboxes that have the proxy address MBX.
