SYMPTOMS
When you try to reconnect to a mailbox under Microsoft Exchange 2000 Server, you may receive the following error message:

The mailbox /O= /OU=your_site/CN=RECIPIENTS/CN=

The specified value is used by &quot;.

Facility: Exchange System Manager

When you try to reconnect to a mailbox under Microsoft Exchange Server 2003, you may receive the following error message:

The legacyexchangedn value is already being used by /O= /OU=your_site/CN=RECIPIENTS/CN=

Facility: Exchange System Manager

CAUSE
This behavior can occur because the mailbox in this information store attempts to connect to a user object in Active Directory that has the same Simple Mail Transfer Protocol (SMTP) address as a mail-enabled contact that already exists in Active Directory.



RESOLUTION
To resolve this behavior, remove the mail-enabled contact that has same SMTP address as the mailbox that you are attempting to reconnect. To do this, perform the following steps:
 * 1) Click Start, point to Programs, point to Administrative Tools, and then click Active Directory Users and Computers.
 * 2) Expand the Organization name, and then click the Users folder.
 * 3) Right click the mail-enabled contact displayed on the left, and then click Properties.
 * 4) Click the E-mail Addresses tab and remove the appropriate SMTP address from the list.
 * 5) Click OK, and THEN close Active Directory Users and Computers.
