I encounter The index user does not have a mailbox on the Exchange server error when attempting to add a Microsoft Exchange connection.

If you have verified that the index user does indeed have a mailbox on the Exchange server, you may still receive this error when attempting to add a connection.

The problem could be with an Exchange attribute named msExchQueryBaseDN.  This attribute can be used to limit a user’s scope of the global address book and address searches.  From an Exchange perspective, this is helpful for restricting access in environments consisting of multiple organizations or organizations with a substantial  number of mail-enabled objects.  By default msExchQueryBaseDN is empty, which will allow the user to search the entire domain.  However, if this attribute is no longer empty, it may be set to point to an organizational unit to which the index user is not a member.  Check with your Exchange administrator to verify the current setting for the msExchQueryBaseDN attribute, and to discuss changing it to allow the index user appropriate access.
