Hello All,

        I am having a problem when trying to restore old Exchange Backups.  We
have built the recovery server, installed and configured Exchange 5.5, and
installed and configured TDP for Exchange V1.1.  This version was installed
because this is what was used to perform the backup.  When the GUI is started
and the "Show All" button is clicked, all of our full and incremental backups
appear.  We select the full backup we want to restore and the agent contacts the
TSM server, mounts the proper tape, and begins to send data.  However, as soon
as it starts to send data, the restore fails with the following error:

Exchange Event Service
Exchange Information Store Service
01/08/2002 11:36:14,RESTORE(GUI) - Database: IS, Type: Full, Size: 22G, Actual
bytes: 0, Secs: 0.00, Kb/Sec: 0.00, Exchange Server:

PJMNT11, TSM Server: PJMNT24, Status: ACN4226E -- Exchange Error: ACN3516E -- An
unknown Exchange API error has occured.

Has anyone experienced this error?  What are the possible causes?  What are the
possible solutions?  Can I use TDP V2.2 to restore these backups?  If, so how?

Thanks in advance,

Sean
