Petr,

This error indicates that TDP for Exchange,
actually the TSM API, tried to send some data
to the TSM server and the TCP/IP socket was closed or gone
for some reason.  If the TSM Server console/activity log
does not indicate why the session was closed, then it
could be a problem anywhere in between.
This is NOT specifically a TDP for Exchange or
Exchange error.

If you find this occuring frequently, you should
examine the TSM Server console/activity log with
more scrutiny and possibly get a network expert
involved to find out what may be going on.
Other folks on this list may have good suggestions
on chasing down "-50" TCP/IP errors.

Thanks,

Del
