Sebastian,

For Exchange 5.5, look here:

http://www.microsoft.com/technet/prodtechnol/exchange/exchange55/support/chapt09.asp

If you still don't think Data Protection for Exchange
is working correctly, please call IBM support.

If you think this is a procedural question in regards to
Exchange itself, please call Microsoft support.

Thanks,

Del
