Re: [Networker] Exchange 2010 with NMM 2.4 and Networker 8.0

Hi Matt

It's a bit of a long shot, but are there any VSS Snapshots / shadow copies 
scheduled on the servers .... we used to have a similar problem backing up file 
servers and the regular scheduled VSS snapshots would come along and destroy 
any previous snapshot (normally the one created by networker) if the location 
that the snapshots were being held was at or near capacity

Good morning Stephanie,

     We were backing up Exchange 2007 just fine but when they moved to Exchange 
2010 and we switched to NMM 2.4 we started having issues.
