This whole thing is very disappointing. I am about to see a potential client next week about an Exchange 2000-2007 migration but will be left in the position where I will have to recommend 2003 as the platform for Exchange 2007 and not 2008 and point out to the client that when this issue is resolved (!?) that there will be no upgrade to the newer OS but a full Exchange rebuild etc!
Does anyone know if its possible to backup from an Exchange 2000 server (I see 2003 should work above) but I doubt the client will want to pay for an Exchange 2003 license to upgrade their Exchange 2000 server just for an unsupported backup solution.?
I have a feeling that the client may make the decision not to go forwards with this at this time as I certainly won't be recommending DPM (another server etc) and third party backups cost significant in licensing etc and in my experince always create supportability issues etc! - not acceptable for a 120 user org...
