Certainly did - that configured ok.
Basically, I have 6 Exchange Servers, 3 5.5 and 3 2000.
I'm not even sure to be honest if the problem is with Arcserve now...
One of the 2000 servers can be backed up fine via arcserve, the other 2 cant due to the problem i posted above, but surely when I create a backup job and I browse that server I should see 'MS Information Store' and then be able to expand this to see storage groups etc. instead I can only see 'MS Exchange Server' without being able to expand it - as though it thinks it's a 5.5 server and not 2000 maybe ???
Anyway, even if I do just select this and start the job it fails, giving me the error - E8552 and E8563 - all of which I looked up with little success !!!
Thanks for ur time !!
