All my mail problems went away after applying sp1. we run exchange2000 fully patched the mapi client is outlook2000 sp1 and the account it a domain account with full mail rights. Scheduled jobs send mail but backup reports never made it and never generated an error. One problem I do have is when I try to use the contacts list instead of a regular email address i get a mapi resolution error from sqlserveragent. i.e. in outlook you can just use a name like john doe that doesn't resolve but john.doe@mynetwork.com does. I haven't setup reporting to groups yet ether so I don't know if it will send to outlook list yet or not.
