I have 2 accounts in Outlook 2000. I believe it is setup exactly the same on this machine as on my other Windows XPP machine and they both use Outlook 2000 SP-3. On this one after switching between accounts twice Outlook will no longer check for new or send mail without at least logging off and back on. Where should I look to correct this because I know on my other machine I never did and still don't have this problem? I can go back and forth between accounts as often as I wish.
