Just set up the Mail app in Lion, it worked fine for a few days but now I'm having problems. I use Gmail for personal email and another webmail for work. Had always used web interfaces before, but now I need offline access to email. Set up mail with both accounts. Many work people use my personal address, so I move work emails sent to my Gmail inbox into the work inbox. This worked fine for the first few days, but now the work account seems to only check for mail when I start the app. I can send myself an email to the work account, or move a mail from the personal to work account, and they don't show up. When I click "check mail" it gives me the little beep telling me that there is no new mail. Gmail account does not have this problem, pulls emails just fine at any time. I must quit Mail and restart for the new mails to show up in my work inbox. When I visit the web interface they show up there just fine. Settings for Gmail and work accounts are identical, and the program is set to check for new mail every 5 minutes. Any ideas on what happened and how to fix it? Thanks!
