Hi, 

I recently installed Outlook for Mac 2011. I have 3 email accounts - imap (Yahoo & Gmail) and a personal email with Go Daddy. 

I have 2 problems:

1. Outlook keeps downloading old emails, but only for my Yahoo account. I tried re-setting the "check for new mail" time to 30 minutes but this didn't fix it. I want to keep my messages on the server as I need to check my mail across different devices.

2. Outlook intermittently requests my password for both Yahoo and Gmail. When I enter it, the mail comes through so I'm confident it's not an incorrect password issue.

I actually have product support with Microsoft but using the service was as frustrating as the email issue itself (the guy asked lots of questions, said he would call me back and then didn't). 

Does anybody have a solution? I'd be really grateful for any help.

Thanks,

Jo
