Surprisingly I can't find much about this. Basically, in Outlook 2013 (or Windows Live Mail 2012 too), if I have more than one account (an IMAP and exchange, in my case), I don't always get new mail notifications for the IMAP account. Exchange works fine (i.e., new mail comes in, I get an alert). I'm talking specifically about IMAP and the "push" functionality.
The only way I seem to get alerts for IMAP alerts is if I leave the inbox for the IMAP account selected. From then on, I get alerts for my IMAP account, even when outlook is minimized.
The only program that seems to consistently give me new mail alerts if the built-in Windows 8 Mail app. The only thing I don't like about that is I don't get an email notification in the task bar (in case I miss the alert). My goal is to use Outlook.
Is there something I can do in Outlook to more reliably get new email notifications for IMAP accounts? I've also tried a Gmail account and have the same behavior, even on multiple machines. Thanks.
