I’ve configured my Outlook.com account in Outlook 2013 as an Exchange Active Sync (EAS) account.

In a previous post you mentioned that unlike Outlook Hotmail Connector accounts, which syncs on a schedule, mail for EAS accounts in Outlook 2013 should arrive almost instantly (Direct Push).

This is indeed the case for a while but when I have Outlook open for a longer period of time, my Outlook.com account stops synching with Outlook and I have to press the Send/Receive button to get my new mail or restart Outlook

How can I prevent Outlook from breaking this sync and continue to collect my email directly from the server as it arrives?
