I love using gmail through Google Sync on my iPhone because it supports PUSH through the Exchange protocol. See: https://www.google.com/mobile/sync

Essentially, they provide an Exchange compatible server through m.google.com.

I would like to setup Mail on OSX To use exchange as well, but have not been able to set it up properly.

  • Can you explain what kind of problems you have when you try to do it? At the moment, it seems that real Push is not available for Exchange or EAS connections.

No, you can't use Google Sync through Mail.app in Mountain Lion.

Google's exchange server m.google.com is not a fully implemented exchange server. It just implements the ActiveSync protocol which seems to be a subset of the exchange protocol for mobile devices.

  • The problem is with Mail.app, not Google Sync.

The problem is with Mail.app (not Google Sync), which does not suport ActiveSync. It uses Exchange Web Services instead, which must be pulled.

The options for push in Mountain Lion appear to be either use Outlook 2011, which does use ActiveSync, or configure Mail.app to use IMAP. GMail supports IMAP IDLE, which is the IMAP equivalent of ActiveSync push.

  • "must be pulled" meaning that Microsoft announced that it's deprecated? Jan 21, 2015 at 21:56
  • @Yar Meaning that the client must "pull" via polling, rather than "pushed" on-demand like ActiveSync. To my knowledge it's not deprecated, since it's alive and well in iOS. It seems like it should be possible to allow push-style web services via web sockets, but I have had trouble finding details.
