About switching to the Microsoft Mobile Services Protocol

Depending on your messaging service plan, this feature might not be supported.

If you use a Windows Live email account (for example, Windows Live Hotmail), you might be able to change the protocol for your email account from POP to the Microsoft Mobile Services Protocol.

The Microsoft Mobile Services Protocol adds support for near real-time delivery of email messages and reconciliation of opened and unopened email messages from your BlackBerry smartphone to your email account. If you have BlackBerry 6 or later installed on your smartphone, the Microsoft Mobile Services Protocol also adds support for the wireless synchronization of contacts from your Microsoft Mobile Services Protocol enabled account.These features are not supported by POP.

If you switch to Microsoft Mobile Services Protocol, you will not be able to perform some actions on the email messages that were on your smartphone prior to switching from POP, including replying to and forwarding email messages and viewing attachments.

You cannot return to using POP after you switch to the Microsoft Mobile Services Protocol.
