Exchange ActiveSync

Question

I'm planning to create an application that syncs email, calendars and contacts between Exchange ActiveSync (EAS) and my own database. A few questions:

1. Are there any libraries or wrappers for EAS? (Preferably in Java)
2. What is the licensing cost? Microsoft does not explicitly provide a price anywhere that I've seen.

Thanks for any help.

Answer 1

(1) There are not many sample/libraries available. Here are your best bets:

• New to Exchange ActiveSync Development? (MSDN blog)

• Exchange Server Interoperability Guidance

• C# Code sample from MS

• Javascript implementation of EAS

If you're looking for Java specifically, buried somewhere in the Android mail app, which is open source, will be their EAS implementation which also might be helpful.

(2) Microsoft does not publish licensing costs and anyone who does license EAS is required to sign an NDA with respect to pricing which is why you will not see any info regarding pricing anywhere.
