EWS: Basic references

EWS Managed API

I've been working with EWS over the last few months and I've amassed a list of my favorite resources on this topic. I wanted to share this list with the hope that it would save someone time getting accustomed to the technology. One beginner tip- there is EWS and EWS Managed API. Sample code for the two are often listed next to each other and can be confusing for a new programmer. When you see EWS, think SOAP protocol (XML requests and responses), and when you see EWS Managed API, think C# code. The EWS Managed API is available as a NuGet package (Microsoft.Exchange.WebServices) for Visual Studio or by download link, here. Without further ado, I give you my favorite basic resources.

This is a pretty excellent high-level overview of what EWS is, how you can use it, and pointing you to more information on your area of interest.

EWS Best Practices
This is a list of links as well, but it will be updated by the author, whereas this list is not guaranteed to be. It's a great place to start as a beginning and return to when you have a better grip of what EWS is.

Get started with "Hello World!"
So you want to get a summary paragraph and jump right into creating a project? This is the place to start. Although, as soon as you're done, I recommend circling back to the EWS Best Practices 

EWS Managed API reference
This is for the when you're feeling adventurous and are ready to dive a little deeper into exploring the Microsoft.Exchange.WebServices namespace.

Links of Common EWS Questions
This is also, a list of links, but the common questions are here. Watch out, this is an old reference and some articles might be out of date. Once you have an idea of what your question is, or the answer is, check for an updated reference on the web.

Eventually you might be dealing with load, and this is a must read for learning about throttling for EWS in Exchange.
