The Easiest Way to Integrate with the Microsoft Exchange Email API

The Nylas email API powers apps with 100% of email service providers

Microsoft Exchange is one of the leading email service providers with hundreds of millions of active users and counting. To expand your reach and serve all your users, you’ll likely need to incorporate Exchange into your email operations. The Nylas Email API eliminates the headache of integrating with Exchange both on-prem and in the cloud, and gives you a dependable platform to future-proof your application.

Getting Started With the Exchange Email API

There are three ways to integrate Exchange servers: EWS, EAS, and IMAP. While EWS is the newest of all three protocols, it still falls short of the modern development standards you expect from mission critical tools like email. Nylas’ API sits atop Microsoft Exchange infrastructure, saving you 12-18 months of development time while delivering email functionality and reliability Microsoft can’t offer.

The burdens of building with Exchange directly

Development cycles are precious. They should be spent programming, not pouring through 1,000 pages of Microsoft’s specifications.

Nylas gives you production-ready, flexible code in the programming language you prefer, so you can engineer your email stack to your specifications.

Crafting Exchange protocols to fit your unique needs requires you to write business logic in WBXML so Microsoft’s API can wrap commands to send to Exchange servers. Once you invest the time wiring up functionality between your servers and Exchange servers, there’s no guarantee your application will remain upright.

Building directly on Exchange platform, you’re responsible for brokering negotiations between different versions of EAS and EWS. You have to keep track of server-side issues from intermittent processing issues, mailboxes that won’t sync, granting administrator privileges from Office365 and any number of fluctuating problems.

These problems are only magnified as you scale. With each new server you integrate, you build another dependency. Troubleshooting errors for new users syncing email accounts can turn EAS integration maintenance into a full-time job.

Nylas does things differently.

Scaling Exchange functionality on the Nylas platform

We built our own Exchange/ActiveSync integration to simplify the integration process for developers around the world. While Microsoft’s Exchange ActiveSync (EAS) was designed in 2003 for lightweight, mobile applications, Nylas is designed for the modern business and the modern developer.

The Nylas API handles billions of requests per month for companies in industries from ATS, to finance, to real estate, and the legal space. No matter the size, volume, or pace of your email integration, Nylas can support it.

EAS integrations are complex to build and maintain. Nylas eliminates that burden so you can get back to making your customers happy.
