Microsoft is retiring Exchange Web Services (EWS)

The Exchange Sync shutdown is coming.

Microsoft is shutting down Exchange Web Services (EWS) — the original sync path many existing business applications still rely on. Exchange Sync Bridge keeps your software connected to Microsoft 365, with no vendor update required.

01 // PRIVACY

Your Exchange data is not stored

Exchange Sync Bridge passes requests between your software and Microsoft 365. It does not retain your calendar, contact, task, or mailbox data.

02 // AUTHENTICATION

No user passwords collected

Sign-in runs through Microsoft itself. We never see or store user passwords for anyone in your organization.

03 // SETUP

Ready in minutes

Cloud-hosted setup can usually be completed in minutes. Your existing software keeps using the Exchange Sync feature it already has.

Quiet Handoffs Behind The Scenes

Your existing software keeps using its familiar Exchange Sync feature. Exchange Sync Bridge handles the Microsoft 365 connection for it, no changes to the software you already depend on.

MICROSOFT 365
Response returned in the expected format

Built for existing software that has not been updated for Microsoft's newer sync technology, and for firms that cannot afford to wait on the vendor.

Initial Cutoff

Microsoft begins blocking the legacy Exchange Sync path used by many existing business applications.

Apr 1, 2027
Final Cutoff

Some organizations may extend access with specific Microsoft 365 admin changes, but this is the last date it will work.

After that, software still working perfectly well will simply stop syncing. Exchange Sync Bridge is designed for that gap.
