Microsoft has officially announced the retirement of Exchange Web Services (EWS) API, effective October 2026.
At Riva, we have been proactively preparing for this transition over the past three years and have developed a Graph connector to support the core functionalities of Riva Sync. While some less commonly used features are still being finalized, our priority remains ensuring a seamless and uninterrupted sync experience for our customers.
To ensure a smooth migration well ahead of the deadline, we have established a phased approach and will be proactively reaching out as we onboard customers into each phase of the transition.
- Cloud Customers – Migration scheduled for Q2-Q4 2025
- On-Premise Customers – Pre-production validation begins September 2025, with full migration targeted for February 2026
This is a top priority for our team, and we will be working closely with you throughout this process. Please stay tuned for further communication, including detailed migration timelines.
To ensure the right stakeholders receive timely updates, let your account manager know if additional members of your team should be included in these communications.
