EWS to Microsoft Graph Migration
– Upgrading Your Custom Programs to MS Graph
We support you in upgrading your own add-on tools from the discontinued Exchange Web Services (EWS) API to Microsoft Graph. Starting October 2026, EWS will end in Exchange Online – at that point, it will be necessary for your add-on programs or scripts, which you or long-gone developers programmed yourselves, to work with MS Graph or be replaced by other solutions.
Why Migrate Your Programs?
Many custom-developed tools (e.g., email archiving, attachment processing, or PowerShell scripts) rely on EWS and will become unusable by 2027. Without an update, functions in Exchange Online will fail. We adapt your code base – focusing on authentication, endpoints, and compatibility, based on our Exchange experience since 2007.
Our Service for Your Software
Individual Code Adaptation: Migrate EWS calls (e.g., Get-MailItems) to MS Graph (e.g., /me/messages).
For Custom Tools: Add-on programs, legacy scripts, or developer code from unreachable programmers.
Fast and Secure: Tests in your environment, including documentation.
Free Analysis: Send code snippets – we'll check EWS dependencies.
How to Get Started
Send code examples or a description of your programs by email to si+support@somebytes.net.
Free initial analysis and non-binding quote.
- After approval, we migrate – you receive the adapted, fully functional code.
