Convert Microsoft Outlook add-in using EWS calls to have Outlook Mobile capability

Job ID: 30857934

Budget: £250 – £750 GBP

We have an existing Outlook Web add-in that forwards emails as attachments or calls an API depending on email header information.

This currently uses the older Microsoft EWS calls but we need these changing to the newer RESTful (or maybe even Graph) calls so that it's compatible with Microsoft Outlook Mobile.

The add-in needs to continue to be compatible with on-premise Exchange 2013 (or greater) and also Microsoft 365, for web Outlook, desktop Outlook and Mobile Outlook (iOS/Android).
