Hi,
we support and maintain an application using EasyLink XOA 2.2 API based on SOAP. This API was originally developped by Premiere Global Services back in times when they merged MessageReach and Xpedite to offer an API for the operations actually offered by EasyLink MyPortal.
Since you seem to be the new owner of that stuff: What are the future plans for this API?
How long will XOA be supported? Are there plans to finally migrate to REST/JSON?
