We have an application which already using EWS managed API to connect to outlook emails via EWS. Currently, we are implementing authenticating through OAuth for both IMAP and EWS. For EWS, the API methods are working fine. However, when we are trying to connect using IMAP protocol, we are constantly getting the error "The response received from the service didn't contain valid XML" for FindItems method and others. URL for connecting to exchange service used is "https://imap.outlook.com".

Hence, wanted to if there is any way we can use EWS managed API for IMAP and if not what can be the probable solution for that.

    Based on your description, your issue is about EWS managed API and Exchange Server Development. However, Exchange Server Development is currently not supported in the Q&A forums, the supported products are listed over here: https://learn.microsoft.com/en-us/answers/products (more to be added later on).

    For the related questions about Exchange Server Development you can ask in here Exchange Server > Exchange Server Development.
