I am using EWS Managed API 2.2 and it does not show the Exchange version 2016 in its enumeration. I can see the versions upto Exchange 2013. So how can I connect to Exchange Server 2016? Is the API, yet to be updated from Microsoft or do I need to use any other API's to connect to Exchange 2016 ?
Exchange provides the following authentication options for you to choose from: OAuth 2.0 (Exchange Online only) NTLM (Exchange on-premises only) Basic (no longer recommended)
On the Exchange Server hosting the Exchange Web Services open the Internet Information Services (IIS) Manager administrative tool. Navigate through to Server | Sites | Default Web Site | EWS. Select the Authentication icon from the feature view. Ensure that Basic Authentication is enabled.
“We will also remove the ability to register new apps in Azure with EWS permissions starting September 30, 2022. Apps registered before this date, any API not mentioned in this, or subsequent announcements, will not be impacted.”
It will connect just fine. You don't need to set the version to match the server, you set the version to indicate the lowest level of service you support.
