Jira currently only supports IMAP for Microsoft when authenticating using OAuth 2.0. Support should also be enabled for POP.
- Setup Microsoft client configurations in the OAuth 2.0 plugin
- Navigate to "Incoming Mail" in Application properties
- Select Microsoft and currently, only IMAP is supported
- Configure mail handler using Microsoft configuration and POP3 protocol
The newly configured mail handler is working properly and can be saved.
An error is being thrown on the "Test connection" step.
Currently, there is no known workaround for this behavior. A workaround will be added here when available
