Microsoft POP Support for Emails using OAuth 2.0

Issue Summary

JSD currently only supports IMAP for Microsoft when authenticating using OAuth 2.0. Support should also be enabled for POP. 

Steps to Reproduce

1. Setup Microsoft client configurations in the OAuth 2.0 plugin
2. Navigate to Email requests within a JSD project
3. Select Microsoft and currently only IMAP is supported

Expected Results

Ability to also use the POP protocol. 

Actual Results

The drop down in JSD will only display IMAP - this has been deliberately disabled due the POP authentication protocol which Microsoft has adopted not being being supported in the Java mail library.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
