Users are not able replay from their email

[Vikas Thorat]

Hello Team,

Our users are not able to replay tickets via there email. we have email set 

Example : jira@abcd.atlassian.net . 

Scenario: when user get notification from Jira default email address to there  own email box and than they try replay from email itself and replay not got updated in JIRA.

I found something as new to Jira admin. its seem that Microsoft basic authentication is no longer supported . can you please suggest solution asap!!!

Cheers,

Vikas
