I have a several mail handlers, one for each project in Jira. When I test a Mail handler, I get no error only No messages were found in this mailbox. But the mailbox contains several emails. Some of the mail handlers are working. Issues are creating but the others aren't. They do not create or add comment to issues. What can I do? I have deleted these mail handlers and create them again but without any luck. All mail handlers have been working until now and nothing has changed in the mail handler configurations. The incoming mail server is working fine and is authenticated by Microsoft OAuth. Please advise.
Thank you.
Best regards,
Toby
