We've got an IMAP mail server set-up in JIRA. It's configured on our own onprem Exchange 2016 server.
I made a new mail handler to read mails from a feedback address with the purpose of automatically creating new bug reports for a software project.
The default reporter is the project lead on the software project that was created for the issues. So the account should have rights to create issues in the project.
The mail address we have for the feedback is on O365, while the IMAP mail server is onprem. So as a test I've made a shared mailbox on the onprem exchange.
But during the test in the mail handler I get that the test is successful but that there are no mails in the inbox, while it's certainly the case. The mails also aren't older than 7 days.
Someone got an idea what the problem might be?
