We have an issue where some emails are being deleted in Outlook and are not reaching the Jira issue.
This happens mostly for replies to an existing Jira issue.
The same thing will happen if the deleted email is manually restored from the Delete box and moved back to the Inbox. The email gets deleted after a few minutes but does not reach the Jira issue.
However, if the email is restored and we manually send it to the issue using the Jira Outlook Add-in, it remains in the Inbox and is not deleted.
Does anyone have any ideas on where we should start looking?
