I'm trying to set up Service Desk to create incidents from emails. I got all of the inbound mail settings to work, but now it is creating incidents on its own. New incidents are being created that refer to previous incidents, for example, incident 761 says in its summary that incident 760 has been created. I don't know where these are coming from. I created a mailbox for service desk called "HelpDesk". The raise user on all of the new incidents is "HelpDesk Summary".
You need to set up ignore subjects in the mail action settings (doing this from memory but sure that is where they are!). Sounds like any automated replies are being logged.
Setup things like Out of Office, RE:
Those are already excluded. I just did an outbound mail test, which sends a test email with the subject "Touchpaper outbound mail test." It created an incident and then quickly created seven more incidents before I disabled the mailbox. The outbound mail test created incident 764. I resolved it and while I was doing that, 765 to 771 were created.
It turns out that I had to put the inbound email address for the HelpDesk account in the list of email addresses to ignore under action settings.
