Emails not coming through to Jira support desk

[Tom Cairns]

Good Morning,

We have noticed new ticket requests from EXTERNAL recipients are not coming through to our Jira platform, they are in OWA of the support email address and that's it.

Also for older tickets, some replies are not coming through but they are being delivered as I can see them marked as delivered in our spam filter.

We have also noticed we get emails asking us to approve users? This is new to us, What access does this give them?

Any suggestions? 

Thanks

Tom

Tickets are coming through now but old replies are hit and miss

When we test the Mail handler we get this error if anyone can advise?
