Hi to the community 
We have just last week started to get relay errors from Microsoft 365 when our support mail forwards emails to Jira. It has worked since last year, but suddenly both clients and us internally are getting a relay error. The mail comes through and the ticket is created, so why the error? Mostly it's a bother for clients since they don't think the ticket has been created.
We migrated to Jira from Halp last year, and things have been working.
We have conferred with our Microsoft 365 provider and they've confirmed that they see everything normal at our end.
What can I do to mitigate this in Jira? Anything changed recently that I have to look at?
Thanks!
/ Michael
