hi team, hope you are well.
whenever an agent uses the osticket scp to post a reply on a case, if a security group appears on the thread as a collaborator 'Microsoft outlook' will post:
Delivery has failed to these recipients or groups:
Call Center Leaders (ccleaders@domain.ro)<ccleaders>
Your message couldn't be delivered because delivery to this group is restricted to authenticated senders. If the problem continues, please contact your email admin.
Diagnostic information for administrators:
Generating server: MAIL2.domain.local
ccleaders@domain.ro
Remote Server returned '550 5.7.133 RESOLVER.RST.SenderNotAuthenticatedForGroup; authentication required; Delivery restriction check failed because the sender was not authenticated when sending to this group'
Any suggestions please?
