This is causing us huge headache, it needs to be addressed, we have tried several rules on our exchange online to combat this but doesn't work either.
I had a short email conversation with support. Turned out Lansweeper mail rules apply only to new incoming tickets. Rules set at https://<yourserver>:<port>/configuration/HelpdeskEmail/ won't help.
Michael V. suggested ignoring mail on mailbox/server level. I logged to email with our Lansweeper mailbox credentials and added some rules to delete mail delivery error messages. So far this is working.
