HELP WITH DELAYED MESSAGES
We just switched from exchange on premises to 365. Now we are having problems receiving into owr accounts ex: user1@mydomain , user2@mydomain , , and this only happens from some domains for incoming ...
Nope, nothing wrong with the MX records. Anyway, I am guessing if there was something wrong with the MX records, then I would have problems with all domainsm, not just a couple,. Did you have a chande to look at the header I sent?
Has perhaps trying adding the sender IP (148.163.156.53) to the IP allow list in the connection filter settings located in the Exchange Admin Centre -> Protection -> Connection filter ?
It's worth a try.
