Greetings, Anyone experienced any issues with 0365 and the error below?
4.4.4 Temporary server error. Please try again later ATTR3 Retries are not successful, happens only with one specific /24 subnet and 0365 servers. Seems like a hard block, but never seen such an error, also Microsoft team has not aware about it as well o_O (at least my contacts). Would appreciate any ideas. Thanks. Sergey Syerkin
