Hello Support.
I need help figuring out why office 365 emails sent to vtext.com are significantly delayed. This seems to have started about April 2023. The error received is "Server at vtext.com (34.199.121.51) returned '450 4.4.317 Cannot connect to remote server ". Could someone please help me with this? I see many are having a similar issue on the Community but I see no solution posted.
Thank you.
