We recently upgraded our email provider to Exchange Online and switched all the DNS and MX records accordingly. After about an hour I did a test email, and it went to the new server like it was supposed to. However, the second test email went to the old server and every email since then. I've checked with whatsmydns, and everything is pointing to the new server correctly.
After a bit of google research, I found out that MX records are often cached and typically don't follow the TTL expiration. So is there any way to forward all emails sent to the old server to the new server while we wait for the DNS servers around the world to get the memo?
Thanks,
