MX Update for Microsoft Services
If you are still using mail.global.frontbridge.com as your MX record
in conjunction with any of the Microsoft hosted e-mail services such as
FOPE (Forefront Online Protection for Exchange) it may be time to update
to mail.messaging.microsoft.com
Recently we learned that one of the IP addresses backing the
mail.global.frontbridge.com DNS record has stopped responding to
network requests. Upon further investigation turns out this legacy DNS
record is being deprecated and Microsoft asks everyone to use the newer
mail.messaging.microsoft.com record.
