I have minemeld mining O365 address for my PA's. Moved to the new API as well.
I have a hybrid Exchange setup.
I have moved some mailboxes up to the cloud
What I have found recently is mail stops flowing
I have a rule that basically say
MS Public IPv4 to my beachhead port 25 smtp
O365 attempts to talk to me and gets blocked.
I check the src address and its in the EDL range.
If I clone the rule and place it below it and then commit and push (from panorama)
once the push has finished it starts to work . same src ip and it matches the original policy.
almost like there is a TTL on the edl ip addresses
Now I have the EDL set to refresh at 6am. guessing I can change that to every hour ?
Any one else had issues
