MicrosoftMicrosoftPaul, We need to update our firewall, email security appliance and archiver appliance with these Exchange IP's in order for email to flow in and out of our organization. Adopting one of the unfortunate new methods we go here: https://endpoints.office.com/endpoints/Worldwide?ServiceAreas=Exchange&NoIPv6=true&ClientRequestId=b10c5ed1-bad1-445f-b386-b919946339a7 (using a different new unique GUID) and manually copy the section for *.mail.protection.outlook.com(ID 10) into notepad, remove the spaces, quotes, and commas (basically get it back to the NICE clean version that exists now at https://docs.microsoft.com/en-us/office365/SecurityCompliance/eop/exchange-online-protection-ip-addresses) so that we can paste it into our devices. While that new method solves that part of the equation, what it does not solve is knowing when those IP changes other than manually comparing them from time to time with what was published previously. As you can see it's bad enough that we have to go through many more steps to get the IPs, but add to that no time stamp further complicates things. HELP.
