Hello

For Exchange Online worldwide endpoints:

https://learn.microsoft.com/en-gb/microsoft-365/enterprise/urls-and-ip-address-ranges?redirectSourcePath=%252fen-us%252farticle%252fOffice-365-URLs-and-IP-address-ranges-8548a211-3fe7-47cb-abb1-355ea5aa88a2&view=o365-worldwide

instead of use of domains and names for example ( *office.com , outlook.office.com) can we use Ip address only?

Thanks

    It's recommended to use the URLs, as IP ranges can change at any time.

    Outlook.office.com is pointed to an IP ranges rather than a static IP address. So, you cannot use a IP address to replace the FQDN. If my understanding is wrong, please point out and provide detailed information so that we can provide further solutions.
