Microsoft 365 networking – Proxy Endpoints

For larger environments and/or infrastructures that have more complex network architectures, it can be important to split up the topic-related endpoints and distribute them to dedicated proxies.
With Microsoft 365 (as well as other Microsoft services such as Azure), the “best practice” statement is to define local brake out points so that the corresponding services can really function and be used optimally.

Recently, I had to create a corresponding endpoint list that serves the relevant services.

I have now decided to share this (non-exhaustive) list on my blog.

Disclaimer: This list is not complete. The endpoints are regularly adapted and changed by Microsoft. The following Technet articles serve as a reference:

• https://learn.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide
• https://learn.microsoft.com/de-de/microsoft-365/security/defender-endpoint/configure-network-connections-microsoft-defender-antivirus?view=o365-worldwide

As well keep in mind, that some of the Endpoints are used for multiple Services. I just added by some Endpoints a Service as a reference.

It should also be noted that the premium Microsoft 365 services such as Teams, Exchange, etc. will soon be migrated to the *.cloud.microsoft endpoint. This means that the list will tend to be shorter in future.
