Learn how to configure a Proxy server for Office 365.
- [Instructor] In this section, we will look at issues related to client connectivity to your Office 365 services, mostly looking at connectivity over the internet, because, of course, as we've mentioned several times, Office 365 is a web-based Cloud-based service. So, we'll start with this right here, Proxy Server Configuration with Office 365. This is one of those areas that may be the subject of a troubleshooting question if you are studying for the 346 exam.
So, if your network includes a proxy server that requires authentication, and many proxy servers do, then clients will not be able to make connections to Office 365 services. So, if this is the case, the admins are left with really two options and this is the big takeaway from this entire lesson here. Learning about these two options you have if a proxy server is denying a client access to Office 365.
So, here are the two options you have. You can either disable authentication entirely at the proxy server, or you can go in and selectively disable authentication for just Office 365 traffic. Now, the former solution, disabling all authentication, is much easier, much simpler, it requires much less administrative overhead. However, if you opt for the solution of selectively disabling Office 365 traffic, then you'll need to configure exclusions to certain Office 365 URLs and exactly what that list of exclusions is is a very lengthy list, and going through it here is certainly beyond the scope of this course.
So, remember what I said previously about the expectation that if you're an administrator you are expected to be resourceful at times, to look stuff up, you don't have to memorize each and every technique or instruction that you do when you configure an administrative task. The same certainly applies here. So, as we wrap things up, I do want to leave you with a reference that you should have handy if you ever need to refer to it later and go in and administer your proxy server to allow these Office 365 exclusions.
It'll look different depending on what kind of proxy server you are administering, whether it be a Windows proxy server or one by a different vendor. That's why it's a hard thing to even demonstrate here. So, here's the resource. I would just remember to do a search using your favorite search engine of Office 365 URLs and IP ranges. Now, there's no need to memorize the exact web address, but as you can see, I've pulled this up in a tab of Microsoft Edge.
This is what that article looks like if you go find that thing doing your search for Office 365 URLs and IP ranges. So, a little summary here about if your organization is using Office 365 and restricts computers from connecting to the internet. Now, here's your list of endpoints that you should include in your outbound, allow lists to assure your computers can successfully use the services of Office 365. So, what you're looking for here, and this is kind of a lengthy article, there's lots of links to additional information and the exact list of how your proxy server needs to be configured.
This is what you are looking for, this little section here, Office 365 Authentication and Identity. So, here's the explanatory text, to use services you must be able to connect to the endpoints marked as required below. So, expand to see the authentication and identity fully qualified domain names. So, this is what I was talking about, how that list is quite lengthy. So, this is the reference section for you. Just remember those two exam takeaways, you can either disable authentication entirely or disable these endpoints on your proxy server.
This course is ideal for any network administrator working with Office 365 and will serve as a valuable prep course for administrators wishing to learn the skills necessary to pass the exam.
