The user first authenticates and then Exchange Online will evaluate the Client Access Rules like an ACL, going down the priority list and stopping when it finds a match. One thing to note is that these do not help with brute force attacks. Use your imagination, these things are pretty cool. While this is cool, you can also use these rules to not allow specific networks as well should have the need, as well as a bunch of other situations. The most common use case I have seen for this is restricting access to just the corporate/company networks. They let you define the conditions based on various properties of a client. You can prevent clients from connecting to Exchange Online based on their IP address, authentication type, and user property values, and the protocol, application, service, or resource that they’re using to connect. Client Access Rules in Exchange Online are rules that you can use to control which client connections are allowed and not allowed to access your Exchange Online organization.

Client Access Rules are like mail flow rules (also known as transport rules) for client connections to your Exchange Online organization. The more familiar you get with the tool, the more you can tweak certain fields to increase the accuracy of the predicted bandwidth requirements. Microsoft gives a pretty good definition so I’ll just throw that at you because I’m lazy:Ĭlient Access Rules help you control access to your Exchange Online organization based on client properties or client access requests. Exchange Client Network Bandwidth Calculator can be a helpful tool in designing and implementing Exchange server solutions both on premise and Office 365. I receive client version 357.1 for all checked mailboxes, and this is not Outlook version. If I run: Get-LogonStatistics -ideintity JSmith Select UserName,ClientVersion,LastAccessTime,ServerName. Client Access Rules give you a lot of control over who can access Exchange Online from where. But how we can find outlook client versions connected to Exchange 2010.
