Microsoft is phasing out access to the Client Access Rules in Exchange Online. They’ll do away with this means of controlling access altogether within a year.
Carauths are being replaced with Continuous Access Evaluation (CAE), which can apparently detect changes in access controls, user accounts, and the network environment as needed.
When suspicious activity is detected, or an account needs to be suspended, our users can make changes to their account as soon as possible.
Microsoft will retire CARs on September 2023, and they’re starting the transition process now. They’ll send message center posts to tenants via real estate plans, and users will have to plan for the changes.

When administering Microsoft 365, it can be difficult to determine which client connections have the access they need. One way is to create a policy and then configure restrictions on CARs.
Exchange Online Protection includes a variety of security features for your email data, including advanced threat protection and antispam filters. You can block malicious email attacks based on their unique characteristics and IP address, authentication type, and user property values, as well as the protocol running on their computer.
Exchange has powerful tools to give you the flexibility and control when it comes to access. It also offers snapshots in time that can help you get a sense of who’s using powerful features of Exchange. Not only does this help your organization see which systems are being used, but it also helps those people know where they’re supposed to be at with their use of those resources.
To fix a security hole, Microsoft releases patches for Windows that are widely needed by miscreants.
Microsoft is pushing to dispute what it considers to be its monopoly on email. With the new certification, users can pick between Microsoft 365 with Exchange Online and Office 365 without Exchange Online.
Microsoft wants users to switch to a more secure authentication method as soon as possible. If you have yet to update, this is your last chance before the deadline.
Patch Tuesday: Yet another Microsoft RCE bug under active exploitation
Microsoft announced a replacement CAE in January, touting its ability to react quickly on account revocations, disabling, or deletion; password changes; the detection of nefarious activity; and more. According to that blog post by Alex Simons, corporate vice president of product management for the Windows giant’s identity and network access division,
“When decrypted tokens are sent to client saf, they will automatically be routed back to Azure AD using existing mechanisms rather than requiring any manual user interaction,” Simons wrote. “Once a session is intercepted and the initial attempt to decrypt ended in failure, Azure AD will trigger an automatic redirection of all subsequent traffic.”
Session integrity determines a user’s authentication lifespan with no set session duration, we’re told.
Customers can now change passwords, control access, and configure other settings themselves by installing an agent on their computers. Additionally, the changes are adopted quickly throughout the organization according to Microsoft. Being able to make these changes at their own pace has organizational benefits for businesses of all kinds.
Cloud services on Azure have been updated to enable the availability of continuous access evaluation. This allows tier 1 and tier 2 or older accounts to be evaluated in a quick, efficient way. Critical events in the tenant can happen automatically without the use of Conditional Access policies.
Achooo! Don’t let these common events put you off.
Critical events can include a user account being deleted or disabled, a user password is changed or reset, or multifactor authentication is enabled for a user. There also are other events such as when an administrator explicitly revokes all refresh tokens for you, or when a rogue insider is detected by Azure AD Identity Protection.
Microsoft CAE helps ensure that workloads are processed correctly, and there are even features such as token revocation to help protect your workloads.
