Azure Active Directory Risky Sign-In Policy Blocks Guest Access to Office 365 Tenants

Office 365 makes extensive use of Azure Active Directory guest accounts. Implementing a risky sign-in policy is a good idea, but it can have the unfortunate side-effect of suddenly blocking guest accounts that could previously access tenant resources. If blocks happen, they can only be lifted through administrative intervention in the guest account’s home tenant.

Creating a Dynamic Office 365 Group for Global Administrators

A reader asks if it’s possible to create a dynamic Office 365 group for global administrators. Well, it is and it isn’t. Azure Active Directory doesn’t give us the ability to execute the right kind of query to find global administrators, but with some out-of-the-box thinking, we can find a way to accomplish the task.

Office 365 Groups Naming Policy Now Configurable in Azure Active Directory Portal

The Groups section of the Azure Active Directory portal now includes a preview of a feature to configure the Office 365 Groups naming policy without going near PowerShell. Although those proficient with scripts and GUIDs will lament this sad reduction in standards, the normal administrator will welcome the chance to forget some obscure syntax.

LinkedIn Connector for Office 365 Uses Group to Control Users Allowed to Access Contacts

The LinkedIn connector for Office 365 now uses a group to control the set of user accounts allowed to connect their accounts to LinkedIn. It’s a good change because it makes the connection easier to manage. Even so, you might still need to use PowerShell to manage the membership of the group, especially if you want to add multiple people to the group at one time.

Eliminating Basic Auth for Exchange Online with AAD Conditional Access Policies

Exchange Online protocol authentication policies control what protocols a user can connect to mailboxes with, but it would be much better if we didn’t have to worry about some old and insecure protocols. Azure Active Directory gives Office 365 tenants the chance to clamp down on IMAP4 and POP3 connections and close off some of the holes that attackers try to exploit. Microsoft says that this can lead to a 67% reduction in account compromises, so that’s a good thing.
