How to Report Old Guest Accounts and Their Membership of Microsoft 365 Groups (and Teams)

Microsoft 365 applications create lots of Azure Active Directory guest accounts. Here’s how to find old accounts and check their membership of Microsoft 365 groups. If you know the accounts that are old and stale and aren’t members of any Microsoft 365 group, you can consider removing them from your tenant.

How to Find Azure Active Directory Administrative Accounts Unprotected by MFA

Microsoft makes a strong case that all Azure Active Directory accounts should be protected with multi-factor authentication (MFA). That’s a great aspiration, but the immediate priority is to check accounts holding administrative roles. This post explains how to use PowerShell to find and report those accounts.

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.

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.

Office 365 Groups Naming Policy Now Generally Available

The Office 365 Groups Naming Policy is now generally available. The policy has taken nearly two years of preview to not get very far, but at least it’s now an official part of the service. Microsoft considers the naming policy to be an Azure Active Directory Premium feature. Many customers might think differently, especially because the naming policy must be implemented through PowerShell and can easily be mimicked through PowerShell. And of course, Exchange Online’s distribution list naming policy is free.

Azure Active Directory Still a Weakness for Office 365

The January 24-25 Azure Active Directory outage demonstrated once again how important AAD is to Office 365. Microsoft’s Post Incident Report tells us what happened to deprive 1% of the users in Europe of service. That doesn’t sound a lot, but you’d be mad if you were affected.

Azure Active Directory Feature Bans Custom Words from User Passwords

Making sure that Office 365 user (and administrator) accounts have good passwords is a never-ending task. A new preview feature in Azure Active Directory helps by ensuring that users can’t include common words specific to the organization (like its name) in a password. It’s another piece in the puzzle to frustrate potential attackers.

Teams Now Supports Dynamic Microsoft 365 Groups

The latest version of the Teams desktop and browser clients support the creation of dynamic teams based on dynamic Office 365 Groups.

Block Guest Members from Microsoft 365 Groups and Teams

By default, the Groups policy for an Office 365 tenant allows group owners to add guest users to group membership. You can block this access if necessary, but it’s probably not what you want to do as blocking brings guest access to a complete halt across the tenant.

Existing Guest Accounts and the Azure B2B Collaboration Policy

Office 365 E5 Accounts Now Keep Audit Log Data for 365 Days

Microsoft has updated its retention period for Office audit records from 90 to 365 days, but only for accounts with Office 365 E5 licenses. On another front, the problem with truncated audit records for Azure Active Directory events still persists.

Managing Guest Users in a Microsoft 365 Tenant

How many guest users does your Office 365 tenant have? And how many of those accounts are actually used? Given that many Office 365 applications now generate guest user accounts to facilitate external access to content, managing these accounts is a growing concern.

Org-Wide Teams Don’t Need Azure AD P1 Licenses

The prospect of having to pay for many Azure AD Premium P1 licenses just because you use an org-wide team is horrible to contemplate. But don’t worry. You don’t have to because the Teams developers look after membership updates for you.

Check Your Azure AD Accounts Before Adding Org-Wide Teams

Org-Wide Teams are a nice feature, but calculating their membership can be puzzling, as in the case of some perfectly valid accounts that were not added to a team. As it turns out, the error lies in Azure Active Directory.

LinkedIn Connects to Office 365

You can now connect Office 365 accounts to LinkedIn accounts (or block the connection at a tenant level). It’s a nice way to keep tabs on your LinkedIn contacts and find out what they’re doing with a simple click in an Office 365 people card.

How Microsoft IT Manages Microsoft 365 Groups

Details of how Microsoft IT manages its deployment of Office 365 Groups were discussed at the recent Ignite 2018 conference. It’s a good idea to write down the basic framework of your Office 365 Groups deployment, if only to understand how all the different policies and features fit together.

Security groups are often used to protect access to resources, but they can’t be used to control membership for Microsoft 365 Groups or Teams.

PowerShell is available to do the job, and as it turns out, it’s not too difficult.

What that BOXServiceAccount Does in Office 365

Records featuring an account called BOXServiceAccount appear in the Office 365 audit log. Not much information is available about the account, but it’s all OK because it’s used to assign administrative roles to Office 365 accounts.

When Things Go Wrong in the Cloud It’s Hard to Look Where for Help

An outage in a U.S. datacenter on September 4 caused problems for Azure Active Directory with a ripple effect on Office 365. It’s a good example of how cloud services depend on each other, so when one fails, another has problems.

Using Dynamic Office 365 Groups with Teams

Some say that Microsoft Teams doesn’t support dynamic Office 365 Groups. Well, I couldn’t find anything formal on the topic and the teams that I have configured to use dynamic groups work well, so what’s the real scene? As it turns out, Microsoft is still working on the feature.

Office 365 Gravtar

A recent post by MVP Mark Vale describes how to use synchronization transformation rules in AADConnect to change the last name, first name format (for example, Smith, James) for display names to a more user-friendly first name last name format (our example becomes James Smith) for accounts as they synchronize to Azure Active Directory from an …
