Tag: Azure AD Guest Accounts

It’s easy to invite people to become guest users in a Microsoft 365 tenant, but some of the invitees never accept the invitation. Perhaps they don’t need to redeem the invitation to do work or maybe it’s because they don’t want to. In either case, Azure AD guest accounts with unredeemed invitations can accumulate and become stale. In this post, we discuss how to use PowerShell to find and remove those stale accounts in a safe manner.

Azure AD Guest Accounts have a habit of becoming stale or obsolete as time progresses. Guest accounts created to share documents or to be a member of a long-forgotten team or group remain in Azure AD until someone comes to clean them up. This article explains how we refreshed a popular script to use cmdlets from the Microsoft Graph PowerShell SDK to report guest accounts with different degrees of staleness.

Getting a new device means that some work must be done to ensure that apps work. This article explains how to add QR codes to the Microsoft Authenticator app so that the app has the credentials to respond to MFA challenges. We cover how to get QR codes for Azure AD accounts and how to do the same for guest accounts in other Microsoft 365 tenants.

The Azure AD PowerShell module allows guest accounts to sign into target tenants and update their account photo there. The Microsoft Graph PowerShell SDK includes a cmdlet to do the job, but it doesn’t work when connected to a target tenant. Permissions are the reason why, which is what we explain in this article.

Despite the advent of shared channels in Teams and the wonders of Azure AD Direct Connect, the chances are that Azure AD B2B Collaboration (Azure AD guest accounts) will remain the predominant method for external collaboration for the immediate future. That’s not so bad, as long as you maintain good guest hygiene!
