Microsoft released out-of-band (OOB) Windows updates to fix a known issue that would cause Azure Active Directory and Microsoft 365 sign-in issues on Arm devices after installing the June Patch Tuesday updates 2022.
Today’s OOB updates are installed automatically through Windows Update and can also be downloaded and installed manually through the Microsoft Update Catalog (KB5016139 for Windows 10 and KB5016138 for Windows 11).
“Resolves a known issue that only affects Windows Arm devices and may prevent you from signing in with Azure Active Directory (AAD),” explains Microsoft.
“Apps and services that use AAD to log in, such as VPN connections, Microsoft Teams, and Microsoft Outlook, may also be affected.”
The full list of Windows versions affected by this issue includes multiple client platforms: Windows 11 21H2, Windows 10 21H2, Windows 10 21H1, and Windows 10 20H2.
According to a service alert issued to Microsoft 365 customers, some of the impacted scenarios include, but are not limited to, the following:
- Apps and services that use Azure Active Directory (Azure AD) to sign in
- VPN connections
- Microsoft Teams desktop
- OneDrive for Business

“This OOB update is cumulative. If you are using updates released before June 14, 2022, we recommend that you install this OOB update instead of the June 14, 2022 security update,” added Redmond.
“If you have previous updates installed, only the new updates in this package will be downloaded and installed on your device.”
Workaround also available for affected users
The company too shared a temporary solution on Friday’s first acknowledgment of this known issue, those who are unable to install today’s emergency update immediately will be able to continue using the affected products.
