ExchangeOnlineManagement: stricter logon enforced from 2027-03-31, upgrade to 3.10.1
Summary
Microsoft plans to begin enforcing stricter logon requirements for the Exchange Online PowerShell module on 31 March 2027. Module versions older than 3.10.1 may fail to authenticate in certain interactive scenarios. Version 3.10.1 and newer continue to work normally.
What changes?
After enforcement, ExchangeOnlineManagement versions older than 3.10.1 may experience authentication failures in certain interactive authentication scenarios. Most at risk: PowerShell 7 with interactive authentication and Web Account Manager (WAM) disabled.
Affected
- ExchangeOnlineManagement versions earlier than 3.10.1
- Especially: PowerShell 7 with interactive authentication and WAM disabled
- Probably not affected: version 3.10.1 or later, Certificate-Based Authentication (CBA), WAM-based authentication, Windows PowerShell 5.x
Preparation and temporary exceptions
- Check the installed version with: Get-Module ExchangeOnlineManagement -ListAvailable
- Upgrade the module to version 3.10.1 or newer from the PowerShell Gallery.
- No other changes are required; enabling WAM is not necessary.
Check and complete
Upgrade the ExchangeOnlineManagement module to 3.10.1 or newer before 2027-03-31. Verify with Get-Module ExchangeOnlineManagement -ListAvailable.
Recommendation
Inventory admin workstations, servers and automation hosts that use the module and update them to 3.10.1 or newer well before 31 March 2027. Microsoft recommends the upgrade for all customers, including those using CBA or WAM, to stay compatible with future requirements.
