Fix Office 365 Hybrid Configuration Wizard Sign-In Button Not Working
Question details
The user is unable to proceed with hybrid setup because the Microsoft 365 Exchange Online Sign-in button in the Hybrid Configuration Wizard is unresponsive.
- Product
- Microsoft Exchange Server
- Device & OS
- not provided
- Scenario
- Configuring a hybrid setup between on-premises Exchange 2013 and Microsoft 365 Exchange Online.
- Observed behavior
- Clicking the Microsoft 365 Exchange Online Sign-in button produces no action, no authentication prompts appear, and no related errors are logged in the Event Viewer.
Ensure you have Enterprise Administrator credentials for your on-premises Exchange Server and Global Administrator rights for the Microsoft 365 tenant before running the wizard.
Verify Prerequisites and Update Hybrid Configuration Wizard
Ensure your server environment meets the latest Microsoft requirements, specifically TLS 1.2, and use the most recent version of the wizard.
Microsoft 365 modern authentication requires TLS 1.2 to be enabled on the server. If TLS 1.2 is disabled or if you are using an older browser configuration, the sign-in pop-up will silently fail to launch.
Check your Windows Server registry settings and ensure TLS 1.2 is fully enabled for both client and server protocols.
Ensure your server's default browser (such as Microsoft Edge) is updated and not blocking pop-ups. Internet Explorer's enhanced security configuration often blocks the modern sign-in prompt.
Uninstall the existing Hybrid Configuration Wizard from your server. Log in to the Exchange admin center (EAC) and download the latest version directly.
Review Wizard Logs for Hidden Errors
If the user interface provides no feedback, the backend logs often capture the exact point of failure or blocked connection when clicking the sign-in button.
Consult Microsoft Exchange Management Forums
For complex, environment-specific configurations where standard troubleshooting fails, post your specific scenario to dedicated Microsoft engineering forums.

Frequently Asked Questions
Why does the Hybrid Configuration Wizard sign-in button do nothing?
This is typically caused by the server missing TLS 1.2 prerequisites, strict browser security settings blocking the modern authentication pop-up, or using an outdated version of the wizard.
Where are the diagnostic logs for the Exchange Hybrid Configuration Wizard stored?
The logs are located in the user's AppData folder. You can access them by navigating to '%appdata%\Microsoft\Exchange Hybrid Configuration' on the server where the wizard was run.
Does Exchange 2013 support the latest Microsoft 365 hybrid setups?
Yes, but it requires the server to be running the latest Cumulative Update (CU) for Exchange 2013, have TLS 1.2 properly configured, and use the most recent release of the Hybrid Configuration Wizard.
