Dynamics365 CRM – Unable to Login to Dynamics CRM

1. Check License and User Permissions: Verify that your user account has an active Dynamics 365 license and the appropriate security roles assigned. Without the right permissions, login will fail.
2. Clear Browser Cache or Try Incognito Mode: Cached data can sometimes cause issues. Clear your browser’s cache or try using incognito mode to rule out browser-related issues.
3. Ensure ADFS/SSO Configuration: If you’re using ADFS or Single Sign-On (SSO), confirm that your identity provider is correctly configured and that there are no issues with the authentication service.
4. Disable Browser Extensions/Pop-up Blockers: Extensions or pop-up blockers might interfere with the login process. Disable them temporarily and try logging in again.
5. Use the Correct CRM URL: If you’ve migrated or changed environments recently, double-check that you’re using the correct Dynamics 365 URL for your region or environment (sandbox, production, etc.).

If these steps don’t resolve the issue, checking the CRM’s system logs or authentication logs might provide more clues.
