If you signed up for Microsoft Advertising using Google Sign-In (or another third-party login like GoDaddy), you may run into trouble when connecting your account to Cometly. This guide walks you through how to fix it.
If instead you're seeing a "Need admin approval" message, that's a different issue. Check out our Microsoft Advertising Connection Troubleshooting article for that one.
Why Google Sign-In Causes This Problem
When you click "Sign in with Microsoft" in Cometly, it kicks off a standard Microsoft login process (called OAuth). This process requires your account to be registered in Microsoft's identity system called Entra ID (formerly Azure Active Directory).
When you sign up for Microsoft Ads using your Google account, Microsoft creates your ad account, but your identity lives with Google, not with Microsoft Entra ID. So when Cometly asks Microsoft to authenticate you, Microsoft doesn't have the credentials it needs to complete the connection, and it fails.
This is a Microsoft account setup issue, not a Cometly bug. The fix is getting your identity registered on the Microsoft side.
⚠️ Important: Simply creating a new Microsoft account or logging into ads. microsoft. com first won't fix this on its own. The account you connect with must be registered in Azure. The good news is it's free and only takes a few minutes.
How to Fix It
Step 1: Invite Yourself as a New Admin in Microsoft Ads
Sign in to Microsoft Ads at ads.microsoft.com using your usual Google sign-in
Go to Tools > Account Access
Click Invite User
Enter a different email address (this can be any email you have access to)
Set the role to Super Admin
Send the invite
Step 2: Accept the Invite and Create Your Microsoft Login
Go to your inbox and open the invitation email from Microsoft Ads
Click to accept the invite
Microsoft will prompt you to create a Microsoft account if you don't already have one tied to that email. Follow the prompts to set up a username and password.
Step 3: Register in Azure
Go to portal.azure.com
Sign in with the Microsoft login you just created
Complete the free Azure account setup
Navigate to Microsoft Entra ID (direct link) and confirm your account is registered
⚠️ Important: Without this step, the connection will still fail. Azure registration is what makes it work.
Step 4: Connect in Cometly
In the same browser, make sure you're signed in to Microsoft Ads at ads. microsoft.com with your new Microsoft login
Without closing that browser, go to Cometly and navigate to Integrations > Microsoft > Sign in with Microsoft
Microsoft should detect your active session and prompt you to authorize access without needing to sign in again
💡 Tip: Make sure you're using the same browser for both Microsoft Ads and Cometly. Microsoft uses your active session to complete the connection.
