As of 2026, there is no native "Sync" button between Gmail and Microsoft To Do. The most effective way to connect them is by using Zapier to automatically turn your emails into tasks.
- Go to zapier.com and sign in (or sign up for free).
- Click Create > Zaps in the left panel to start a new Zap.
- Click Trigger to define what kicks off this workflow.
- Search for and select Microsoft To Do as your trigger application.
- Click Sign in to connect your Microsoft To Do account.
- Under Trigger event, choose from the dropdown list.
- Click Continue with selected record to proceed with this setup.
- Select Gmail as the action app to send emails from your tasks.
- Click Sign in to connect your Gmail account to Zapier.
- Under Action event, choose your desired outcome.
- Click Continue to start setting up your email fields.
- After mapping the required fields, click the Continue button.
- Click Test & Publish to activate the automation.
