Troubleshoot the Todoist and Outlook integration

If you’re trying to set up the Outlook add-in, but the Manage Add-ins option isn’t visible, you’re either using a corporate account where your administration disabled the installation of web add-ins, or you are using an account type that isn’t supported by web add-ins, like an IMAP or POP3 account.

Due to security restrictions that Google places upon apps, it's not possible to use Google login to authenticate your Todoist account. As a workaround, add a password to your Todoist account, and use login via email and password to authenticate. 

When clicking an Outlook email in a Todoist task, your default web browser opens a new tab automatically where you can view the email. It's not possible to view the email right in Outlook.

If you’re signing in to the Outlook add-in with your Google account, you may see this error message:

This browser or app may not be secure.

To resolve this, open Outlook web app and log in with your Google account.

If you’re using the Outlook desktop app or mobile app, log in with your Todoist email address and password instead. If you don’t have a password, here’s how to add one.

When using the Outlook Add-in, you may see this error message:

Outlook plugin is unverified and needs admin approval.

To resolve this, contact your network admin to grant access to the Integrated Apps option in the O365 admin portal. Then, have them select Add Apps and search for Todoist for Outlook.

From there, your network admin can choose to deploy the integration either for all users or for specific users. They’ll need to agree to the required permissions:

• Read your mail
• Sign you in and read your profile
• Maintain access to data you have given it access to

If you're using Todoist on a company network, and you see an error that starts with:

Something went wrong

AADSTS: error description

Contact your IT department or administration and provide the exact AADSTS error code (for example: AADSTS50158) to help with troubleshooting. Here's a full list of Microsoft AADSTS error codes.

The Outlook add-in needs your permission to access the Microsoft Graph API to fetch a robust link to the email. This link is attached to your Todoist task. This is the only time Todoist requests your permission to access the API, nothing else. 

If you’re using the Outlook add-in, and it keeps prompting you to log in to your Microsoft account when clicking the link, the email has likely been moved, archived or deleted.

To get access to an email that has been moved, archived or deleted, the integration will prompt you to log in to your Microsoft account and grant permission to use the Microsoft Graph API. After granting permission, the email link will then work, even if the email has been moved, archived or deleted. 

If you choose to log out of your account in the add-in settings, you’ll also log out of both your Todoist account and your Microsoft account.

If you’ve used the Outlook add-in to create a task, and then moved the linked email out of the folder it was saved to, the link becomes invalid and you won’t be able to use it anymore.

To resolve this, use the add-in to create a new task from the email’s new location. We recommend deleting the old task with the broken link in Todoist.
