How to Fix Power Automate Not Recognizing Outlook Account During Reauthentication
Product
Power Automate and Outlook
Device & OS
not provided
Scenario
Reauthenticating an email connector in a Power Automate flow after a recent Microsoft Outlook password change.
Observed behavior
The Power Automate flow fails to recognize the entered email address. The Microsoft 365 Outlook connector appears available, but the personal Outlook.com connector fails to authenticate.
Before you start

Verify whether your email address is a personal Outlook.com account or a work/school Microsoft 365 account, as Power Automate uses completely different connectors for each.

Solution 1Recommended

Reset Microsoft App Permissions and Recreate the Connection

Removing Power Automate from your Microsoft account's app permissions forces a clean reauthentication process and clears corrupted token data.

When you change your Microsoft account password, cached authentication tokens in Power Automate can become corrupted. If you select the wrong connector type during the fix, the system will reject your email address entirely.

By clearing the existing app permissions manually from your Microsoft security dashboard, you force Power Automate to request a fresh, clean token.

1
Identify Account Type

Determine if your email is a personal account (Outlook.com, Hotmail) or an enterprise/school account (Microsoft 365).

2
Revoke App Permissions

Sign in to your Microsoft account portal (account.microsoft.com). Navigate to the Privacy or App permissions page, locate 'Power Automate' in the list of connected apps, and remove its access permissions.

3
Create a New Flow Connection

Go back to Power Automate and start a blank test flow. Add a new Outlook connector, carefully choosing either 'Outlook.com' for personal accounts or 'Office 365 Outlook' for business accounts.

4
Reauthenticate and Test

Sign in with your newly changed password. Once the connection is successfully established in the test flow, return to your original flow and update the broken connection step to use this new, authenticated connection.

Reset Microsoft App Permissions and Recreate the Connection
Connection Restored: By clearing the old app permissions, Power Automate is forced to bypass the unrecognized account error and establish a secure, updated link to your email.

Frequently Asked Questions

Why does Power Automate say my Outlook account doesn't exist?

This typically happens if you choose the wrong connector (e.g., using the Office 365 connector for a personal Outlook.com email) or if there is a cached authentication token conflict in your browser.

How do I update my password in a Power Automate Outlook connector?

Navigate to Data > Connections in the Power Automate left-hand menu, find your Outlook connection, click the three dots, and select 'Fix connection'. You will be prompted to enter your new password.

Can I use both Outlook.com and Office 365 Outlook connectors in the same flow?

Yes, you can use both connectors in a single flow, provided you authenticate each node with its respective, valid Microsoft account credentials.

What should I do if the 'Fix connection' prompt keeps failing?

Delete the broken connection entirely from the 'Connections' menu, clear your browser cache or open an incognito window, and create a brand new connection using the correct account type.
