Solution 1Recommended

Request Assistance in Microsoft Support Forums

Because OAuth and connector issues are often related to backend service configurations, reaching out to dedicated Microsoft forums is the most effective way to resolve them.

Power Automate connector failures often require service-specific troubleshooting from Microsoft specialists who can look into tenant-level permissions or temporary service outages.

Navigate to the support forums

Open your web browser and visit either the Microsoft Q&A portal or the Power Platform Community forums.

Create a new support thread

Provide connection details

Describe your issue clearly. Include the connector being used (Outlook), your account type (personal or work), and the exact error message received.

Request Assistance in Microsoft Support Forums

Security Reminder: Never post your passwords, tenant IDs, or OAuth access tokens in public forums.

Solution 2

Verify Permissions and Re-establish the Connection

Sometimes, clearing the existing broken connection and re-authenticating can resolve temporary OAuth token failures.

Frequently Asked Questions

Why does the 'Create and authorize OAuth connection failed' error occur?

This error usually happens when there is a mismatch in account permissions, an expired authentication token, conditional access policies blocking the connection, or a temporary outage in the Microsoft connector service.

Can I fix this Power Automate error by changing my password?

Changing your password might force an authentication token refresh, which could resolve the issue if the previous token was invalid. However, you will still need to navigate to the Connections page in Power Automate to re-establish and authorize the link.

Does WPS Office integrate natively with Power Automate?

WPS Office focuses on powerful standalone document productivity and does not currently feature a native Power Automate connector. However, you can export your files to standard formats (like XLSX and DOCX) that other automation tools fully support.
