Fix Power Automate Excel Online Connection Error AADSTS65002
Question details
The user is unable to establish an Excel Online connection in a Power Automate flow after changing their email account, encountering a preauthorization consent error.
- Product
- Power Automate and Excel Online
- Device & OS
- not provided
- Scenario
- Recreating an Excel Online (Business) connection within an existing Power Automate flow following an email account update.
- Observed behavior
- The system throws error code AADSTS65002, stating that consent between a first-party application and resource must be configured through preauthorization.
Ensure you have your Microsoft 365 tenant administrator's contact information handy, as resolving Azure AD preauthorization consent errors typically requires admin-level access.
Request Support from the Microsoft Power Platform Community
Because AADSTS65002 is an Azure AD tenant and preauthorization consent issue, it requires specialized investigation by Microsoft support or action from your IT admin.
Error AADSTS65002 occurs when an application requires admin consent to access a resource (like Excel Online) but hasn't been granted it. Since this involves backend Azure Active Directory policies that often change or get triggered when user identities are modified, community experts and IT admins are best equipped to resolve it.
Copy the complete AADSTS65002 error message and make a note of the specific flow actions that are failing to connect.
Visit the official Microsoft Power Platform Community website and navigate to the Power Automate section.
Create a new support topic detailing your recent account or tenant changes, and the connector you are using. Ensure you do not expose any passwords, tenant IDs, or sensitive client secrets.
Reach out to your organization's Microsoft 365 admin, as they may need to log into the Azure portal to manually grant consent for the Excel Online connector on behalf of your new email identity.

Frequently Asked Questions
What does error AADSTS65002 mean in Power Automate?
This error indicates that the application (such as Power Automate or the Excel Online connector) is missing the necessary preauthorization or consent from your tenant administrator to access the requested resource.
Can I fix the Excel connection error AADSTS65002 without admin rights?
Generally, no. If the error requires configuring consent between a first-party application and a resource, it must be done through preauthorization in Azure Active Directory, which strictly requires admin privileges.
Why did my Excel Online connection break after changing my email?
Power Automate connections are tied to specific user identities and authentication tokens. When an email account changes, the old authentication token becomes invalid. Recreating the connection can trigger new security consent policies that were implemented since your initial setup.
How do I safely share details in the Power Platform Community?
Provide the exact error code (AADSTS65002), the steps to reproduce the issue, and the names of the connectors you are using. Never share tenant IDs, client secrets, passwords, or personal email addresses on public forums.
