Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Dear Xiao Mi,
Good day!
Thanks for reaching out to this community.
Based on your description, I understand your query about how to fix the Power Automate error - You can't sign in here with a work or school account. Use your personal Microsoft account instead.
Please note that Microsoft accounts (such as outlook.com, hotmail.com, msn.com accounts) are for personal use, and for accessing services like Outlook.com, Xbox or Skype. And the account that you want to use it a Microsoft work and school account, which is for organizations that use Microsoft 365 for business.
For more info, What's the difference between a Microsoft account and a work or school account? - Microsoft Support
In your case, you may try to use the template "Save Office 365 email attachments to OneDrive for Business" instead.
(To use the template "Save Outlook.com email attachments to your OneDrive", you may need to create and use a new Microsoft account.)
Furthermore, since Microsoft has specific support channel capabilities for certain scopes and different support attributes and we provide some limited knowledge about some aspects of the scenarios, for questions specifically related to Power Automate, I recommend posting your concerns in the appropriate community at Microsoft Power Platform Community Forum Thread. Experts in this category have extensive knowledge of Microsoft Bookings and can provide customized solutions to unique problems.
I apologize for redirecting you to a different community, but I believe this step will ensure faster and more accurate assistance for your specific scenario.
Thanks for your understanding. Your patience and cooperation will be greatly appreciated!
