Question details

The user encounters error 41101 when attempting to sign in to the Microsoft 365 Developer Program or related services to access SharePoint.

Product
Microsoft 365 Developer Program
Device & OS
not provided
Scenario
Attempting to access SharePoint using a Power Platform Developer account.
Observed behavior
The system displays sign-in error 41101 instead of granting access to the Microsoft 365 Developer tenant.
Before you start

Ensure you have the exact login credentials for your developer tenant (which typically end in .onmicrosoft.com and may differ from your standard Microsoft account) before proceeding.

Solution 1Recommended

Verify Microsoft 365 E5 License and Apps

Check the Microsoft 365 admin center to ensure your account has the correct E5 developer subscription and SharePoint license assigned.

Often, users who sign up for the Power Apps Developer plan assume it includes full Microsoft 365 access. However, SharePoint requires a dedicated Microsoft 365 E5 developer subscription.

1
Log in to Admin Center

Navigate to the Microsoft 365 admin center and log in using your developer tenant administrator credentials.

2
Access Active Users

In the left-hand navigation menu, expand 'Users' and click on 'Active users'.

3
Select the Account

Find and click on the specific developer account experiencing the error to open the user properties panel.

4
Check Licenses

Go to the 'Licenses and apps' tab and verify that both the Microsoft 365 E5 developer subscription and the SharePoint license are checked and enabled.

Power Apps Plan Limitation: The Power Apps Developer plan alone does not provide the full Microsoft 365 developer tenant. You must explicitly join the Microsoft 365 Developer Program to get the E5 license.

Frequently Asked Questions

Why do I get error 41101 when accessing SharePoint on a developer account?

This error typically occurs if your account only has a Power Apps Developer plan instead of a full Microsoft 365 E5 developer subscription. A dedicated E5 subscription is required to access SharePoint services.

Do I need separate accounts for Power Platform and Microsoft 365 developer programs?

Yes, in many cases, the signup account used for the Power Platform and the administrator account created for the Microsoft 365 developer tenant are different. Ensure you are logging in with the correct .onmicrosoft.com admin credentials.

What should I do if my region is not supported for a Microsoft 365 developer account?

If your region is currently unsupported or experiencing capacity constraints, you may need to wait for Microsoft to expand availability or contact Microsoft support directly via the admin center for an alternative solution.
