Attempted to perform an unauthorized operation

[Mohamedbg23]

Hi @Zerg00s,

I'm facing some issues while migrating from one site to another. During testing, I've encountered errors related to connectivity and permissions.

When trying to migrate a list from the source site, I encountered this error:

Another issue I'm having is that the login popup for the target site permission isn't opening. It appears to automatically log in with the source login information, and I'm not able to see the target login popup.

Lastly, when setting Clear Credentials to True, two login popups appear. After logging in to one of them, the other one closes automatically and I receive this error:

Any help in resolving these issues would be greatly appreciated. Thanks!

Hi @Zerg00s,

I'm facing some issues while migrating from one site to another. During testing, I've encountered errors related to connectivity and permissions.

When trying to migrate a list from the source site, I encountered this error:

Hi @Mohamedbg23. What kind of permissions do you have at the source site? Are you a site collection administrator? Are you able to test it?

Can you open these two pages and see your account there?

• https://kdf4.sharepoint.com/sites/mysite/_layouts/15/mngsiteadmin.aspx
• https://kdf4.sharepoint.com/sites/Mohamedproject/_layouts/15/mngsiteadmin.aspx

If not, can you add your account to the Site collection admins and try again?

Lastly, when setting Clear Credentials to True, two login popups appear. After logging in to one of them, the other one closes automatically and I receive this error.

It sounds like you are migrating between two sites of the same tenant. Do you want to use different accounts for both the source and the target sites?

Dear @Zerg00s,

Thank you for your quick response. I followed the links you provided and tried the suggested solution for the first issue. I added the site owner's email address manually to the site collection administrators, as shown in this screenshot:

However, the issue persists and I still can't access the site.

I also noticed that you didn't mention the second issue I posted. Can you please advise me on how to proceed?

Thank you for your help.
