Not able to open One drive folder

Hi Savannah,

Based on the symptoms you've described, there is a chance is that your account was recreated when you rejoined the organization, resulting in a mismatch between your current account identity and historical sharing permissions.

Although you are using the same email address as before, OneDrive and SharePoint permissions are assigned to an internal user identity rather than the email address itself. If your original account was removed and a new account was created when you returned, some users' OneDrive sites may still contain permission entries that reference your previous account identity.

Please reach out to your IT admin and ask them to verify this issue. The resolution must be carried out on each individual OneDrive account of those unable to share with the affected user.

A Global Admin or SharePoint admin can carry these tasks out, or it can be delegated to the sharing user. If performing this task as an admin, you must first add yourself as a site collection owner on the account of the sharing user.

To do this, go to the SharePoint admin center, click on More features, then Open the User profiles section. Search for the sharing user and in the results section, click on the drop-down arrow beside their Account name. Select Manage site collection owners and in the window that appears, add your own account under Site Collection Administrators. This will allow your IT admin access to your OneDrive and the ability to remove the old account from the user permissions.

1. Navigate to the SHARING user's OneDrive All People permission list by pasting /_layouts/15/people.aspx?MembershipGroupId=0 at the end of the user's main OneDrive URL (https://mainsite-my.sharepoint.com/personal/user_email_address_com -- the format of the user's email may not match what I've written; that's the format of my company's email addresses.)
2. Locate the affected user in the list and hover over their name and a URL will appear in the status bar area. Note the ID=#### at the end. Do not click on the user, only hover to reveal the ID.
   
3. Go to the userdisp.aspx page by pasting /_layouts/userdisp.aspx?id=10&force=true onto the user's OneDrive URL and replacing the 10 with the number of the ID from the previous step. For this example screenshot the ID is 266 so you would paste /_layouts/userdisp.aspx?id=266&force=true onto the OneDrive URL.
4. You will be taken to a People and Groups > User information page with the affected user's information listed. Confirm it is the affected user, then click Delete User from Site Collection. Confirm the deletion.
5. Upon deletion, you will be returned to the People and Groups > All People list from step 1.
6. All files must be re-shared with the affected user.

I hope this provides enough clarity and helps you stay inform with your current situation.

Hi Savannah,

In order to assist you with more accuracy, can you please provide with additional information:

• Are you signing in with the same work account/email address that originally had access to the folder before you left the organization?

What exact error message do you receive when you try to open the folder? (A screenshot is helpful if available.)

Can you access other shared OneDrive folders and Microsoft 365 resources, or is the issue only with this specific folder?

Has the folder owner re-shared the folder with your account since you rejoined the organization?

When you rejoined, was your account reactivated or recreated as a new account by IT?

• Are you trying to access the folder from OneDrive on the web, File Explorer (sync client), Teams, or SharePoint, and does the issue occur in all locations?

To ensure I provide the most accurate assistance, I would appreciate any additional information you can share regarding your current situation. If possible, please include screenshots, as they can be very helpful in the investigation.

Thank you for your patience and understanding. Should you have any further questions, please feel free to contact me at any time.

I look forward to your response.
