User permissions in whole Sharepoint tree

Question

Hello,

I am new to Sharepoint and was wondering if there is a way to know a certain user's permissions in the whole Sharepoint tree.

For instance, to know that "user1" is a contributor in Site1, a reader in Site2, and so forth.

Many thanks in advance,

Hi @Luis Olias ,

To check user’s permission in a site, please click the settings button in the upper right corner of the webpage->Site permissions->Advanced permissions settings:

You will redirect to this page:

Click “Check Permissions” in the ribbon:

Enter username in the text box:

For Example, If I want to check a user whose user name is “Allen Xu”, enter “Allen Xu” in the box and then click “Check Now”:

Now you can check the permission level given to the user:

=====Updated=====
There are not out-of-box methods in SharePoint Online to check user permission a whole SharePoint Online Site Collection.

As a workaround, you can use PowerShell cmdlets to list a certain user’s permission in a whole SharePoint site collection and export them into a CSV file.

I attached the PowerShell cmdlets in the attachment, you can have a try.29377-ps.txt

There are a few points you need to pay attention to:
1.In this Section:

Replace $SiteURL with your own site’s URL;
Replace $UserAccount with your own site collection admin account;
Replace $ReportFile with the CSV file location you created in advance;

2.It will pop up prompt box when you are running the script:

Type in the site collection administrator’s name and password.

3.The report will be saved in the location you pointed in $ReportFile, open it and now you can see the all permissions the certain user has:

If you are still confused about this, please feel free to let me know.

Hello @Allen Xu_MSFT ,

I really appreciate the time you took for those screenshots.

My question was aimed for the whole site, meaning:

What permissions has "user1" in Site1, Site2, Site3 ?

Sort of a whole report for any given user.

Anyway, I am really thankful for your help.
