Hi All,

Greetings for the day 🙂 LIFE IS BEAUTIFUL 🙂

Background :

Recently we got a requirement that SharePoint admin user shouldn’t access SharePoint sites / Microsoft 365 Apps via browser

This is because we have migration team and wants to allow them only to execute PowerShell CMDLETS and nothing to access site / Microsoft 365 Apps through browser or admin center

Even this is new for me so bit research and as usual SHARING IS CARING 🙂

Following are the detailed steps :

M365 - SharePoint admin center
fig : M365 – SharePoint admin center >> Policies >> Access control
  • We will be redirected to Access Control page
  • From Access control page select the option – Unmanaged devices
M365 - SharePoint admin center >> Policies >> Access control >> Unmanaged devices

  • On selection of Unmanaged devices option, right pane will be open as
SharePoint admin center >> Policies >> Access control >> Unmanaged devices >> Block access

  • From right pane, select “Block access” and click on “Save” button. – This action will
    1. Block all the SharePoint site access to all users from browser
    2. Important point New policy will be created in Azure admin center (https://portal.azure.com/) under Security >> Conditional Access with name – [SharePoint admin center]Use app-enforced Restrictions for browser access – 2021/11/19
    3. Please note the naming convention for the policy created in Azure Admin Center
Azure Active Directory admin center >> Azure Active Directory >> Security >> Conditional Access

  • To block for specific users we need to edit this policy from Azure admin center – https://portal.azure.com/#blade/Microsoft_AAD_IAM/ActiveDirectoryMenuBlade/Overview
  • Click on policy to edit and from “Assignments” section, under “Users or workload identities” click on “Specific users included
  • From right side options from drop-down – “What does this policy apply to?” select “Users and groups” option
  • Under “Include” section select – “Select users and groups” >> “Users and groups” >> “Select” option

  • From right pane – “Select”, search the user or group for which we need to block the SharePoint sites and click on bottom button – Select
  • When respective users try to access the SharePoint site (even though any SharePoint Admin), “Access Denied” error will come as
Access denied error for the users to whom “Block Access” policy is created
