SharePoint Online: How to Make a Site Collection Read Only using Site Policy?

Requirement: SharePoint Online Make Site Collection Read only.

How to make a SharePoint Online Site Read Only?
We have a business requirement to set a SharePoint online site collection into read-only mode, in order to prevent any further addition/modification of content but make the existing content available as read-only to the end-users. Unlike SharePoint On-premises, there is no UI to make a SharePoint Online site or site collection read-only. However, we can use site policies in SharePoint Online to make site collection read only.
You can set the SharePoint Online site collection to Read only using PowerShell, Refer my another post: How to Set SharePoint Online Site Collection to Read-only using PowerShell?

SharePoint Online: Make a Site Collection read only using  site policies
Here is how to use SharePoint site policies for SharePoint Online to make site collection read only:
  • Navigate to the site collection that you want to make Read Only >> Click on Settings Gear and then Site Settings Menu item.
  • Click on "Site Policies" under Site Collection Administration. 
  • Create a new policy by clicking "Create" link
  • Provide a Name to your Policy, say for e.g. "Read only", optionally the Description. Set the following options and click on "OK" to create site policy:
    • Do not close or delete site automatically
    • Check the option "The site collection will be read only when it is closed"

This will create a Read only policy. So now, We have defined the site policy which will not close or delete the site automatically but will set the site to read-only mode when it is closed.
If you don't see the "Site Policies" link under "Site Collection Administration" group of the site settings page, Head-on to Site collection Features >> Activate "Site Policy"!

Apply the policy and close the site:
Now the next step is to apply the policy and close the site.
  • Go to Site Settings >> Click on Site Closure & Deletion under Site Administration
  • Select the Site Policy you created in the previous step and click on Close this site now. (At times, You may have to select the policy and Click OK and then visit the "Site Closure & Deletion" page again to click "Close this site now" button)

  1. I am not able to unlock the site as I am not the primary site collection administrator. The Primary admin has left the company. Although I am a site collection administrator I cannot unlock the site. Any suggestions?
