Microsoft: “You can also select to allow or prevent commenting on modern pages. If you allow commenting, it can be turned on or off at the page level“
By default both
– Allow users to create new modern pages
– Allow commenting on modern pages
are turned on (enabled)
Tenant or SharePoint admin can find settings under
SharePoint Admin Center -> Settings -> Pages
When you are creating a modern site page – there is an option “Comments” turned On by default:
And page with comments looks like:
Comments on site pages (aka modern pages) can be enabled or disabled at each of the levels:
– Tenant level
– Site (aka site collection) level
– Web (aka subsite ) level
– Page level
Here is how it is done:
|Level||How it’s done||Who can do it|
|Tenant||GUI ( SharePoint Administration)|
|Global Administrator or |
|Site (Site Collection)||PowerShell||Global Administrator or|
|Web (Subsite)||PowerShell||Site Collection Administrator or Owner|
(Full Control rights to web)
|Page||GUI (Page Editing screen)||Site Member |
(Edit right to page)
If commenting on modern pages disabled at higher level – lower level settings do not work. E.g. If you disable “Allow commenting on modern pages” at tenant level (it takes minutes) – the functionality will gone from all modern pages of all sites.
When you switch page comments Off – all existing comments will be hidden (but not deleted).
If you later turn comments On – comments will reappear, including Likes.
If “Allow commenting on modern pages” disabled at tenant or web level – you will not see “Comments On/Off” switch while editing page.
If “Allow commenting on modern pages” disabled at site collection level – you will see “Comments On/Off” switch while editing page, but you will not be able to turn it ON.
When you disable “Allow commenting on modern pages” at tenant level –
PowerShell Object (site/web) property “CommentsOnSitePagesDisabled” will not be changed for any site/web.
You can still with PowerShell set it to True/False:
but it does not take any effect.
If you enable “Allow commenting on modern pages” at tenant level (it takes ~10 minutes) – the functionality will return to all modern pages and
all webs and sites properties “CommentsOnSitePagesDisabled” will ???.
You can change it with PowerShell:
# having Site Collection Admin Permissions: # disable Comments On Site Pages for a subsite: $webName = "SubSite_02" Set-PnPWeb -Web $webName -CommentsOnSitePagesDisabled:$true # enable Comments On Site Pages for a subsite # (only if comments enabled at tenant level): Set-PnPWeb -Web $webName -CommentsOnSitePagesDisabled:$false # having global admin or SharePoint admin permissions: # site collection: Set-PnPTenantSite -Url $siteUrl -CommentsOnSitePagesDisabled:$true # tenant-level Comments: Set-PnPTenant -CommentsOnSitePagesDisabled:$true # disable comments Set-PnPTenant -CommentsOnSitePagesDisabled:$false # enable comments # does not work: Set-PnPSite -CommentsOnSitePagesDisabled:$true
– Microsoft “Allow users to create and comment modern pages“
– Allow users to create modern pages
We did not discuss “Wiki Pages” or “Web part Pages”, we discussed only “Modern Pages” (aka Site Pages).
I have tested it all personally using Communication sites.
MS-Team (group-based) and standalone SharePoint (no-group) sites – TBP.
