Thanks for reaching out! Based on what you’ve described, this issue doesn’t appear to be related to the unification changes. It looks like your organization may have disabled the option to create "Anyone with the link can edit" sharing links around the same time.
To manage this setting, you can use the Microsoft 365 admin center or PowerShell. Here’s how:
Option 1: Microsoft 365 Admin Center
- Go to: https://admin.microsoft.com
- Navigate to:
- Settings > Org settings
- Select SharePoint (this also applies to OneDrive)
- Under Sharing, configure the following:
- Choose the default sharing link type: You can set it to View, Edit, or None.
- Limit sharing by link type: You can disable Anyone links entirely or restrict them to view-only.
- Save changes.
Option 2: PowerShell (Advanced)
You can use PowerShell to configure link settings more granularly.
# Connect to SharePoint Online
Connect-SPOService -Url https://yourtenant-admin.sharepoint.com
# Disable creation of Anyone links
Set-SPOTenant -SharingCapability ExternalUserSharingOnly
# Or restrict to view-only links
Set-SPOTenant -DefaultSharingLinkType View
Replace https://yourtenant-admin.sharepoint.com/ with your actual tenant admin URL.
Let us know how you go.
