View in File Explorer option missing in SharePoint Online Edge browser

Microsoft 365 apps and services no longer support Internet Explorer. So now you cannot open your SharePoint document library files in explorer view.
The "View in File Explorer" menu option is not visible by default on modern SharePoint document library interface in the Edge browser. But there is a way to enable it for libraries 😀.

⚠️ IMPORTANT: Microsoft no longer recommends use of View in File Explorer and encourage using the OneDrive sync client.

⚡️ Microsoft Edge Stable version 93+ is supported and users can enable the View in File Explorer capability on SharePoint for modern document libraries.

Follow below steps -

✔️ Enable "View in File Explorer option" at the SharePoint Online tenant level

Run below commands using PowerShell (Run as Administrator), take help form your Tenant Admin

#Connect to SharePoint Online Admin Center
Connect-SPOService -Url "https://code2care-admin.sharepoint.com"
 
#Enable View in File Explorer option for SharePoint Online
Set-SPOTenant -ViewInFileExplorerEnabled $true

#Enable Persistent Cookies to operate correctly
Set-SPOTenant -UsePersistentCookiesForExplorerView $true

✔️ Enable Edge policy "ConfigureViewInFileExplorer" to open WebDAV URLs in Windows File Explorer.
This policy should be pushed as a GPO to configure for all users.

1. Navigate to [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge], create a new key "Edge" if it does not exist
2. Create new String Value "ConfigureViewInFileExplorer"
3. Set value as it as "[{"cookies": ["rtFa", "FedAuth"], "domain": "code2care.sharepoint.com"}]"

You may require to run GPUpdate.exe /force from Command Prompt to refresh the settings

Restart Edge now and access the library, explorer should should be back under the View section menu (Library > View Menu > View In File Explorer). It may take up to 15 minutes for the button to appear.

⛏️ Troubleshooting errors

• The requested operation is part of an experimental feature that is not supported in the current environment - it is less likely, but will happen if the feature is not rolled out for your tenant.
• This policy is blocked - its value will be ignored appeared while checking to see if the policy was applied via edge://policy - can happen when you attempt to apply this policy to a non-domain joined device. ConfigureViewInFileExplorer policy can only be applied to devices joined to a Microsoft Active Directory domain, Windows 10 Pro, or Enterprise instances enrolled for device management.
• View in File Explorer button not appearing in SharePoint - tenant setting is not enabled.
• Blank screen when clicking View in File Explorer button - Edge policy is not enabled
• ViewInFileExplorerEnabled option not be available in PowerShell - Management Shell version should be 16.0.21610.12000 or higher.

⭐ You can also Map SharePoint Online library as network drive.

The Tenant Admin can also enable the explore option using Intune.
