SharePoint Online Open in Explorer with Microsoft Edge11 Sep 2021 | SharePoint Online
With the next release of the SharePoint Online cmdlets, Microsoft will support allowing Microsoft Edge to open Document Libraries with Windows Explorer, similar to how IE has operated with SharePoint for eons (in the IT world, anyways!).
This will require two configuration points:
Update to the latest Microsoft.Online.SharePoint.PowerShell cmdlets, version 16.0.21610.12000. While they’re not yet on the PowerShell gallery as of this post, you can use the MSI download, instead. You’ll run the following PowerShell:
Connect-SPOService https://tenantName-admin.sharepoint.com Set-SPOTenant -ViewInFileExplorerEnabled:$true
The tenant setting is false, by default.
The second step is to enable a policy in Microsoft Edge, version 93 at a minimum. This will require you to configure the policy on a per-SharePoint Online domain basis. You can read more about that configuration here.
Note that this feature has not yet rolled out to all tenants, yet. Your tenant may not support this feature as of this time, in which case you’ll see the below error.
Set-SPOTenant : The requested operation is part of an experimental feature that is not supported in the current environment.
This is great news for Edge users and excellent to see so quickly after the deprecation of Internet Explorer for M365 services!
