Unable to @ mention external collaborators in comments within Office online files
Is anyone aware of whether Microsoft will someday enable the ability to @ mention users who do not belong to the M365 tenant within comments in Office online files? I've attached a screenshot of what this looks like in a Word Online file in OneDrive.
There are a number of Microsoft feedback posts about this, but it really feels like an unnecessary gap in functionality.
Anyone have any insights on roadmap?

In Microsoft 365 / Office Online, you can’t @mention external users in comments.
@mentions trigger identity + notification workflows tied to your tenant. It only works for users inside your tenant.
Workaround: share the file and notify them separately (email/Teams).
No confirmed roadmap yet from Microsoft.
