A collaborative workspace app in Microsoft 365 designed to help teams co-create, stay organized, and work together in real time across apps and devices.
Welcome to Microsoft Q&A forum.
What you’re seeing is usually a mix of account and feature limitations in Loop for personal or Family subscriptions, plus the way Loop handles invitations, it can say “sent” but the recipient may not receive an email and nothing visibly changes on your side.
Here are some suggestions you can try:
Have the recipient check Loop directly (not just email).
With personal Microsoft accounts, invitations may not arrive as an email, but the workspace can still appear inside the recipient’s Loop home screen once they sign in with that same address.
Make sure you’re inviting an address that can actually sign in to Loop as a Microsoft account.
Loop workspace invites are designed around a sign-in identity, if the person is using a non-Microsoft email (or they are signed into Loop with a different account), the invite can effectively “go nowhere” from the user point of view.
Use “share a page” as a workaround when workspace membership won’t stick.
Page and component sharing grants access even when workspace-level adding is unreliable, and it often bypasses the “member count never changes” symptom because it does not rely on workspace membership being created first.
Try a clean browser session (private window) and re-authenticate.
Loop sharing depends heavily on session tokens, so signing out, then signing back in and retrying in a private window can clear a stuck invite flow that looks like it sends but then silently drops the entry.
If you need dependable workspace member management, use a work or school (Entra ID) account and the right plan.
Microsoft’s own licensing guidance indicates that adding and removing workspace members is tied to specific business or education plans for work accounts, and personal experiences can be more limited or inconsistent.
Hope this helps. Feel free to get back if you need further assistance.
