Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
If sending the invitation by email is not working, you can use the Copy Link option instead and share the invitation through SMS, a messaging app, or social media.
Tell to try accepting the invitation in an InPrivate/Incognito window. Also, make sure that they are not currently signed in to another Microsoft account on their computer to avoid any conflicts.
- Go to https://account.microsoft.com/services
- Sign in with the Microsoft account that owns the Microsoft 365 Family subscription.
- Under your Microsoft 365 Family subscription, select Start Sharing.
- Choose Copy Link.
- Send the link to the person you want to invite using your preferred messaging or social media app.
- Ask the recipient to open the link and accept the invitation.
Please note that the invitation link is valid for 48 hours only. If it is not accepted within that time, it will expire and you will need to generate a new invitation link.
