Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear Jessica,
If you copy and paste the link from the place in the provided screenshot to the browser, the link will become the item display form link which looks like **https://contoso-my.sharepoint.com/personal/username\_contoso\_onmicrosoft\_com/Lists/listname/DispForm.aspx?ID=itemid** and it isn't an anonymous link. The anonymous link should be in the following format. https://contoso-my.sharepoint.com/:li:/g/personal/username\_contoso\_onmicrosoft\_com/dynamic guid
I suggest you check whether the link format is correct in your environment.
You may need to copy and paste the link from the original place in the provided screenshot again and back up it.
Please confirm whether you copy and send the link from the browser in your environment.
Welcome to share any updates at your convenience if you need further help.
Sincerely
Cliff | Microsoft Community Moderator
