If you use Office 365, you are probably aware about the Microsoft Forms feature which allows you to create quiz or surveys.
Well, until now when you wanted to collect responses you had to either copy the link and manually share it, send an email, use a QR code or embedded the link on a web page.
You can now send an invitation – which is a little bit different than the ‘send an email’ option because it does not start a new email using your mail client.
You can then directly fill up the list of recipient as well as update the text directly in the web page (similar to the sharing option on SharePoint)
