If you have ever torn your hair out trying to get multiple busy people to agree on a single meeting time or
have spent more time firing emails back and forth than the meeting itself then this might be the thing for you. Microsoft Garage have released a handy free tool for Office 365 and Outlook called FindTime.
This nifty add-in creates a simple poll of acceptable times that you select and sends this to all parties. They can then vote on preferred possible time slots allowing everyone to reach a consensus as to the meeting schedule. This works for people Both inside and outside of your organisation and greatly simplifies the process!
