Does one need to have Outlook installed for this to work? I tried clicking it and the appointment opened in a text file as I use Mozilla Thunderbird, not Outlook. I didn't get credit, but wasn't sure if it was because I don't have Outlook installed, thus the appointment couldn't save properly, or that maybe they reached a daily max.
If anyone got this to credit and does not use Outlook, I'd be interested to hear. I plan to give this a go again tomorrow earlier in the day in case it just reached some daily max.
