InfoPath Forms Services and External Users
A few weeks ago on Twitter we saw an interesting post regarding InfoPath forms not working properly for external users. Naturally we had to investigate this issue, because as a consulting firm it's important for us to know these little quirks and kinks before recommending an InfoPath form solution to companies that might have a lot of external users. Thanks to Twitter's 140 character limit, I didn't have a lot of information to go off of to launch my investigation, so I decided to start in the most obvious place and then dig. I opened InfoPath and created a very simple SharePoint List Form and connected it to my SharePoint playground. Then I invited my personal email address to the site as an external user and tried to interact with the InfoPath form and list. To my great surprise, it worked. I decided I needed more information on this InfoPath form issue.
