I have a slight niggle. I found a useful video April Dunnam done on creating ics files to end which seemed to be my solution to send via e-mail. However upon further testing I have found that the end user can only open the ics attachment on a laptop and not their mobile device. Does anyone know how make this work for mobile users?
The ics file is being saved in a SP library if I download the ics file and send it manually the user can open the ics file on their mobile device and add it to their calendar but not via the process in the video?
