I am an O365 but i have a client that has Google. When he receive appointments from me, his calendar ignores his default notification settings. he has his default settings set for a pop up 10 minutes prior, an email 10 minutes prior, and a SMS 30 minutes prior. However the only notification that is bound to the appointments when he open it to view the details is the pop up, which happens to be the least useful for him personally.
he uses Chrome to access his google apps account, running on Windows 7 (32 bit.)
When he create an appointment him self, there are no issues with notifications. Per the user documentation, he has tried removing and re-adding his notification methods in the calendar settings, to no avail.
Is this an O365 problem?
