[Q] motification from calendar topic

Hello, I have a question regarding syncing my calendar events with notifications in my email. I have tried clicking all the buttons in my settings re mail accounts and there is only sporadic notifications. Usually not! I want to sync 24 hr notices to my isp mail account rather than my Google Mail account. I can't sync to either right now. I know it is possible, because, occasionally right out of the blue I will get one......strange. If I put in test events, none come through. I have no problem with doing this with my Asus tablet. Would anyone have any suggestions? Thank you for any help. BILL
