I'm new to iPad and ios7, so bear with me. Recently acquired an iPad Air. I set up two mail accounts - Gmail and Hotmail and both appear to be working OK. However, when I set up the Hotmail account I got a "Mail Days to Sync" prompt. When I set up the Gmail account this prompt didn't appear - Why ?? I'll admit I don't fully understand "Mail Days to Sync". I've read various threads about this and the more I read the more confused I get ! Is there a basic difference in the way Gmail and Hotmail work on an iPad ? I thought all web based email accounts just access the appropriate e-mail server and display on your device, (iPad or PC), all the mail messages in your account or are the e-mails actually stored on the iPad ?? On the Hotmail account I had Mail Days to Sync set to 1 day - I then changed it to "no limit" and the Mail icon on the home screen displayed a value of 312 in red. I changed it back to 1 day and it reduced to just 5. What does this mean ? A number of questions in this post, - explanations in simple terms please.!!
