Hi all, had the HTC ONE M8 for just over a month now and loving it! I just have a quick question about the default email app. I use my o2 account on my email app on the phone but the emails disappear after a couple of days, is there any way I can keep them on the phone until I decide to delete them as some mails I have to keep for a few months ? many thanks in advance

 

that option is not in the settings

 

Yes I see that ,do I check the "all" option ?

 

I realize that but I need to keep a few many thanks
