The software only allows you to sync one month worth of emails. I am hoping this is addressed in one of the software updates.
Hello Tryemall. I understand your frustration with your device not syncing as many emails as you would like. At this time you can try manually syncing your emails which should allow you sync more than one months worth of emails.
my emails just vanish after synching. still on my server not on my phone and can not pull them up
