Whenever an email sits in my inbox for a long time (I would estimate around a week) it suddenly just disappears from my iPhone Mail app. (I use Outlook 365 for University and Gmail for home and they both do it).

The email will still be on the Mail app on my MacBook but the iPhone and iPad don't show it - seriously this is annoying - what gives?
 
Change your number of mail days to sync. Settings --> Mail, contacts, and calendar. Click the account name.
