@lisha92: I'm not sure what could be causing this issue. If you're using the Samsung Email app, please try opening the app > Tap the 3 lines in the top left > Tap the cog in the top right of the pop-up window > Selecting your account > Sync account > On. Now, swipe from the top of the screen to the bottom, then again to enlarge the Quick Panel, and make sure that 'Sync' is toggled on here. You may also wish to try deleting some messages from your inbox, just in case you have reached your maximum storage capacity. Alternatively, reduce the timeframe of your Sync period, so only your most recent emails are pushed through to the app.
