Outlook email download very slow over my router

[JCWalf]

Outlook email sync on apple and windows products is taking ages over my sky broadband router.  Sky 4g works fine.

Have you tried rebooting your router?

Hi Mark

thanks for responding. Yes I rebooted the router and all connected devices (bar my sky+ boxes). Also ran speed test which showed expected connection upload / download speeds. It's odd if I sync mail on a phone or tablet by 4G its quick. But takes many minutes via the sky router.
