A couple of guys from work have mentioned this, so thought I'd post here and see if anyone could post some suggestions.
2 guys, both in the Christchurch area have queried about how their phones wont sync work emails while they're at home while connected via WiFi on the supplied HG659 routers. Both individuals have recently moved to Vodafone Fibre. Current solution is to turn off WiFi on their mobiles and sync via data. Their laptops work without a problem.
Office 365 Exchange Email sync works without a hitch at work, which is also on VF Fibre, though not using a HG659 . These are VF supplied Lumia 640 devices.
Any ideas?
