"Loading data, please wait..."
You'll generally see this when BT Mail is trying to load data from the servers and may not be getting a response.
It doesn't necessarily indicate there's a problem, but sometimes it's to do with local network connectivity. Try the following:
check your broadband's connection and speed >
restart your computer or device and power cycle your BT Home Hub >
close your browser, log out and back in
clear your cookies and cache >
if you're connecting using wireless try changing the wireless channel on the BT Home Hub >
If you've tried to fix this and you're still getting problems, please get in touch with us >
