IE 11 breaks Outlook Web Access "full" mode (not "light" mode).
To fix this, in IE:
Go to Tools/Compatibility View Settings
Add your OWA domain (mail.widgetsrus.com) to the "compatibility view" list.
Restart IE (just to be safe).
Full OWA mode should work.
I figured this out thanks to a post on TheRegister.co.uk
Another recent tech annoyance and fix that I've come across and that I thought was worth sharing. (Also, well done, Microsoft...breaking your own product within your own product!)
