I receive this error when trying to sign in via my student account on Office 2011 on my Mac. The install of Office 2011 worked fine, but signing in does not. I'm running OS X 10.7.5

Sorry, there was a problem while trying to connect to your account. (Error code:0x80048103)

I've googled and tried the following things, to no avail:

- changing my location from UK to US in system settings

- the same via a VPN

- removing and reinstalling

I've also read something about making sure 2-step verification is disabled on one's Outlook account, but as I'm signing in (or trying to) via a college email address I can't do that. I can see from my Office 365 account that 0 installs have been used.
