Offline Files error - 0x80070718 Not enough quota is available to process this command

I was copying files from an old PC to a Win7 64 bit laptop for a client with an SBS2011 server. The laptop was at home, offline, when it started warning about not being able to copy any more files - to be fair there were 20GB of photos involved.

Those laptops are setup to use Offline Files, so the Documents folder is available away from the office. Sounds an easy one, the SBS2011 server has a 2GB file quota for users by default. I checked it was turned off ok, then connected via VPN, tried another copy, still no luck. Double-checked that setting, turned it on and off, again no luck. Had to be something else - not as obvious unfortunately.

Tracked it down to a local limit on the laptop - the offline files disk usage limit was too low. Look in Control Panel > Sync Center > Offline Files > Manage Offline Files > Disk Usage > Change Limits

A more useful error message would have saved a bit of time there.
