Outlook and iCloud

I use iCloud with Outlook 2010 and have been very pleased with the way it operates however yesterday, after the recent major Win 10 patch, I can no longer access my calendar and contacts - I get the message that the information store cannot be opened. I have tried uninstalling iCloud and re-installing but no joy. Googling doesn't seem to provide any sensible answers. Has anyone else experienced this?
