Safari not able to open outlook and live sites SERVICE WORKER CONTEXT CLOSED error code

If you get this error trying to open up an Outlook account or Live account when using Safari, try this...I found it on another site and it worked for me:

Anyway just managed to fix mine by going to Safari tab - preferences - privacy - manage website data, and typed in "outlook" and removed anything that came up relating to that, then typed in "live" and removed again for that - the outlook website immediately loaded after I'd done that and is now working perfectly, so just thought I would share in case it helped anyone else.
