Signing in to ZoHo through MS Outlook Add In

Signing in to ZoHo through MS Outlook Add In

Apols if this has been done before. I can't sign in to ZoHO through the Add In function. It tells me " please specify a valid email and password.

I have uninstalled the app twice, changed the password twice and still no good. My colleague has used my details on his lap top and signed in without a problem. I guess it must be my laptop and some conflict.

Anyone got any ideas.

Cheers

Tim
