Been using the mail app without any problems to connect to my work email using the following exchange address: webmail.[companyname].com, for the longest time.

Recently was having connection problems so decided to delete the account and restart.

This time when I try to set things up I get the following error: "Setup could not finish. Unable to connect to server".

Can I assume that my work has changed something, so I can't use the webmail server to connect to exchange?
