exchange email not working

I had my work exchange account set up through mail and also through Outlook for mac, for some reason it is not recognizing my password anymore, even though I have had it reset and can access through the web access just fine. I deleted the accounts, both in mail and in Outlook, cleaned out the Keychain saves, then tried again, no luck. it was working fine until about a week ago, any ideas? Software has been updated completely as well, both Maverick and Outlook....
