Have a Sony Xperia Z running Android 4.2.2. Added outlook.com email address successfully within native app (exchange active sync) - connects fine on initial attempt but then subsequent sync's all result in "Connection error (my email address)

Have removed and re-added numerous times with results being identical. Outlook App works fine but need to sync more than 30 days of email.

Any recommendations?

Thanks
