Organizing and accessing contact information in Outlook.com
Hi,
Welcome to the Microsoft community. It seems that you encounter a problem setting-up Outlook.com using Exchange Activesync on my Symbian belle (Nokia 808) but doesn't happen with your office e-mail.
Please check the link on Ken_Rey_C.'s post in this thread for the correct server name.
I've moved the information to the private message.
Let us know if you need further assistance.
Thanks!
