Hi, We are currently using Mdaemon 10 and I am testing zimbra open source 8.0.2 on ubuntu 12.0.4 LTS on 64 bit. I installed zimbra mail server and able to create users through admin UI. I created users and logged through browser into their account. But when i tried to configure same account in outlook 2010, i am getting authentication error and it keeps prompting for password.

Any light of help is highly appreciated.

Thanks in advance.
