We have just made a fresh install of a Zimbra multi-server environment in our test lab consisting of three servers. All servers are running:
OS = Ubuntu Server Edition 8.04.2 64-bit
ZCS = Network Edition v5.0.13
All setting are at their default.
Our problem is with Outlook and Outlook Express. They keep giving us the following errors when trying to access the mailbox:
This is the error message we're getting:
Apple Mail works without a hitch.
An unknown error has occured.
Account: (server's ip address)
Server: (server's ip address)
User name: (username)
What are we doing wrong?
Thanks in advance.
