Sorry, can't seem to find answer to this when searching the forums...

I need an email client (other than Novell's Groupwise) that will work with a Groupwise server on OS X (Yosemite)

I think I read that the Apple Mail client is no-go... but is Outlook 2011 also not possible?

I tried connecting to our server via IMAP, by plugging in the credentials to the mobile mail server (I am able to connect via iOS mail)

But no go, get error -3260.

Curious what other people are doing in this boat. (I'd really prefer not using the webmail method)
