I keep getting errors like this:

Outlook cannot find the server. Verify the server information is entered correctly in the Account Settings, and that your DNS settings in the Network pane of System Preferences are correct. Error code: -3176

I have the latest Outlook 2011, latest Yosemite Macos, and 4 different accounts of which one is Office365 Exchange and the others are IMAP, including Outlook.com, gmail, iCloud and a private IMAP server.  All of them give me this error from time to time. The bizarre part is that once I clear the message, all of the accounts send and receive mail just fine. Its not like Outlook is not actually able to connect to my accounts; its just that if gives me a series of apparently bogus error messages that I have to constantly clear, including ones that take screen focus away from what I'm doing.

Has anyone seen this, and does anyone have any idea of what to do about it? I'll point out that this problem persists across multiple installs of Outlook on a couple of Macs and Macos versions, so I'm certain its not my Outlook settings. Clearing and reinstalling Outlook does not fix the problem in any way.

Thanks!
