We are running Office for Mac 2011. All up to date with MS software updates. Our email is Office 365 hosted. We have Comcast as our small business internet provider. Occasionally we get error messages in Outlook that tell us that the password for an Exchange account is not valid and do we want to re-enter it. Re-entering it does not work. These connection problems only happen at the office. No member of the company has ever experienced them outside of the office. Anybody else having this issue?

Hi,

(Still got the value to reference for you:))

But this thread seems to be related to Office for Mac and Office 365, better to post your question to the right place:
