I have several Mac users in our environment. Last week, several of us started receiving the "mail could not be received at this time" error message. It also states that the login credentials are wrong and a login popup displays asking for credentials, multiple times. The login ID and password are both correct, as I can log into the OWA without issue. I have tried deleting the Exchange entries in my keychain, no joy. Anyone have any ideas what causes this and what I should try next?
Thanks,
