1. calendar returns messaging interface has returned unknown error
My outlook mail has worked fine for year. I am trying to use Calendar for first time. However, I can't enter any events ... whenever I try, I always get dialogue box that reads, "The messaging Interface has returned an unknown error. If problem persists, restart Outlook." Restarting outlook does not resolve the problem. I operate three profiles on my outlook with different e.mail addresses. This problem occurs on all three. I've tried mail, contacts, notes, tasks, and journal wihtin Outlook and they all operate just fine. What do I do next? Your help is appreciated ~ thanks much!

3. fix error message-messaging interface has returned unknown error
I have received this message while viewing shared calendars. I have rights when I first start calendar and can view and edit shared calendars. About an hour or so later, I received this error message and can not view shared calendars. I have shut down Outlook and reopen and can view the shared calendars but in an hour, the problem happens again. It's annoying to do this multiple times a day.
