I get this error for several items in the at the time of this post latest version Outlook 2011: 14.4.1

I have tried to create a new Office profile and setup Outlook to synchronise everything again, but the same issue occurs.

Any ideas? Can it be something on the server perhaps?

I've been trying for years to find a way to synchronise my emails from Webmail and Outlook for Mac. The problem is I have lots of email addresses that I want to be able to see in the same place.

If you know how to do this, I'd be really grateful for your advice, but I've found it to be a bit more complicated than it seems at first.

Here's a full description of what I'm looking for:

Thanks for your help in advance
