Just installed Office 2010 Home and Business and everything is fine except Outlook. My primary e-mail address is a hotmail account (Windows Live ID) and I have several accounts with hotmail, google, and yahoo that I want to link. I have no problem adding the gmail account. I know the process for adding accounts of all styles, it just won't connect to hotmail and yahoo (even after downloading the hotmail connection whatever pack). However, the send/receive process can never finish all tasks and I receive constant errors about not being able to authenticate the Windows Live ID, not able to connect, could not synchronize accounts, etc. I do everything it promts and still things just appear to be stuck in the attempted synchronization mode. Yahoo accounts just are not connecting period. When things are stuck in this mode, it causes my computer to slow to a crawl.
