content: I added Outlook 2007 to the Office 2007 I installed which didn't come with Outlook. I had been using Office 2003 with Outlook 2003 on an XP system and it had worked fine.Outlook 2007 is incredibly slow to start downloading emails and slow for each email. It may take it 5 minutes to download a couple dozen emails-no attachments or anything. These will download with Mozilla Thunderbird in maybe 20 seconds. And during that time it basically locks up everything else you want to do until it is finished. I've tried turning off everything that has been suggested that may be slowing it down but no success.I'm now using Thunderbird for my emails. Outlook 2007 was so slow the frustration level just got too high.I don't recommend buying this. Outlook 2003 was just fine but Outlook 2007 is a disaster on my machine.
