With all due respect to Dreamboat, I have been using Outlook since it came out as part of Office 97. I am not a computer professional.
I find Outlook to be easy as pie. As I replied, I use it to direct correspondence to vendors: purchase orders, tax exempt certificates, inquiries, you name it, I send it.
Of the two problems that I originally had with Outlook 97, one has been fixed. That problem was that Outlook would not correctly parse email addresses and fax phone numbers when one imported a database from Access or any other existing application. You would not get a "Fax Phone Book" to use with Microsoft Fax (which still existed in Win95). I bludgeoned Microsoft into having the guy call me who had written the VB script fix for that problem. For onyone who needs it, it is in Q166333 in the Microsoft Knowledge Base.
The last and still problem is that you can not import Keywords into a field called Keywords, even though you can map to that field. It is just not there. So, if you have search keys, or Key words, you need to pick some other text field, one for which you have no other use.
Beyond that, I love Outlook.
