Hello!
I'm sorry to say, to answer this is not easy…
When 1st time to run OutlookExpress, it could not convince me to use it. On the other hand, Outlook itself is more then only a mail client.
›Infected‹ by Netscape (4.x) as a browser which contains a mail client, I kept using it (now SeaMonkey). So for a lot of information I lot about OE and OL, seeing this progs working more or less good, I can not recommend this software… In fact, too, backing up the mails a.s.o.
For this, ThunderBird as a single mail client which allows (useful) AddOns would be more comfortable, would offer more usabiltiy.
