Spell Check
Here’s what you need to do to get Outlook's spell checker to kick in for every single mail that you send out.
Select Tools > Options and switch to the Spelling tab. Here, under Settings, tick the check box next to “Always check spelling before sending” and then click on OK.
Now the next time you your type out a mail and hit the Send button, the spell checker will point out any and every typo you have made.

Address Book Addendum
Double-click on an e-mail you have received from someone to open it. Right click on the sender's mail address (the From field). Next, select Add to Address Book.
To edit the person’s name you have just added, choose File > Address Book. Now select the name and click on File > Properties. Edit the name as per requirements and click on OK.

Bunching Fowards
If you want to forward several e-mail messages at the same time to someone, go to the folder containing the messages you'd wish to forward. Holding the Ctrl key down, click on each message you want to forward. Then, right-click on any message in your selection and pick Forward. A New Message window will appear with the messages attached (across the bottom of the window). Now simply complete your message and zap it off.
