If you are going to be out of the office, and unable to respond to e-mail messages, you may want to turn on the “Out of Office Assistant”. This will allow you to create a detailed message that will be automatically sent to anyone who sends you an e-mail message while you are out of the office. In Outlook 2007 you can set a specific date range to turn the automatic reply on/off.
In Outlook 2010 a new feature has been added. You can now create a meeting from an e-mail message.
In previous version of Microsoft Outlook you could edit an attachment, and when you closed the document and saved changes, the newly edited file would remain attached to the existing e-mail message. This process has been changed in Outlook 2010. It requires that you save the file to your computer and re-attach the file to the existing e-mail message.
When you create an “Out of Office Reply” in Outlook (Exchange Server), Outlook ONLY sends one notification to each sender that you receive a message from during the time the reply is turned on. If you would like a notification sent EVERY time you receive an e-mail (regardless of the sender), you must create a “Rule”.
If you use Exchange you have at least two address books, the “Global Address List” and a “Contacts” list. You can also create more than one address book in Outlook. You can change what address book Outlook accesses by default.
