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.
After creating quick parts (see online tutorials for instructional video), you can quickly access or preview the “Quick Parts” you have created. This works the same in Word 2007, Word 2010, Outlook 2007, and Outlook 2010.
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.
There are times you may need to know if a cell is part of a formula. If you are altering or deleting cells, you can easily cause errors throughout your worksheet. Using "Formula Auditing" you can easily determine if a cell is part of a formula. The technical terms for this are "Trace Dependants" and "Trace Precedents".
