Outlook Send a Message to a Category
I've shown how to use the Category feature in the past; but other than sorting, some users aren't sure how else to use this feature.
Let's say you've setup a Category for your son's sports team. When you need to send a message to the team, simply filter your Outlook Contacts by typing the Category name in the "Look For" field and press "Enter."
When the names in the Category appear, press "CTRL A" to select all of the contacts. Choose "Actions" from the menu and select the "New Message to Contact" option.
All email addresses within the Category appear in the "To" field of a new email message window.
Type your Subject Line and email message and press the "Send" button.
It's that simple!
