Outlook 2013 gives you the option of using commas as address separators for emailing purposes if you need to do so. If you plan to email your class through myHill, configuring the comma separators is key for ensuring the functionality of this tool.
1. From your Inbox in Outlook 2010, go to File, and then Options.
2. Once in Options, select Mail from the left-hand column. This will change the options shown in the right-hand view of the window.
3. Scroll down the settings until you reach the heading "Send messages."
4. Under the "Send messages" heading, click the check box next to "Commas can be used to separate multiple message recipients," and then click the OK button.
