Open Outlook on your Mac and scroll down to your folders under the “On My Computer” and right click on the folder you would like to move and select “Copy Folder” as shown here:
Once you have selected “Copy Folder” there will be a menu that pops up in which you can type the name of the destination where you want to copy the folder to. Type in “inbox” and select the inbox that includes your CSU email address and then click on the “Copy” button. Example below:

The folder will also stay under your “On My Computer” on Outlook for Mac and you can keep that folder as an extra backup if you would like.
