Update the colors that are assigned to categories in the MCL in Outlook 2016 for Mac. Random colors are assigned to these categories because the colors from Outlook for Mac 2011 aren't synchronized. So when you migrate from Outlook for Mac 2011 to Outlook 2016 for Mac, any local category names that are assigned to items are merged with the MCL. Outlook 2016 for Mac uses the Master Category List (MCL) that's stored on the Exchange server to synchronize the category names and colors. However, the colors for these categories aren't synchronized to Exchange. This makes the names visible on different clients and devices. The names of these categories are synchronized to the server that's running Microsoft Exchange Server when they're assigned to items. Outlook for Mac 2011 uses a local list of categories.
