In Office 2013 the default location of Quick Access Toolbar and Ribbon customizations is still saved in to AppDatalocal folder by default and because of these settings do not roam.
In order for Quick Access Toolbar and Ribbon customizations to follow the roaming profile we can set a GPO.
User ConfigurationAdministrative TemplatesMicrosoft Office 2013Global OptionsCustomizeAllow roaming of all user customizations
Setting this will for example create officeUI files in the AppDataRoamingMicrosoft instead of AppDataLocalMicrosoftOffice.
When deploying Office 2013 you can, as an alternative to the GPO, set this in the Microsoft Office Customization Tool.
