We know that a number of staff have been working with Office Mix – however, it is being discontinued. If you have any presentations that were developed using mix, please see Microsoft’s information about migrating your presentations. (You may find that you have to sign in several times to complete the migration process)
Microsoft have updated the latest versions of Powerpoint (Windows) and the online version (sign in, with UoD credentials, required) to allow the addition of quizzes etc. For more information, please see Microsoft’s help.
