These tweaks are software applications that will enable users to improve the performance of Outlook with new functions.
Since most of these apps are add-in, therefore they integrate within the program's interface. This way, the users will be able to easily track time, expenses and projects when using Outlook, or to locate and remove all the duplicate emails from all folders.
Additionally, these tweaks will also provide users with email alerts that will display a notification whenever a new message arrives.
Furthermore, add-ins can also enable users to view selected emails, calendar items, contacts or notes in external files (such as PowerPoint presentations).
