Best practices: Using OffScrub

The Best Practices Guide includes deployment recommendations and real-world examples from the Office 365 Product Group and delivery experts from Microsoft Services. For a list of all the articles, see Best practices.

The Office Scrub tool (OffScrub) is the best way to remove a previous version of Office. OffScrub has a better success rate of removing Office than traditional methods. It will call the setup.exe and msiexec.exe to remove the previous bits. It is best equipped to deal with machine or software corruption, and completely removes the Office app shortcuts for the previous Office versions. It is recommended to use OffScrub in almost every situation of migrating from previous versions of Office. OffScrub is supported by Premier, whom you should contact to obtain the latest version for your specific Office deployment.
