Microsoft Is Using Its Other Android Apps to Prompt OneDrive and PowerPoint Installs

Users who have installed Microsoft's Your Phone or Word apps are seeing ads for PowerPoint, Excel, and OneDrive when opening related documents or trying to share most filetypes.


has been caught using underhand tactics to get users to install its Office apps. As noticed by Android Police, opening .pptx files on 's platform will prompt an install of PowerPoint, even if Slides is already installed.

This behavior appears to originate from the Companion app and has been present since April. At that point, Your Phone mirroring was in beta and the future was unclear.

Microsoft's companion app initially acted as a hub for all its apps, showing which users had installed. It was previously known as ‘Microsoft Apps' for this reason. However, the company introduced a degree of cross-platform functionality between Windows and Android with the Windows 10 April 2018 update. At this point, the app switched to Your Phone branding but kept the app hub functionality.

Your Phone is now out of beta and required for Android mirroring/syncing. With it installed, if you attempt to open a PPTX file without Slides, you'll go straight to the PowerPoint download page, otherwise, you'll get a choice between Slides or a PowerPoint install. If you set Slides as the default, you'll no longer get this prompt. As well as Your Phone, this happens when you install the app.

In our testing, we noticed similar behavior for .docx files and Word, .xls files and Excel, and other file such formats. It doesn't seem to happen for most non-Microsoft formats, such as .odt and .txt, though Excel is a recommendation for .mhtml files.

Persistent OneDrive Ads

In all, this part of Microsoft's tactics isn't too much of a concern. Once they set a default, users won't have to worry, and prompts only seem to appear when they're actually useful.

When it comes to the OneDrive, Your Phone presents much more intrusive behavior. When trying to share images, documents, or other common file types, users will get a OneDrive install option. Obviously, this adds a little more clutter to the user's share menu if they don't want the app.

Admittedly, it's a minor annoyance, but it also feels like Microsoft is piggybacking off Android's functionality in shady ways. App developers could end up using this to push unrelated app installs and degrade user experiences.
