"...In a Microsoft Tech Community blog post, the company writes that beginning October 2, Office 365 Home will see their device limits completely removed. That means instead of being limited to installing the software on a total of 10 devices, it's now an unlimited number of devices for both subscriber tiers.
Apps and services included with Microsoft Office 365Microsoft
The upgrade to unlimited devices applies to both Office 365 Home and Personal subscribers, the latter of which was previously limited to one PC or Mac and one tablet.
Microsoft is also increasing the number of licenses it provides to Office 365 subscribers. Office 365 Home, which requires a $99.99 per year fee, previously restricted users to a total of 5 unique users. Beginning October 2 Microsoft is adding an additional license. That makes the value proposition even more attractive considering each license also includes 1TB of Microsoft's OneDrive cloud storage.
Additionally, each license will be able to sign into 5 devices simultaneously. Yep, that means technically 30 devices at the same time for an Office 365 Home package.
All of these changes will not effect the current price structure, and the upgrade will be implemented automatically.
