I received this from the “OneDrive Team” today:
“Changes to OneDrive
We recently announced some changes to OneDrive. On July 27, 2016, the free storage that comes with OneDrive will change from 15 GB to 5 GB. We are also discontinuing the 15 GB camera roll bonus.
These changes are rolling out to our free and new users. However, because you have purchased an additional storage plan, your account will not be affected by these changes, and there is no action you need to take. The price and details of your storage plan are not changing at this time, and as long as you keep your current paid plan, you will keep your current storage.*
Thank you for using OneDrive.
– The OneDrive Team”
Well, looks like free account users are going to experience a reduction of storage soon… I do not know yet if you have 15GB used, if they will make you purchase or reduce, that remains to be seen.
