Back in November, Microsoft announced that the company will reduce the free storage limit for OneDrive. If you are an old OneDrive user, your 15GB of free storage would also get reduced to only 5GB. Thankfully though, Microsoft allowed existing OneDrive users to retain their free 15GB of OneDrive storage.
The offer will end on 31st of January and this article is just a friendly reminder for that. So if you are yet to claim your free OneDrive storage, make sure to claim it here.
