No.
Are you talking about OneDrive cloud based storage from MS ?
MS offers 501(c)(3)'s "charity" licenses at bargain prices. As I recall, Server 2012R2 Standard cost the church about $100. Server CAL's were only a couple of dollars each.
The only reason, I mention Windows Server, is that some organizations are looking for a cheaper (free) alternative and end up looking at FreeNAS.
I bought all their MS licenses: server, desktop OS upgrades, Office ProPlus, etc. via the open license plan. When Office 2013 cost my workplace $300+ for a license, the church was paying about $70.
I led church IT as a volunteer for 27+ years. About 18 months ago, the church administrator blindsided me by hiring someone for $95/hour to do the work I was doing for free (without even offering it to me). I'm an IT Pro with 30+ years of experience. They even had the audacity to try to get me to help (for free) the contractor diagnose new problems that he had created. I gave them the keys to the store and quit.
Enough about Windows - this is the FreeNAS forum.
FreeNAS has a number of features, including the use of software RAID. No need for a hardware RAID controller or the concern that if a hardware RAID controller fails, you need to source an identical one. ZFS is a great filesystem.
If you decide to go this route, please look at the resources section of the forum. Read the documentation and ensure that your "server" meets the requirements.
