TL;DR: OneDrive is your own space and SharePoint is the team’s space. That one rule solves most Microsoft 365 file chaos. Anything more than one person touches belongs in SharePoint or a Teams channel, which are the same storage. Keep drafts and personal work in OneDrive. Files left only in a personal OneDrive get hard to reach when that person leaves, and files left only on a laptop aren’t protected at all.
If your business runs on Microsoft 365, you have two places to store files, and most people were never told which is which. So files land wherever is easiest: OneDrive, SharePoint, Teams, and the laptop desktop, with no rule connecting any of it.
That’s where the everyday headaches come from. A file nobody can find. A document only one person can open. A scramble to recover somebody’s work after they’ve already left.
The OneDrive vs SharePoint question sounds like an IT detail, but it isn’t. It decides how easily your team finds things, what happens when someone resigns, and whether you can recover a file that got wrecked. And the rule for getting it right takes about ten seconds to learn.
What’s the Difference Between OneDrive and SharePoint?
OneDrive is your personal space and SharePoint is the team’s shared space. Think of OneDrive as the cloud version of the My Documents folder on your computer: your files, private to you unless you deliberately share them. SharePoint is built for documents with shared ownership, the ones your team, department, or whole company works on together.
Microsoft’s own guidance is about that blunt. If you’re working on something by yourself, save it to OneDrive. If you’re working as a team, save it where the team works.
The distinction that matters for a business owner is ownership, not features. A file in OneDrive belongs to a person. A file in SharePoint belongs to the company. Everything downstream of that, including access, sharing, and what happens when someone leaves, follows from which one you picked.
Where Do Teams Files Actually Get Stored?
In SharePoint. Every team has a SharePoint site behind it, and the Files tab in a Teams channel is just a window into that site. Uploading a file to a Teams channel and putting it in SharePoint are the same action.
This confuses a lot of people, because Teams looks like a third storage location sitting alongside the other two. It isn’t.
If your team works in Teams, your shared files are already in SharePoint whether anyone realized it or not. That’s good news. It means those files have shared ownership and don’t depend on one person’s account staying active.
So Where Should Your Files Live?
Three rules cover almost every situation. Your own drafts and personal work go in OneDrive. Anything more than one person touches, including client and project files, goes in SharePoint or the relevant Teams channel. And nothing important lives only on a laptop desktop.
That third one deserves emphasis. A file saved only to a local desktop isn’t shared, isn’t backed up, and disappears with the laptop. It’s the single most common way small businesses lose work, and it has nothing to do with hackers.
You don’t have to change how you work to fix it. The OneDrive app keeps a copy of your files on the device for offline use and syncs your changes up automatically. You still open things from File Explorer the way you always have. The difference is that a copy now exists somewhere other than that one machine.
Sharing: Why the Location Changes Everything
When you share a file out of your OneDrive, you’re inviting people into your personal space with a link tied to your account. It works, right up until it doesn’t. If you leave the company or the file moves, those links can break, and whoever was relying on them is stuck asking around.
In SharePoint or a Teams channel, the right people already have access because the files belong to the team. You point a colleague at the folder and they’re in. No one-off links to track, no forwarding a link to someone who then forwards it to someone else.
One more habit worth teaching: share a link, not an attachment. When everyone opens the same file, everyone sees the current version. Email a copy and you end up with five slightly different versions attached to five different emails, and no reliable way to tell which one is right. That’s a small thing that quietly costs real hours, and it’s the kind of habit worth covering in team training alongside the security material.
What Happens to Files When Someone Leaves?
You get a short window and then it gets difficult. When you delete a user, Microsoft keeps their OneDrive for 30 days by default and gives their manager access to retrieve what’s needed. After that it moves to a recycle bin for 93 days, where recovering it requires PowerShell and an administrator.
There’s a catch most businesses don’t discover until it bites them. That automatic access goes to the departing person’s manager, or to a designated secondary owner. If neither is set in your tenant, nobody gets automatic access at all, and you’re straight into the administrator recovery path.
The retention window is adjustable, up to 3,650 days, but almost nobody changes it because almost nobody knows it’s a setting. Two minutes now saves a bad afternoon later, and it’s exactly the kind of thing a managed IT provider should have configured on day one.
None of that is a problem for files in SharePoint. Those stay with the team no matter who comes or goes. That’s the real argument for the rule: not tidiness, but the fact that offboarding stops being a rescue mission.
Version History Is Not a Backup
Both OneDrive and SharePoint keep older versions of files and a recycle bin, so an overwritten document or an accidental delete is usually recoverable. If ransomware scrambles a library, version history is often what gets you back to a clean copy without starting over.
Use it. Just don’t mistake it for a backup.
Version history protects against mistakes inside a working system. It doesn’t protect against a retention window expiring, a deliberate mass deletion, or a compromised administrator account. Microsoft’s own service agreement puts responsibility for your data on you, and that’s the gap proper backup and recovery fills for Microsoft 365. A lot of small businesses assume the cloud handles this and never find out otherwise.
Fix This Without a Migration Project
Three things to take away. OneDrive is one person’s space and SharePoint is the company’s. Teams files already live in SharePoint, so if your team works there you’re most of the way home. And the files that cause real pain are the ones sitting only in a personal OneDrive or only on a laptop.
You don’t need a big project. Pick your most important shared folder, move it into SharePoint or a Teams channel, and write down one sentence everybody agrees on, like “client files live in the client’s SharePoint folder.” Then check that your tenant has a secondary owner set for departures.

Frequently Asked Questions
What’s the difference between OneDrive and SharePoint in one line?
OneDrive is for your own work files. SharePoint is for files your team shares. The practical difference is ownership: a OneDrive file belongs to a person, a SharePoint file belongs to the company.
Where do files in a Teams channel get stored?
In SharePoint. Every team has a SharePoint site behind it, and the Files tab in a channel is a view into that site. Uploading a file to Teams is the same as putting it in SharePoint, which means those files already have shared ownership.
Should I keep work files on my computer’s desktop?
Not for anything important. A file saved only to a desktop isn’t shared, isn’t backed up, and is gone if the device is lost or fails. Save it to OneDrive or SharePoint instead. The sync app still keeps a copy on the device, so you can work the same way you always have.
What happens to files in someone’s OneDrive when they leave?
Microsoft keeps a deleted user’s OneDrive for 30 days by default and grants their manager access, and that window can be extended if it’s configured in advance. After it expires, recovery moves to an administrator process with a hard deadline. It’s far easier if the shared work was in SharePoint to begin with.
Can I get back a file that was deleted or changed by mistake?
Usually. OneDrive and SharePoint both keep a recycle bin and older versions, so you can restore a deleted file or roll back to an earlier one. That covers mistakes, not every scenario, which is why a separate backup still matters for a business.
