Here is a question I ask new clients, and it usually gets a long pause. When someone leaves your business, what happens to the files they were working on? The answer depends entirely on where those files lived, and that is what the SharePoint versus OneDrive question is really about. Not features. Where things go when people come and go.

If your business runs on Microsoft 365, you have both. Almost nobody was ever told the difference, so files end up wherever was easiest at the time: some in OneDrive, some in SharePoint, some in Teams, and a fair number on the desktop of one laptop. Then a file cannot be found, or only one person can open it, or someone leaves and the scramble starts. The muddle over where things belong is what causes it.

I want to teach the difference plainly, then give you three rules that settle it.

SharePoint vs OneDrive: what each one is for

OneDrive is your own space. Think of it as the cloud version of the My Documents folder on your computer. Your drafts, your working files, private to you unless you choose to share something. It belongs to your account.

SharePoint is the team’s space. It is built for files with shared ownership, the documents your department or the whole business works on together. It belongs to the business, not to any one person’s account.

Microsoft’s own advice is simple. Working on something by yourself, save it to your own space. Working as a team, save it where the team works.

That is the whole distinction, and it is about ownership, not storage. Both are cloud storage. Both back up. Both keep old versions. The difference is whose name is on the door.

Where Teams fits, because it confuses everyone

Microsoft Teams looks like a third place to keep files. The Files tab is right there in every channel. People upload things to it all day.

It is not a third place. When you put a file in a Teams channel, it is stored in that team’s SharePoint site. The Files tab is just a window into SharePoint. Same file, same folder, two ways in.

So if your team already works in Teams, your shared files are already in SharePoint whether you knew it or not. That is good news. It means they have shared ownership and do not belong to one person’s account.

The flip side is worth knowing. Files you share in a private chat, one person to another rather than in a channel, go into the sender’s OneDrive. That is why a file somebody sent you in a chat months ago can vanish when they leave. It was theirs, not the team’s.

What actually happens when someone leaves

This is the part that makes the difference matter, so I will walk through it in order.

An employee gives notice. On their last day, their Microsoft 365 account gets disabled, or should. Everything in their OneDrive is still tied to that account.

By default, Microsoft holds a deleted user’s OneDrive for 30 days and gives their manager access. That sounds fine until you are the manager. You now have 30 days to open someone else’s file system, figure out what in there mattered, and move it, while also doing your own job. Nobody knows what was in there until it is already gone, and that is the honest version of how it usually plays out.

Files in SharePoint do not go through any of that. The team still owns them. The person left; the folder did not notice.

We see the aftermath of this around Beaumont and League City more than you would think. The quote template lived in the estimator’s OneDrive. The vendor contact list lived in the office manager’s OneDrive. They left, the account was closed, and six weeks later somebody needed the template. I will say plainly that the 30 day window can be extended, but only if it was set up in advance, and it almost never was. Our post on why messy offboarding starts with bad onboarding covers the rest of that story.

Three rules that settle SharePoint vs OneDrive

You do not need a policy document. You need three sentences everyone can repeat.

Rule one: if only you need it, OneDrive. Drafts, notes, the spreadsheet you are still building, the personal copy of something. Your own space is fine, and it is meant for exactly this.

Rule two: if the business needs it, SharePoint. Any file more than one person works on, any client or project file, any template, any list the office runs on. It goes in SharePoint, or in the Teams channel for that work, which is the same thing. The test is simple. If this person quit tomorrow, would somebody else need this file? Then it is not theirs.

Rule three: nothing important lives only on a desktop. A file saved only on a laptop is not backed up, is not shared, and is gone when the laptop is. This is the rule people push back on, so here is the thing they did not ask about but need to know: the OneDrive app keeps a copy on the computer for offline use and saves changes to the cloud automatically. You keep working exactly as you do now. The file is just also somewhere safe.

Sharing files the right way

Where a file lives also changes how you share it, and this is where a lot of the everyday friction comes from. The choice decides who can reach a file without asking.

When you share a file from your OneDrive, you are sending people into your personal space with a link tied to your account. It works. But the link depends on you. If you leave, or the file moves, the link dies, and whoever relied on it is stuck.

In SharePoint or a Teams channel, the right people already have access because the files belong to the team. You point a coworker at the folder and they are in. No one-off links to manage, no “can you reshare that.”

And share a link instead of emailing a copy. When everyone opens the same file in the cloud, they are all looking at the current version. Emailing a copy is how you end up with five slightly different versions of the price list attached to five different emails, and nobody sure which one is right. I see this in nearly every business we onboard.

How we set this up for clients

When we bring a new business onto Microsoft 365, this file question is one of the first conversations, because it is much easier to set up right than to untangle later.

We build the SharePoint structure around how the business actually talks. Clients around here do not say “document library.” They say “the accounting drive” and “the shared folder.” So that is what the folders are called. One for the office, one for each department that needs its own, one for clients if the business is organized that way.

Then we set the OneDrive app up on every computer so the Desktop and Documents folders sync automatically. That takes care of rule three without anyone having to remember it.

Last, we write down the rule in one line and put it where people will see it: client files live in the client’s SharePoint folder. That one line prevents most of the confusion.

The one thing I will add, because it is the part nobody asks about: both OneDrive and SharePoint keep older versions of every file and a recycle bin. If a document gets overwritten, or ransomware scrambles a folder, you can roll back to a clean copy. That protection only helps if the file was in one of them to begin with. It does nothing for the file on the desktop. Our SharePoint services page covers the setup side if you want the detail.

Frequently asked questions

What is the difference between SharePoint and OneDrive in one sentence? OneDrive is for your own work files. SharePoint is for the files your team shares.

Where are files in a Teams channel 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 to Teams is the same as putting it in SharePoint.

What happens to someone’s OneDrive when they leave? By default Microsoft keeps it for 30 days and gives their manager access. That can be extended if it was set up in advance. It is recoverable, but it is far easier if shared work was in SharePoint to begin with.

Should I keep work files on my computer’s desktop? Not anything important. A file only on a desktop is not shared or backed up. Let the OneDrive app sync the desktop so it is protected without changing how you work.

Can I get back a file that was deleted or changed by mistake? Usually, yes. Both OneDrive and SharePoint keep a recycle bin and older versions, so you can restore a deleted file or roll back to an earlier version.

Do I need SharePoint if I have OneDrive? If more than one person in the business works on files, yes. OneDrive was never meant to be the company file server, and treating it as one is what causes the problems above.

If you are not sure where your own files live, or you suspect the answer is “everywhere,” we can look at how your Microsoft 365 is set up and tell you plainly what is where. That is part of what we cover in the More365 review, which is about getting the full use out of what you already pay for.
