To send a large file with OneDrive: upload it to onedrive.com (or your OneDrive folder), right-click the file, choose Share, set the link to "Anyone with the link", and send that URL. OneDrive accepts individual files up to 250 GB, so size is rarely the problem — the friction is quota, permissions, and what the free tier leaves out. Here is the clean way to do it, the traps, and when a dedicated transfer link works better.
Step by step: share a large file from OneDrive
- Upload the file to OneDrive — via the website, the sync folder, or the mobile app. Very large uploads are far more reliable through the desktop sync client than the browser.
- Right-click the file → Share.
- Click the link settings and choose "Anyone with the link" — otherwise recipients outside your organization will hit a sign-in wall.
- (Microsoft 365 subscribers only) Optionally set an expiry date or password on the link.
- Copy the link and send it by email or chat.
In Outlook, attaching a file larger than the ~20 MB message limit triggers the same machinery automatically: Outlook offers to upload it to OneDrive and share a link instead of attaching.
OneDrive's actual limits
| Limit | Value | Notes |
|---|---|---|
| Max single file | 250 GB | Applies to uploads via any method |
| Free storage | 5 GB total | The real ceiling for free users — one video fills it |
| Microsoft 365 Personal storage | 1 TB | ~$7/mo, includes Office apps |
| Link expiry / password | Paid plans only | Free links live until you manually remove them |
| Download notifications | Not available | No alert when someone downloads your file |
The three traps people hit
- The 5 GB free ceiling: OneDrive's free tier holds 5 GB total — a single phone video can consume it. "Send a large file" quietly becomes "buy Microsoft 365".
- Permission walls: if the link setting stays on "People in your organization" (a common default), outside recipients get a sign-in prompt instead of your file. The support emails write themselves.
- Files linger forever: shared files sit in your quota and stay accessible until you remember to unshare them. Free links have no expiry option, no password, and no download log.
When a transfer link is the better tool
OneDrive is excellent when the file should live somewhere — synced, versioned, collaborated on. When the file just needs to arrive somewhere, a purpose-built transfer link is cleaner: upload at everytransfer.com with no account, get a link that downloads for anyone in any browser with zero permission dialogs, add a password and expiry on the free tier, and get notified the moment it is downloaded. Nothing accumulates in a quota — expired transfers clean themselves up. The same logic applies to Google Drive, which we cover in our Drive comparison.
Can I send a 100 GB file with OneDrive?
Yes, if you have the storage: 100 GB fits under the 250 GB per-file cap but requires a Microsoft 365 plan (1 TB included). Upload via the desktop sync client for reliability, then share with "Anyone with the link". Alternatively, a transfer service with resumable chunked uploads handles the same file without the subscription — and tells you when it lands.
Why can't my recipient open my OneDrive link?
Almost always the link scope: it was created as "People in [your org]" or "Specific people", and the recipient is signed into a different Microsoft account (or none). Re-share with "Anyone with the link", or send the file through a channel with no account concept at all — a transfer link downloads for literally anyone who holds it, with an optional password as the gate.
