You send someone a OneDrive link and they come back with a screenshot. Usually it says 'This item might not exist or is no longer available', with a second line: 'This item might have been deleted, expired, or you might not have permission to view it. Contact the owner of this item for more information.' Sometimes it is a page asking them to sign in or saying they need permission. Sometimes it is a link that worked last week and doesn't now.
That error text is very broad. It covers a deleted file, an expired link and a permission problem with the same message, so the message alone won't tell you which. The causes are few, though, and the person who owns the file can check every one of them in a couple of minutes. Start with three questions: did the link ever work, does it open for you in a private browser window, and are you on a work or school account?
- It worked before and now doesn't: the file was moved or deleted, or the link expired or was removed. See causes one and two.
- It never worked for them, but works for you: the link type or the account they are signed in with is the problem. See causes three and four.
- You can't create a working link at all, or options are greyed out: your organization's settings, sharing limits or Personal Vault. See causes four and five.
- It opens but there is no way to download: 'Block download' is on, or the file is over a download limit. See cause six.
Cause 1: The file was moved or deleted
Moving is the one people least expect. Microsoft's help says links will stop working if files or folders are moved within your OneDrive. Tidying up, reorganising folders or dragging a file into a new project folder is enough. The old link still points to where the item used to be. If a link you received no longer works, Microsoft adds, it may be that the owner has moved the file or stopped sharing the folder with you, and only the owner can fix that.
A deleted file takes its link with it too. Before you upload it again, check the recycle bin. Microsoft says personal accounts can restore files deleted within the last 30 days, and work or school accounts within the last 93 days unless the administrator changed the retention setting.
- Moved: go to onedrive.com, find the file in its new location and select its circle icon. Select 'Share' at the top of the page, then 'Copy link', and send the new link.
- Shared a folder and later moved new files into it: Microsoft says you'll need to share it again to make sure the new files are included.
- Deleted: on onedrive.com, select 'Recycle bin' in the navigation pane, select the file's circle check box, then select 'Restore'.
- Test the old link in a private window. If it still fails, create a new link from the restored file.
- Files deleted from the cloud, including online-only files, don't appear in your computer's Recycle Bin or Trash, so look in the OneDrive web recycle bin, not the one on your desktop.
- Once a file has been permanently deleted from the OneDrive recycle bin, Microsoft says it can't be restored. Upload it again and send a fresh link.
Cause 2: The link expired or was removed
Microsoft 365 subscribers can set an expiration date when they create a link. Microsoft is clear about what happens next: after the date you set, the link won't work anymore and you will need to create a new link.
On a work or school account, the expiry might not be your choice. Microsoft's admin documentation says an organization can require all 'Anyone' links to expire and set the maximum number of days. If the admin shortens that period, existing links update to the shorter setting, so links can stop sooner than you planned. Admins can also make guest access itself expire after a set number of days.
- Owner: select the file, select the Information icon in the upper-right corner to open the Details pane, then select 'Manage access'.
- To change an expiry, open the dropdown for that link and update or clear the expiration date.
- If the link isn't listed there any more, it was removed. Create a new one.
- If the link has a password, the recipient will be asked for it. Microsoft notes you need to give them the password separately.
Cause 3: The link only works for specific people
OneDrive offers several link types, and they behave very differently when forwarded. 'Anyone' gives access to anyone who receives the link, whether directly from you or forwarded by someone else. 'People in <Your Organization>' only works for people signed in to your organization. 'Specific people' gives access only to the people you named, and Microsoft says that if the invitation is forwarded, only people who already have access can use it. 'People with existing access' doesn't grant anything new at all.
So if someone opens a link meant for a colleague, or a link you sent to their work email while they are signed in to a personal Microsoft account, they get turned away. The fix is to check which link type you used, and which account they are signed in with.
- Owner, work or school account: if the recipient has no Microsoft account, they don't need one. Microsoft says OneDrive sends a one-time passcode to their email address, and they enter it to open the file.
- Owner, personal account: Microsoft says 'Specific people' links need the recipient to have a Microsoft account. If they don't, use 'Anyone' instead, which needs no account, passcode or sign-in.
- Recipient: open the link in a private or InPrivate window and sign in only with the address the file was shared with.
- For a known sign-in issue with shared folders, Microsoft's workaround is to sign in to onedrive.com first, then click the sharing link.
Cause 4: Your organization restricted sharing
On a work or school account, the admin sets the limits. Microsoft says your organization may have disabled the 'Anyone with the link' option to prevent usable links being forwarded to others. You can still create a link, but only people in your organization will have access. If a sharing option is greyed out, or 'Share' is missing from the right-click menu, Microsoft says your admins may have restricted it.
Restrictions can also reach links you already sent. Microsoft's admin documentation says that if external sharing is restricted or turned off, guests typically lose access within one hour of the change. Admins can also limit sharing to, or block, particular domains.
There is no setting on your side for this. Ask your IT admin whether the person or their domain can be allowed, and don't try to route around the policy.
Cause 5: Sharing limits, Personal Vault or a blocked account
Sometimes the problem is that you can't share at all. Microsoft's 'Unable to share OneDrive files' page lists these causes.
- Sharing limits: sharing is limited in basic or 'storage only' OneDrive. Microsoft says the limits reset after 24 hours, and a Premium subscription raises them.
- Account validation: if sharing emails won't send, Microsoft suggests validating your Microsoft account at account.live.com/reputationcheck and accepting the Terms of Use if asked.
- Personal Vault: items there are private and can't be shared. Move the file to a normal folder and share it from there.
- 'Your account is currently unavailable': Microsoft says an account can be temporarily blocked for unusually large traffic volume, suspicious activity or a terms violation. If you shared a large number of files, the block is removed within 24 hours.
- OneDrive not running: you can't share from File Explorer or Finder, but you can still share from onedrive.com.
Cause 6: It opens, but it won't download
If the file opens but there is no way to save it, the owner may have ticked 'Block download' in the link settings. Microsoft notes that option is only available on work or school accounts, and only when editing isn't allowed. The owner can untick it in the link's settings, or the recipient can ask for a new link.
Very large downloads have their own limits. Microsoft lists a 250GB file size limit for downloads, and when you download several files at once as a .zip, a limit of 10GB per .zip file and 20GB overall. Microsoft also says you can't download files directly from the 'Shared' view; open the file and save a copy instead.
Prevent it next time
Put a file where it will live before you share it, because moving it later breaks the link. Choose the link type on purpose: 'Anyone' for people outside your organization who just need to open it, 'Specific people' for anything private. If you set an expiry, tell the recipient the date. And test every link in a private window before you send it; if it opens there, it will open for them.
When it is a one-off handover
If you just need to get a file to someone once, OneSol Send (onesol.io/send) uploads up to 5 GB per transfer and gives you one link that recipients download without an account; you need a free OneSol account to send. Files delete themselves after 24 hours, so it suits a quick handover, not long-term storage.
