Your Dropbox link works for you and not for them

You've sent a Dropbox link to a customer. It opens straight away for you. They say it asks them to sign in, wants them to request access, or shows a page that never loads the file.

You're testing signed in as the file's owner, or as a member of the team it belongs to. Dropbox is letting you in because of who you are, not because of the link itself — and your buyer is neither of those people. The only way to see what they see is to stop being you.

The setting that actually causes it

On a paid Dropbox plan, every shared link has a Who has access setting: “Anyone with link”, or “Team members”, which limits it to people inside your Dropbox team. A buyer isn't in your team, so a link left on Team members won't open the file for them.

Fix it in the share dialog

1. 1

   Share the folder, not the individual files

   One setting on the folder covers everything inside it, rather than thirty individual files where one gets missed.

2. 2

   Set access to “Anyone with link”

   Open the link's Manage settings and change Who has access away from the team-restricted option. This is the fix for almost every version of this problem.

3. 3

   Use “Link for viewing”, not “Link for editing”

   Dropbox's own instructions: “Select Link for editing for a link with edit access. Select Link for viewing for a link with view-only access.” A viewing link lets a buyer see and download; an editing link lets anyone with it alter or delete your master files.

Then test it as a stranger

Changing the setting isn't enough to know it worked, because you still can't see what a signed-out visitor sees while you're signed in.

If the incognito window opens it cleanly, your buyers will too. Google Drive and OneDrive fail the same way with different menu names — the same private-window test catches all three.

The other two settings worth checking

• Password. Dropbox: “When someone opens the link, they'll need the password to see its contents” — fine for sending something privately, unhelpful for a link that's meant to open on its own the moment a buyer taps it. Leave it off unless the delivery page you're using is the one place the password is shown.
• Expiration date. Dropbox: “People can access the shared link only until the expiration date. After the expiration date, the link is disabled.” An expired link “will stop working, but you can re-enable it by editing the expiration date” — worth checking first if a link that worked for months suddenly fails for every buyer at once, rather than assuming the sharing setting itself broke.
• Downloads disabled. Dropbox: with downloads off, “Recipients can preview the file on dropbox.com, but the Download button will be grayed out and won't be clickable.” A buyer who can see the file but not save it has effectively been sold nothing.

The failure that costs the most

It's rarely the link that never worked — a buyer messages you and it gets fixed. It's the link that worked for months and then stopped, usually because the file or folder was moved, renamed or deleted during a tidy-up, or a team admin's sharing policy changed underneath it.

• Never move or rename a folder you've shared in a live product. Create a new one and share it again instead.
• Keep product files in a folder separate from your everyday working files, so a routine tidy-up can't touch them.
• Re-run the incognito test on live products every few months, not just when you first set them up.
• Better: don't put the raw Dropbox URL in front of buyers at all — see below.

Putting a link you control in front

The structural fix is the same one that applies to Drive, OneDrive or Canva: don't hand buyers the raw Dropbox URL. Give them a short link you own that points at the folder. If the destination ever needs to change, you repoint the short link once, instead of finding every past buyer to resend a working file.

That's what AccessDrop does with a Dropbox link exactly as it does with Drive, OneDrive or Canva: you paste it in, and it produces a branded delivery PDF with a QR code and a short link — checking first whether the link opens without signing in. For Dropbox that check spots a redirect to Dropbox's own sign-in page and an edit-access link URL; treat it as a first pass, not a substitute for the private-window test above, since a team-restricted link can fail in a way the check doesn't yet recognise.

£19 for a year, one payment, up to 5 deliverables. It doesn't host the files — Dropbox still does — it makes the handover reliable and keeps checking that it stays that way.
