If you created a link that isn’t working, check the following:
1. Did you delete the file or folder?
To reenable the link, restore the file or folder. As soon as you restore the file or folder, the shared link will work again.
2. Did you disable the link?
Follow these steps to check if your link is disabled:
3. Has the link expired?
4. Is the file in a shared folder? Did the owner change its settings?
If you're a Dropbox Business user, the owner of a shared folder may have changed the sharing settings to specify that links can only be shared with other team members. The admin can also turned off the ability to share links with people outside the team.
5. Were your links banned?
If you received a link that isn’t working, check the following:
1. Does a shared link open in your Dropbox account?
If you already have access to a file or folder (in other words, if the file owner shared it with you before), clicking a shared link takes you directly to your Dropbox. This works for folders too: if you already have a folder in your Dropbox, clicking a shared link that points to that folder takes you to its location in your Dropbox.
2. Does a shared link fail to open in your browser?
If you click a shared link and it fails to open, you may be encountering a browser issue. To correct this, sign out of Dropbox and then click the shared link again.
3. Is the link still not working?
If neither of these fixes the issue, contact the person who created the shared link.
If you received an email notification about a shared folder or shared link, make sure the email really came from Dropbox. If it's not genuine or you're not sure, don't click any links in the email.
Forward the suspicious email to firstname.lastname@example.org and we'll investigate.
Even if the notification came from Dropbox, don't view or download a file, or accept a shared folder invitation, unless you know the sender. If you don't know the sender, ignore the notification, delete the email, or decline the invitation.
