Why did my shared link stop working?
If a link you've shared has stopped working, check the following:
Make sure the file or folder hasn't been deleted. To re-establish the link, restore the file or folder. As soon as you restore the file or folder, the shared link will work again.
Make sure you haven't disabled the link. Sign in at dropbox.com and click Links in the left-hand sidebar. If you don't see the link in your list, you may have removed it at some point. You can always create a new link to the file of folder you want to share.
Make sure the link hasn't expired. If you're a Dropbox Pro or Dropbox Business user, and you set an expiration for your shared link, it may have expired. In that case, you need to create a new link to the file or folder.
Check with the shared folder owner. If you're a Dropbox Business user or a team 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 (and not externally).
Check with your admin about your team's sharing rules. If you're a Dropbox Business user, your admin may have turned off the ability to share links with people outside the team. If so, shared links that you've created won't work for people outside the team unless your admin turns this permission back on.
If you have specific questions about why your link was banned, or how long the ban is for, contact Dropbox support.
Too many invitations
If you're a Dropbox Basic user who is creating shared links, you may get the error message You are trying to share with too many people at once. This means that you surpassed the daily limit for shared folder and link invitations. The limit resets daily, so try to share your files the next day.
Important note on copyrighted material
You should only use shareable links for files that you have the legal right to share with others (for example, documents, photos, software, music, and videos that you personally created). You do not have the right to share files unless you own the copyright in them or have been given permission by the copyright owner to share them. Purchasing or legally acquiring video, music, ebooks, or software does not give you the right to share that material with third parties over the Internet.
If you have any doubts about whether you have the legal right to share certain files, you should not share them. You represent that files shared using shareable links do not violate Dropbox’s Terms of Service and that you own all copyrights to them or have been given permission by the copyright owner to share them. Dropbox has adopted a policy of terminating the accounts of users who repeatedly infringe copyright or whose accounts are subject to multiple infringement allegations. If you repeatedly share files that infringe others’ copyrights, your account will be terminated.
