An invitation belongs to one email address and can only be used once.

It was sent to a different account

• Traklist says the invite belongs to a different account, and shows which account you are signed in as.

• Choose Use Another Account to sign in as the invited address. The invitation is waiting once you do.

• Or choose Go to My Library and ask the owner to invite the address you actually use.

It was already accepted

• If you already joined, Traklist says the invitation has already been accepted. Open the folder from Shared under Shared with me.

• If someone else used it, Traklist says the invite was used by a different account. Ask the owner to send a new one.

You declined it

Traklist says you declined the invite to this folder, and that you should ask the owner to invite you again. Declining cannot be undone from your side.

It is no longer available

• Traklist shows Link Unavailable when the invitation no longer works.

• That happens when the owner withdrew it, the folder was deleted, or the invitation is too old.

• Choose Go to My Library, then ask the owner for a new invitation.

Note — This is different from a public share link that will not open. See Why a shared link may be unavailable for that.

Troubleshooting

If none of these match, confirm you opened the most recent invitation — an older one for the same folder stops working when a new one is sent. If the folder itself was removed, no invitation to it will open.
