Workdocs user invite getting expired within 2 days

Hello,

I understand you have sent the work docs invite to external users and the invites get expired in two days.

Below I would like to address your direct question--

Since it's optional to set an expiry date on the invitation link as shown here [1], the administrator is the one who can control if the link can expire or not ,so in this case , you need to send a new link with no expiration date.

i hope i was able to help.
