Sharelink with external user + expiration

[Volt26]

Hello!

I have a Send an http request that sends a sharelink to an external user. This link has a feature I was looking for which is the code verification requirement without having to type your email.

Now I would like to set a specific expiration on this link (7 days). I tried to replace null with a specific date like "2023-02-05" or variables such as utcnow + add days (1) and none of my tried worked. Would someone here know what I'm doing wrong? The option is there and set to null so I guess there is a way to modify it, right?

By the way, thanks to this post I was able to get this far.

Hi @Volt26,

Can you try the value below for the 5th of Feb?

20230205T000000-0000

Just had a quick look in the Developer toolbar when setting this field with the 1st of March:

{"request":{"createLink":true,"settings":{"allowAnonymousAccess":true,"trackLinkUsers":false,"linkKind":5,"expiration":"20230301T000000-0000","role":2,"restrictShareMembership":false,"updatePassword":false,"password":"","scope":0}}}

Unfortunately I get this error (that I don't get when expiration is set to null)

Hi @Volt26,

You forgot the quotes around the value. Can you add those?

Oh this is great, I don't get an error anymore! The script works but there is an issue. After the link expires, the external user can still access the folder and write in it as if the link never expires..

Screenshot of the folder access BEFORE expiration (it was 10h57 and expiration was set for 11h00) :

At 11:01 I looked again at the access rights of the folder and here is what I see :

I logged on my other computer to make sure it had nothing to do with my member access (this 2nd computer never logs in there other than with an external link). This external user is still able to access the folder and upload files.

I think the script works. Maybe it is something that has to be done in the Sharepoint settings itself?

I noticed this :

So my guess is that to make it work, I probably need to follow this tutorial : New Expiring Access Policy to Control Guest Access to SharePoint Online Sites | Practical365 under the "Site-Specific Expiration Settings" section. Unfortunately I don't have the access to change that setting. I sent a request to our IT admin. I expect long delays before they even understand what I'm talking about.

Would someone know of another way? I guess there is none but it's worth asking.

Thank you very much Expiscornovus for giving me the answer!

Hi @Volt26,

I tried to reproduce your issue in my environment, but I was unable to. In my setup I have set the expiry date to 16:30 via a flow for an anonymous link:

{"request":{"createLink":true,"settings":{"allowAnonymousAccess":true,"trackLinkUsers":false,"linkKind":5,"expiration":"20230203T163000-0000","role":2,"restrictShareMembership":false,"updatePassword":false,"password":"","scope":0}}}

2. The interface shows this time for the anonymous link

3. When I navigate to that link in an in-private browsing session I get an expired message for the anonymous link at 04:31 PM (ignore the 08:31 AM, different time zone, lol)

Then you proved me it can work. It is most likely because the option isn't set by the admin. I'll wait for a reply from them... Thank you! I'll mark your answer as Accepted solution!
