Disabling resharing

Hi,
Just a simple question.
we are planning to disable the resharing feature cause there’s a real issue when users use it extensively.
We have several cases of no longer active users that own some folders reshared several times and is a pain to reroute the

Is there a way to disable resharing in the user shares by default? like un-ticking the feature by default in the sharing menu?

And

If we disable resharing, The current reshares will dissapear? Is there a possibility to restrict the groups than can reshare?

Thats it.

Thanks

Uncheck “Allow resharing” in Admin settings.

Hi,

I think you will find out when you disable the feature like @ThomasMarx wrote.

@carlinux

Is there a possibility to restrict the groups than can reshare?

Unfortunately not. The only option going slightly into that direction is: “Exclude groups from sharing”, which means you could enter a group name here and users in these groups are not allowed to share anything at all.
Here are all the available sharing options:

I can’t risk messing with the current shares coz our users could build a guillotine for us…
I’ll set up a test enviroment to test.

That’s unconvenient.
I’m posting a feature request about that. I think is quite necessary since a rogue resharing chain could do a lot of harm and the feature itself is quite useful.
Thanks!

I’m posting a feature request about that.

Good idea! Could you post a link to the feature request here then? I would like to support that feature request.

When you find out about what happens with existing re-shares when you forbid re-sharing, please let us know here as well. I’m very curious about that.

Done

Reshare group permissions And/Or Force resharing permission Off in users shares

currently the reshare checkbox is just on and off but it should be possible to restrict the resharing option to groups to avoid uncontrolled resharing chains. I think is quite necessary since a rogue resharing chain could do a lot of harm, especially in enviroments with temporal users. As a alternative solution. It could be ok if the User share permission dialog untick the “resharing permission” by default. Thanks
