Provide an option to disable the "Share" button.
The Share button breaks inheritance on an item, and without warning to the user. With the default Permission Level of "Edit" in Team Sites, you can quickly have 100's or 1000's of items with unique permissions. Going forward, any permissions granted at the library or site level can create a situation where new users will see all of the content in a library, except for those with unique permissions.
I would like to be able to disable (hide) the Share buttons at various tiers such as library, site, site collection or web application/tenant.
Please add this feature to disable the Share button on all Site Collections. Would be nice to have a complete on/off switch to turn off and forget.
If we can't disable the share, it would be nice if we could change the default behavior for sending an email. Currently sending an email is the default, in our case we would like to force the user to select this option.
This is causing an issue when we try and have private folders for working groups! It's crazy that non admins can essentially share something with unique and restricted permissions! It negates the point of unique permissions. Microsoft need to sort their product out, unfortunately there isn't really any backlash on them for these sorts of things...which is also reflected in how bad their support service is.
As stated by Mike, Sharing breaks inheritance on an Item. This is bad on many different levels, but even Microsoft states the following:
Fine-grained permissions can influence security on a SharePoint farm. Potential performance issues can occur when you use fine-grained permissions. The following information helps you address issues when an environment is experiencing issues that incorrect use or scale of fine-grained permissions might have caused.
You can avoid fine-grained permissions by doing the following:
•Break permission inheritance as infrequently as possible.
So we as administrators want to disable sharing, which we can...sort of. Sure it makes it so you can't "Share", but the button is everywhere and still enabled. Why?!? I can even go to the details of an item with "read" permissions and I can see the option to "Manage access"? Selecting that I can choose "Gran Access" which brings up the "Share" option and I can choose someone who has no access to the site and choose to send them an email. I get no errors when I do this? So many things that can confuse end users and create tickets.
Yes please! This is something we realized after doing a recent security site audit. We have sites that have hundreds of documents that now have broken inheritance because of the sharing feature. What's the point of having site level security if we can break the inheritance with every document? At least lets have a default value for people with existing access since that's typically who people are sharing with. It's the only option missing from the SharePoint Admin centre.
SharePoint is not Facebook. When the act of "sharing" breaks inheritance, each time a folder, or document is "shared", it means at some point everything in the library will have broken inheritance. Add a new user and they will not see everything in the library! Such a terrible function. Share......ok, but breaking inheritance and changing permissions is really terrible planning. This needs fixed.
Using a modern page, I too for our company need the "Share" button to be disabled. We have web parts "Quick Links" "Events" and "People" They need Contribute permission on the home page to add content to these, which then enables the Sharing option, which is what we don't want users to do.
While I like the option of sharing, there are situations where we want the button to be disabled as well. I also agree that if you disable the option is "access request settings" that it should be disabled, and it's not. Very confusing to end users.
The SharePoint permissions model is just an utter mess and to think that it's been a mess since 2013 and they still haven't resolved it is shameful. Quite frankly the team need to stop focusing on the 'New Experience' UI and emojis and fix the permissions model, which can easily be fixed witha few simple tweaks. e.g. If Access requests Settings are turned off, truly disable sharing from Libraries and Word/Excel/ online which currently doesn't happen. Don't allow users to break inheritance by copying links etc too.
It's a really disappointing feature that was not thought through at all!
My company's management is understandably upset because the share button is still there even though I've disabled sharing. We have sensitive documents that we don't even want most of our internal members to see. This is a bad addition to SharePoint's new features.

Even when Sharing is turn off by the permissions settings, users still see a Share button in the web app. When you click the button you receive an inappropriate error message "Sorry, something went wrong"

Even after setting the Share options to off in Access Request Settings the UI option to Share still exists, it even exists for users who do not have permission to share (i.e. change permissions to) content - this is misleading and confusing to users, they should not be shown a button/option that results in a error message.

I have examples what can go wrong with the Share button here: http://techtrainingnotes.blogspot.com/2015/10/trick-or-treat-day-in-life-of.html
