Remove a Collaborator Governance Action is not working

Brass Contributor

Hi Community,

 

I created a File Policy with a Governance Action to remove a specific user as a collaborator but it does not take effect. Scenario:

1. Create a File Policy that matches all files in OneDrive and SharePoint that has an access level of external and has collaborator user@contoso.com.

2. Configure Governance Action to remove the collaborator user@contoso.com .

3. I can see alert for all the files that has matched the policy.

4. When I click on "View policy matches" > History I can see Actions --- Remove a collaborator is applied to those documents.

5. When I go to Investigate > Files and filter for all documents with collaborator user@contoso.com I can still see those documents with the collaborator user@contoso.com on it.

 

I have been waiting 2 days for the policy to take effect. 

 

Hope someone can enlighten me on this.

 

Thank you!

Hi, I just tested this scenario, and it looks like the policy does not automatically remove the collaborator.  In my test, I had to highlight one of the files, go to actions, and then select Remove a collaborator as shown below;

This succeeded in removing the collaborator from the file.  Not a specific scenario of CAS I have tried before, but it looks to me like this may be the intended behaviour - IE, the policy matches and Investigate Files will show you the external collaborators - but then you have to explicitly remove the access.

@PeterRising thank you for your response!

 

We are intending to do this to remove the permissions to external users. I believe that Governance Action should be a real time action once an activity has matched that policy.

Should this be automated?

@Mary_Yvette 

 

Yes I agree that it should be automated as per the guidelines in the link you provided.  Thus far, I cannot get it to automate the removal of a collaborator though - the same as you are facing.

 

What do you see if you click the cog wheel and select Governance log?

The Governance action for removing Collaborator is not listed there. But I can see the alert has been triggered.

@Mary_Yvette 

 

I'm working on this some more but have not succeeded in generating automated governance as yet.  I will let you know if I figure this out.

@Mary_Yvette 

 

In my continued testing, I cannot get automated governance to take the action to remove the collaborator.  However, if I change the action to Remove External users, it works, and removes all external users.

Weird that it does not do the same for collaborator though. I may open a ticket with Microsoft about this and see what response I get.

Thank you for all the testing!

 

Raised this to MS Support and according to them it only works if the user has been added as a Direct Access not a shared link or the usual sharing that we do where we specify a specific user when sharing.

I really hope Microsoft would also support the remove collaboration when using the usual sharing.

Hi Mary, thank you for this information.  This is really handy to know.  I agree that this functionality is not ideal.  I have logged with Microsoft myself.  I am sure they will tell me the same thing.  I will let you know if otherwise.  :smile:

@Mary_Yvette 

 

Ha, MS support actually referred me back to this post.  :lol:

I guess we have our answer on this.

Thank you for the help @PeterRising :lol:
