Hello,

I am currently trying to give external users access to several folders in our Box account, but when I try to send them an invitation, it will not go through.

I am the owner of the folders and a co-owner of the Box account. I have also tried checking the invitation restrictions in the folder settings, but I am unable to check or uncheck the “Restrict collaboration to within _____” option. I asked the account owner to try as well, but they are unable to change the setting either.

How can I give external users access to these folders? Is there an account-level restriction that may be preventing us from changing this setting?

For context, these external users already have access to other folders within our Box account, so they are able to collaborate externally with our account.

Thank you!

Hi ​@OAJ, 

Welcome to Box Community, and we will help you modify this setting to allow external collaboration to your folder! 

 

If the setting cannot be disabled in the folder settings. Try checking the folder owner’s profile in Admin Console. 

 

Review if your Box account is restricted to collaborate with external users: 

  1. Log in to Box.com and navigate to Admin Console> Users & Groups. 
  2. Look for the folder owner’s name and click to display his/her profile. 
  3. Scroll down to Role and Access Permissions and see if Restrict External Collaboration is enabled. 
  4. If enabled, click “edit” and toggle to disable it then Save. 

 

Hope it helps! Let us know how it goes.

Hello Rona,

I have navigated to the Admin Console and gotten to where I see the Role and Access Permissions under the folder owners name. I do see that next to Restrict External Collaboration this shows “Enabled external collaboration restriction on files and folders users own”. However, I do not have the option to click “edit” in this section. 

 

I also tried to go to the external users profile and go to Folder Collaborations and edit their permissions. This allows me to select the folders and make them editors, and I click save but when I go back into our Box Account, they do not have access. When I tried to then share it with them, I still receive the message “Invitations could not be sent to the following people because external collaboration is restricted by either your or their enterprise: ____”

Do you have any other ideas on how to fix this? 

Thank you!

Hi ​@OAJ, thank you for checking! 

Apologies, we forgot to mention that as Co-Admin like yourself don’t have permission to make changes in your account setting such as lifting the ‘Restrict External Collaboration’ in Admin Console. 

 

Instead, you must reach out to your primary Admin to disable it. Once it's disabled, each folders you own can now be shared with external collaborators, unless they are modified in the folder setting. 

 

We hope to get this sorted out soon! Let us know your thoughts.

I am receiving the error: "Invitations could not be sent to the following people because external collaboration is restricted by either your or their enterprise".

I’ve looked at our settings and see that "Restrict external collaboration" is enabled either in the folder settings. I followed these steps: 
In folder settings:

  1. Hover your mouse to the folder in question
  2. Click More options(...)
  3. Click Settings from the dropdown menu
  4. In Invitation Restrictions section, see if the setting "Restrict collaboration to within..." is checked. If it is, uncheck it and save the changes.

However, the setting is greyed out so I am unable to uncheck it. 

 

Any advice? Thank you!

Hi ​@jhoffmann, thank you for joining the Box Community!

We moved your post to this related topic, please don’t hesitate to join our discussion. 

 

If you couldn’t disable this setting at a folder level, review the folder and check the owner. Is the owner part of your organization? If she/he does,  confirm if the external collaboration is restricted in the account settings. 

 

Review if your Box account is restricted to collaborate with external users: 

  1. Log in to Box.com and navigate to Admin Console> Users & Groups. 
  2. Look for the folder owner’s name and click to display his/her profile. 
  3. Scroll down to Role and Access Permissions and see if Restrict External Collaboration is enabled. 
  4. If enabled, click “edit” and toggle to disable it then Save. 

To accomplish this change, please reach out to your Box primary admin. 

 

Hope it helps! Let us know how it goes.

Hi,

Thanks so much for the reply. The owner of the folder is still at the organization and has an active Box account with an “Admin” role. I am unable to look at their profile because it is greyed out so I can’t see the Role and Access Permissions setting. However, on my profile (co-owner of the folder and co-admin) but there aren’t any toggle settings that I see.
