"Something went wrong" error when adding collaborators

Hi John, 

Welcome to the Box Community, I'm happy to help!

To confirm, are you trying to add multiple collaborators at once in a folder/ file? 

If yes, we have previously seen this error in the past when there were too many collaborators being invited at a time, and too many invites being made within a certain timeframe. This is expected behaviour, because of the measures Box has taken to protect our service. 

In order to resolve your situation we recommend that you decrease the amount of collaborators invited at a time and limit the number of invites sent per day. 

Hope this helps! Thanks for reaching out and let us know if you have questions.

Regards, 

Same error trying to add a single user.

Hi John, 

Can you try to logout from your Box account and then clear your browser cache, and then try this again?

Let us know how it goes and if you have questions.

Best,
