We recently enabled SSO on BOX, which has interfered with the ability for users to log-in using their personal emails associated with a shared email address (Added under "Other Emails" on "Edit User Account Details").
After enabling SSO, these users could no longer log-in as they didn't have their own BOX accounts. I had to delete from the "Other Emails" and add them as users. I am unable to re-add these users "Other Emails"; I receive an error that reads "There was an error while trying to add abc@email.com to your account".
How should I proceed? I have already added all of the users as co-owners to all of the files from the shared account, but they are unhappy that they cannot log into the shared account itself. Do I have to add the shared account to our SSO provider OKTA then ask them to share a password?
