Overview
When invitation files are processed, an email is sent with the results. If you did not receive it, there are other ways to get the information.
Information
The rejection file is always placed in the standard SFTP folder, which usually follows this naming pattern: /Incoming/[solution]/Invitations/Failure. Some customers may have rejection files stored in a different folder, though.
Please check the SFTP, either by looking directly at the rejection folder or by searching for the file you need using the search capability of the SFTP client. If you are unable to find the rejection file, please refer to this article: What to Do When the Import Rejection File is Missing on SFTP?
