We suggest that you check with your colleague whether you were granted or had potentially revoked your access rights. If you have the necessary permission but still cannot see the document, we recommend verifying the level of confidentiality assigned to the document by your coworker as it is possible that you do not have permission to view content with a higher classification level. Alternatively, the document may be marked as containing personal data. In such case, you will be able to view the document once you provide a reason for accessing personal data (if required by your organization).
