The following error occurs when creating a folder in the S3-Compatible Object Storage bucket: "Unable to create folder (name: <folder_name>)".
Certain S3-compatible API do not support an unsigned payload used by Veeam Backup for Microsoft Office 365 as the x-amz-content-sha256 authorization header. Applicable to builds: 184.108.40.2065, 220.127.116.113.
Upgrade the Veeam Backup for Microsoft Office 365 server to version 4.0b (build 18.104.22.1686) or contact technical support to get a patch for version 4.0a (build 22.214.171.1243).
Veeam Backup and Replication and the S3-Browser tool (a 3rd party tool for S3 storage) are not affected.
