  1. Ensure no backup jobs are running
  2. Stop Veeam Backup for Microsoft Office 365 Service

  4. Navigate to C:\ProgramData\Veeam\Backup365
  5. To change encoding for test emails, edit Config.xml file by adding the following line between <Veeam> and <Arсhiver>:
    <Email MessageHeadersEncoding="UTF-8" MessageSubjectEncoding="UTF-8" MessageBodyEncoding="UTF-8" />
    
    config.xml
  6. To change encoding for email notifications sent by a backup job, edit Proxy.xml file by adding the same line there:
    proxy.xml
