Challenge
Email notifications sent by Veeam Backup for Microsoft 365 unexpectedly contain Chinese characters.
Cause
The issue is caused by an encoding conflict. By default, Veeam Backup for Microsoft 365 uses UTF-16 character encoding, and the problem appears under the following circumstances:

Solution
Email notification encoding can be changed in Veeam Backup for Microsoft 365. Test emails are sent by the Veeam Backup for Microsoft 365 Service; job notifications are sent by the Veeam Backup for Microsoft 365 Proxy Service.
