This setting can be found in the
Trados GroupShare 2020 Console and selecting the
Settings tab. From here, you will see the
Project Server Notification Settings menu.

The
Email Templates Location is the path where there email templates are found on a
Trados GroupShare server.
By default, the location is:
C:\ProgramData\SDL\SDLServer1\Templates.Browsing to the
C:\ProgramData\SDL\SDLServer1\Templates location
, you will see many template files, which are already configured for different project phases or tasks. The project template files can be configured to reflect the requested needs. Restart the Notification service via the
Trados GroupShare Console afterwards for the changes to be enabled.
Note: this customisation is NOT available in the Cloud version of Trados GroupShare.
