SmarterMail Doesn't Run After Changing Windows Locale

This article applies to recent versions of SmarterMail. View articles for SmarterMail 16.x and earlier.

Modifying the server's Windows locale is not recommended nor supported as it can cause corrupted GRP files and prevent SmarterMail from running. This can happen when the changed locale causes the default CodePage to change. An example where this would occur is changing from an English locale to Japanese. Changing the default CodePage could cause corrupted files with unpredictable consequences. It is recommended to change the Windows locale back to the value it was set to on the initial SmarterMail install.

If the Windows locale must be changed, SmarterMail can be set to accept this change by doing the following steps:

  1. Open the Settings.json file with a text editor. The default install path for this file is C:\Program Files (x86)\SmarterTools\SmarterMail\Service\Settings\.
  2. Remove the following lines:
    "system_encoding": {
    "CodePage": 1252
  3. Restart the SmarterMail service.
Please note that any corruption or issues caused by the locale change cannot be supported by the Support Department.
