Declared by publisher means the switches come straight from the winget manifest the publisher (or community maintainer) submitted to microsoft/winget-pkgs.
Default for {type} means the manifest doesn't specify silent switches, so the framework's standard switches are shown (e.g. /S for NSIS, /quiet /norestart for MSI).

Frequently asked questions

What is the silent install command for Coremail?

Coremail uses EXE (Inno Setup). After downloading the installer, run: cmclient_4.2.3-1614_amd64.exe /VERYSILENT /SUPPRESSMSGBOXES /NORESTART. The silent install switches are /VERYSILENT /SUPPRESSMSGBOXES /NORESTART.

How do I deploy Coremail via Intune or Configuration Manager?

Use winget for the cleanest path: winget install --id Coremail.CMClient --exact 4.2.3.1614 --silent --accept-package-agreements --accept-source-agreements. If winget isn't viable in your environment, package the publisher's installer directly using the silent switches above.
