v4.28.0 - 2026-05-18

Set-OutlookSignatures

Additions

• Add features to the INI editor .\sample code\IniEditor.html: Show template application order in addition to INI index number, touch support for the divider.
• Add a custom assembly resolver that helps avoid "DLL hell" across dependencies.
• Support extracting email addresses from New Outlook from its new UserSettings.json file format. This also adds support for "full account" mailboxes, and no longer requires the OneAuth lookup.

Changes

• Update libphonenumber-csharp to v9.0.30.
• Update MSAL.Net to v4.84.0.
• Refactor MoveCSSInline to no longer require a separate runspace.
• Reduce total package size by combining the new custom assembly resolver with a shared common DLL dependency folder.

Fixes

• Fix console color handling on Non-Windows systems.
• Show root cause error code and description in console output when the initializatino routine fails, instead of just the generic error 5 ("Common initialization routine failed.").

Outlook add-in (part of the Benefactor Circle add-on)

Changes

• Update @azure/msal-browser to v5.10.1.
