New release v4.23.0

Formatting address and phone number made easy

2025-10-18

🔗Goodbye formatting headaches with addresses and phone numbers, hello global standards

Set-OutlookSignatures v4.23.0 is here, delivering a major upgrade focused on two common - and surprisingly complex - pain points in global IT: Perfectly formatting phone numbers and postal addresses.

This release integrates world-class open-source libraries to ensure your organization's contact information is globally correct and consistently professional in every signature.

🔗Perfect phone numbers, effortlessly

We think phone numbers are easy because we assume they are just numbers and forget about global complexity. If you still think so, reading the article 'Falsehoods Programmers Believe About Phone Numbers' will change your mind.

We've added a new phone number formatter based on Google's libphonenumber library.

This feature converts raw numbers (and an optional country code) into standardized formats:

  • Human-readable INTERNATIONAL or NATIONAL formats.
  • Technical RFC3966 format for reliable tel: links.
  • A custom formatting option.

New replacement variables, such as $CurrentUserTelephone-International$ and $CurrentMailboxManagerMobile-RFC3966$, are now available.

For implementation details, see our Format Phone Numbers FAQ.

🔗Accurate postal addresses for any country

Just like phone numbers, postal addresses seem like child's play - if you're only working nationally. However, "Different countries, different customs". Read the article 'Falsehoods programmers believe about addresses' to understand the global chaos we've tamed.

A new Address Formatter module, based on OpenCage GmbH's work, ensures addresses are assembled according to country-specific rules.

Input named address components (over 20 available) and the country code to output the correctly formatted string via the new $Current[User|UserManager|Mailbox|MailboxManager]PostalAddress$ variables. A necessity for multinational companies.

For implementation details, see our Format Postal Addresses FAQ.

🔗Other key enhancements

  • QR Code Update: The sample QR code format has changed from MeCard to the more common vCard format.
  • Security: Added a check for PowerShell Full Language Mode to all administrative scripts.
  • Fix: Corrected an issue with culture-aware sorting in the Intune remediation sample script.

For a comprehensive list of all changes, dependencies, and fixes, please consult the official CHANGELOG.
