How can I get lower-case email addresses through an address policy?

Question

We use %g.%s@contoso.com as our template in an email address policy.

This results in my email address Oliver.Salzburg@contoso.com, but I want oliver.salzburg@contoso.com. How do I get the address in lower case?

Answer 1

You need to use the replace instruction to replace every single upper-case letter with the lower-case counterpart: %rAa%rBb%rCc%rDd%rEe%rFf%rGg%rHh%rIi%rJj%rKk%rLl%rMm%rNn%rOo%rPp%rQq%rRr%rSs%rTt%rUu%rVv%rWw%rXx%rYy%rZz%g.%s@contoso.com

Please note that, if you have already applied the previous policy pattern, the lower-case addresses will not replace the previous addresses. You will have to remove those and re-apply the policy.
