How does Outlook handle special characters in URLs and what impact does this have on email links?
Outlook may not handle special characters in URLs properly, leading to broken email links. To ensure that URLs with special characters are correctly encoded and displayed in Outlook, you can use the PHP `urlencode()` function to encode the URL before including it in the email.
$url = 'https://example.com/page?param=value with spaces';
$encoded_url = urlencode($url);
// Include $encoded_url in the email as the link URL
