Struggling with different phone number formats in email signatures? If your company’s user data in Entra ID is in chaos, our new feature will be great for you. You can now use regular expressions (regexes) to standardize contact info that shows up in your email signatures. See the video above to learn how to use this powerful new feature.
Why use regular expressions to format user details in signatures?
CodeTwo uses placeholders to automatically insert a sender’s contact details, such as their name or job title, and other information, into email signatures. By default, this data is pulled from Entra ID (Azure AD) into signatures as it is. So if the user data in Entra ID is messy, this will ruin your signatures as well.
This is where regular expressions come in. A regular expression is a pattern-matching language used to find, format or modify text by defining specific character patterns (strings). In other words, by using regular expressions, you can, for example, convert numbers like: +11234567890, 1234567890;ext:=1234, +1-123-456-7890 or (+1).123.456.7890 into a unified format like (123) 456-7890:
This conversion only takes place in your signature, meaning your data in Entra ID remains untouched.
New to regex? No worries!
We’ve prepared some ready-to-paste regex patterns that you can use right away. Here are some examples you might find useful:
- Convert any phone number format to standard US format: (123) 456-7890
- Remove the country code from a phone number
- Format or modify email addresses
