Build an Email Address
This calculated column uses a SharePoint formula to build a standardized lowercase email address from a first and last name. Because it lives in a calculated column, SharePoint fills the value in for every item automatically - no custom development and nothing for your users to type.
How It Works
- What it does: Builds a standard lowercase email from the First Name and Last Name.
- What you get: An address – Jane Smith shows jane.smith@company.com.
- If a value is missing: If First Name or Last Name is blank, you get a partial address (like .smith@company.com) rather than an error.
Common Use Cases
- Generate standard company emails
- Pre-fill contact records
- Bulk account or mailbox setup lists
- Consistent address formatting

What does this formula do?
Generate a standard email. It lives in a calculated column, so SharePoint fills the value in automatically for every item.
Which columns do I need to set this up?
You need: First Name (Single line of text), Last Name (Single line of text). The formula reads these to produce its result.
Can I change the formula for my own columns?
Yes. Swap the column names in brackets for your own, and adjust any numbers or text.
If LookBook 365 is code-free and out-of-the-box, why does this example use a formula?
A SharePoint formula is native, declarative configuration, not custom development. It only works with the item’s own fields and simple logic – it cannot run scripts, reach external services, or change other data, and nothing is deployed to your tenant. It keeps working through Microsoft updates. If you would rather not set this up yourself, this is exactly the kind of thing I configure for clients.
