I want to have logic that checks for the email domain and assigns value to connected field.

We have 4 companies on office365 same tenant.

I have a label that displays the users email address.

Based on the email domain (potentially 4 of them), I want to add the company name to a connected company field.

Example:

User Email = fred@acme.com

I want to say if the domain = company1.com then company field to have the value ACME.

Thank you for the help in advanced.
