Hello, I am trying to write a function to determine if a list of email addresses are valid: Here is my problem:
The last check is if the lists (starting at B2, ends with a valid extension. .com,.net ETC. I have a list of all 1107 extensions in a different tab workbook.
Im guessing the length has to be involved somewhere, but am at a complete loss at where to start for this.
Any help would be greatly appreciated.
