I have tried adding my company mail adress as an user on google webmaster tool.
I know that company email needs to be associated with a gmail account.
In order to do that i have added my company mail adress firstname.lastname@example.org to my gmail account email@example.com as an alternate email adress following the steps here https://support.google.com/accounts/answer/176347?hl=en
However when i try to add my company mail adress firstname.lastname@example.org as new user on google webmaster tool it says
Can't associate email@example.com with any Google account
I think i have done all the required steps.
What could be wrong?
