We use Google For Business for our work email.
We are trying to gain access to one of our old staff's email account, as he used his email address to register a piece of software that we use, and we now need to change it to our main service email, as we can't change our billing.
When we try reset the password, it sends a code to his phone, however he no longer uses the same phone number so he is unable to help us.
As Admin of the Google account, I thought I would be able to get around this, and access this inbox?
Any ideas would be much appreciated, thanks.
