I have 1 Hotmail account and 2 Gmail accounts. For a long time now I have used my Hotmail address within the Gmail app to send and receive emails to and from Hotmail address. Now I have been told via email to said address that I can no longer use my Hotmail address to "send" emails only to "receive" emails. I have spent on and off the last 3 weeks on Google to try and find answers. I have been on Google's forum but I have not had any answers. And to be perfectly honest I want to close my hotmail.account. I sign into Microsoft to delete account and it requires verification. Trouble is my phone number that was initially set up I no longer have and cannot change it without that verification code. I have Microsoft Authenticator app and cannot use the codes that have been generated by them. I have registered my Gmail account with Microsoft with new phone number but am at a loss as to what I should do.
