So, my customer has an O365 Business account for one business and a GoDaddy O365 account for another business.
After setting up the GoDaddy account, he can no longer log into the MS portal as it automatically redirects to the GoDaddy portal now.
The redirect appears to be server side, but it might be checking a local cookie as you can sign into both accounts from two different browsers. But that's inconvenient for the user whose used to only using his default browser.
Is there a way to check the email on both accounts from the same browser?
