The user stf is experiencing an error when trying to add a backup email address to their profile, with the message “The address is already in use by a staged user.” This is likely due to a staged user account being created automatically by the system for email integration, as explained by Moin. To resolve the issue, stf may need to register with the second email address before the two accounts can be merged. JammyDodger is assisting stf to figure out the issue via a private message.
When trying to add an additional email address to my profile, I am getting this error:
There was an error changing your email address. The address is already in use by a staged user.
So perhaps I made a mistake and signed up twice?.. But password reset with the other address doesn’t work:
Password Reset
No account matches ***
where *** stands for my email address.
What am I doing wrong? How do I recover the old account? How many accounts do I have and why?
Thank you!
Looking at the information about staged users, I think everything works as designed. But maybe no one thought about the case where the email address will be used as a second one.
Staged users are created when you send an email which becomes a message in the discourse forum. For example, sending an email to team@discourse.org will automatically be converted to a personal message to the @team.
I’m not sure if you have to register with the second email address before the two accounts can be merged. But someone else will be able to help you.
Hello and welcome @stf 
I’ll send you a PM to get some more details so we can figure out what’s going on.
