I tried to change an user's active email in my sandbox(Sandbox name:stage) as they didn't want to get further notifications for the actions that we are doing in our environment

from : to :

It sends an email to the new user to verify the change. If I want to change it to an email like this, so that the user is not spammed with any notifications, what should I do?

Is there any way to suppress the email send to the new email address while making this change as a System administrator?

Normally a sandbox will update your users' email addresses by appending the suffix to it automatically on the refresh? Did it not do that? – Michael Welburn Feb 22 '13 at 19:11
@sathya I had encountered same and reached to sfdc and they had switched off for us by diabling some stuff – Mohith Shrivastava Feb 22 '13 at 19:19
to save anyone the trouble of looking, DMLoptions through apex can't stop these emails either. – Samuel De Rycke Feb 22 '13 at 19:48

Try this trick from for changing a user's email address (works in production too):

If you change the email address AND check the "Generate new password and notify user immediately" checkbox (all the way at the bottom of the edit screen) then the email address gets committed right away, no confirmation needed! Obviously the catch is that the user then gets sent a new password... so it's not any better in some situations.

Awesome man!! Thank you so much!!! :) – Sathya Feb 22 '13 at 21:36

When you create/refresh a sandbox, it should append the sandbox name to the end all of User Email addresses by default. I am assuming you changed it and now you need to change it back?

I don't have time to test it right now unfortunately, but maybe try using the Data Loader? That may bypass the restriction of accepting the email on the new account. I don't know exactly how they fire that validation off.
