Welcome to the RingCentral Community

Hey, I was able to log into sandbox environment using the new password. Thanks for your support, much appreciated

Our Team has reset the password on your sandbox account. You should have received an email on the password reset. Could you authorize using the new credentials please. 

Hello,

I've access to the mail account. I've checked both inbox and spam folder but the mail containing password was not there. I've also checked the main e-mail address but no luck with that too. Please take a look at the issue and thanks for your reply.

I have escalated this request for our support team to address.

In the meantime, have you checked with person who owns the main email address registered on the sandbox account to see if they've received this message instead of you (I've seen reports of this happening)? Also, have you checked your SPAM folders to see if the email has landed in there accidentally?
