Do we have an existing account for Bing Webmaster profiles? If so, would you mind sending me the credentials?

I am not sure what you mean by your question. 
Do you mean the Microsoft outlook accounts?


All the accounts we have on Bing are under the medstarmedia.com@outlook.com email.

Username - medstarmedia.com@outlook.com
Password - TeamXmed$tar@#1

Correct. I need the credentials to the account with access to our other Bing accounts.

Ok, these didn't work for me. I also tried: 

medstarmedia@outlook.com (no .com after medstarmedia)
TeamXmed$tar@#1

The .com version doesn't seem to be registered. The medstarmedia@outlook.com does but the password doesn't work. The recovery email message is: Email code to su*****@medstarmedia.com

I'm not sure who that is. Do we have another set of credentials?

I thought I set up the outlook.com email for support. It looks like I did not.
All of the bing accounts we have are under the support@medstarmedia.com email

Ok, I've taken ownership of the account, verified it, and updated the info. But, the address was old and needed to be updated, so Bing is sending a verification pin to their physical location. I've already spoken with the team and they'll email me the pin once it arrives.

The account is connected to support@medstarmedia.com

I'll mark this complete once I get the second verification pin.

Yes, that happens all the time when you update the info. 
Please remember to get an email from the client and add them as OWNERs as well. 
Thank you
