My Security Blocks access to my TeamViewer account

I have a corporate teamviewer 15 account. 

I was out of town visiting with family and did not have access to my Work email account. So I installed teamviewer on my Sisters PC, and attempted to login to my work PC.

I guess the security protocol is to send me an email to validate that I can trust the PC I am attempting to connect from. 

However, I was using Teamviewer in an attempt to login to my work PC to access my work email. That is to say, I could not add my sisters PC to the trusted list of computers because I did not have access to my work email or PC.

Is there a way to get around this?
