TMCM 7 supports IE11 and Edge Microsoft browsers. The issue occurs if the TMCM 7.0 server is a member of an Active Directory Domain but the user is using HTTPS://TMCM_HOSTNAME:<SSL_PORT> to access the management console.
To resolve this issue, access the TMCM 7.0 Web Management Console using a server FQDN such as HTTPS://TMCM_FQDN:<SSL_PORT>.
Alternately, disable the Internet Explorer Compatibility View.
