RSA Cert Error

[dricci]

My user is getting a Certificate Viewer Error.  Her Time is correct and I have it syncing to the Navy for for the heck of it. Nothing is is new that is blocked in local firewall. It is an odd email server that looks like it was from Rackspace mex09.emailsrvr.com.  I do not find it in her Local Certs to delete it.  It does not allow for a Trust anyway.  Can I have some suggestions.  

Thank you,

David

A fix maybe to delete the connection to O365 from within your portal of the user.  I will see how it goes.
