Hi
I am trying to set up S/MIME emails with a third party who have sent instructions on how this has to be carried out.
I have successfully installed a Client Certificate on my PC and I can see this in Outlook Options >Security Settings>
Signing Certificate : myname
Encryption Certificate: myname
I have received an email from them with an Exclamation Mark in a Golden Diamond on the email.
I open this up and get to the window Digital Signature is Invalid and in Message Security Properties all lines show RED exclamation mark.
I browse to View Certificate and Select to Explicitly Trust This Certificate and expect the three red Exclamation Marks to turn to GREEN ticks and window that previously said Invalid to change to Valid but this does not happen.
Initially it was thought there was something causing an issue as it passed through the firewall but on investigation this doesn't appear to be the case.
I have now been sent the Certificate in a ZIP file to try and install but this is in .ASC format and I think this may be the problem why it wont accept by clicking on Explicitly Trust This Certificate.
Can anyone assist with this issue so that I can get their certificate imported and working in Outlook 2016
Thanks
John
