I have two email accounts (Exchange) configured in Outlook. For one I have a S/MIME certificate configured which always signs the mails I send from this account.
Problem now is that Outlook also attempts to sign the mails I send from the other account. Obviously I always get an error message
Invalid certificate: Outlook cannot sign or encrypt this message because there are no certifcates which can be used to send emails from this adress "abc@example.com"
So, is there any way to configure Outlook to sign only emails from one account by default? Someone had a solution for multiple accounts and multiple certificates here, but I dont have a certificate for the second account.
Thanks!
