Impossible to sign emails with an eID card using Outlook 365 Enterprise

Question

Hello,

I cannot sign my emails using an eID (smart card) containing a signing certificate and an authentication certificate using Outlook 365 Enterprise. I have followed all instructions found in forums or Microsoft pages saying to configure it through the TRUST CENTER and I obtain always the same error saying that there is no certificates associated with the email account used. Since I am trying to use an eID (Electronic ID) it is never associated to a specific email address. Note that I am using an email server type IMAP/SMTP and that in the TRUST CENTER there is no button "Publish to BAL".

I have configured for another email box (Outlook server) the certificate coming from my company which is associated with my company email address and I published it to BAL since there was the button. There I can sign document with it now.

Note that with my eID card on the same computer I can sign PDF documents using Acrobat Reader and WORD documents using WORD 365 and online. The behaviour is correct in the sense that when asked to sign the document the computer asks to introduce the eID card in the reader to select and then asks the eID PIN code.

How can I solve this problem?

Regards.

Answer 1

Hi,

None of these steps are solving the problem:

1. the eID card and its certificate is valid and I can sign PDF and Word documents
2. Outlook is already the latest version
3. These options are already disabled
4. Creating a new profile is ending with the same issue

Hi @Pascal_033 ，

I’m sorry to hear that you’re having trouble signing your emails with a certificate in Outlook 365 Enterprise. Here are a few steps you could try:

1. Check the Certificate Validity: Open the control panel, navigate to Network and Internet > Internet Options. In the Internet Properties Window, select the “Content” tab > Click on “Certificates” button. In the Certificate window, select the “Personal” tab > Select the certificate you applied for and issued to your current account. Please check its valid time and make sure the address it issued to fully matches your current account address.
2. Update Outlook: Some client issues can be fixed by updating the Outlook desktop client, you may try to update it via File >Office account >Update Options >Update Now.
3. Check Email Security Settings: Go to File > Options > Trust Center > Trust Center Settings > Email Security and ensure that the “Encrypt contents and attachments for outgoing messages” and “Add digital signatures to outgoing messages” is unchecked.
4. Create a new profile: If the issue persists, you might want to try creating a new profile. In Control Panel > Mail > Show Profiles > Add, then re-connect your account.
