The vCard is sent as an attachment, it is not part of the signature.

How it's displayed will depend on the receiver's email application (or web interface, etc). See the attached image as an example.

When composing an email the vCard does not show up but it is still sent, in my tests I was able to use a signature at the same time so that's where you could put your disclaimer.

Hello Fabian,

Thank you for your time in answering my question.

Unfortunately, your recommendations do not seem to solve my problem.

Replicating your screenshotted settings, I am only able to send out the disclaimer text. The vCard is not being attached, as I performed various tests with other recipients.

I have tried all manners of combinations between the 3 'checkbox' settings within that Thunderbird screenshot you sent me, but every time I try to send something out it is either the Vcard OR the disclaimer text.

Do you have any other alternatives / suggestions?

Merci beaucoup.

I've just tried the same. I did this in Safe Mode as I do have some addons.

Results. When composing an email the vCard does not show up, but signature does. VCard does not even show as attachment. Enter email address and Subject Used 'Send Later' option.

checked the 'Outbox' folder in Local Folders. selected email, signature (with disclaimer) still visible and now the vcard is shown as an attachment, but the content of vcard is not visible.

'View ' > select 'Display Attachments inline' selected email, signature (with disclaimer) still visible and now the vcard is shown below the signature, exactly the same as example image.
