Signing not possible / Only outdated certificates are in selection

Hi,

I’m currently switching my solution to sign documents from 3rd Party Tools to “all-in-one” by LO. After reading the manuals, I configured my Thunderbird profile as certificate storage in the settings.

When I now try to perform a signing task (e.g., during PDF export), the dialogue for choosing the certificate only provides outdated certificates (1x oudated PGP, 1x outdated SMIME), but not the current one (1x new/current SMIME).

2 Years ago, I switched from PGP to SMIME. But I need all outdated certs in Thunderbird to decrypt old mails. Therefore deleting old certificate is not an option.

Thanks in advance for any hints!
