When outlook is closed while some (old?) S/MIME mail is previewed, it triggers 2 save dialogs:

• This does not happen (so far) for new mails
• A new copy of the mail (in another folder) works fine
• Choosing to save the mail does not seem to change it

To reproduce:

1. Preview ted:INBOX/Sicherheitslevels:3 security level 3 (smime)
2. Close Outlook -> Save dialog is shown

Other mails, which trigger this (created 21.04.26, so not too old):

• ted:INBOX/Mailformate/10* - smime both (encrypted/signed)
• ted:INBOX/Mailformate/11* - smime encrypted (only)

Logs: (preview and close)
