Hello Frank

How are you opening your attachements?
Do you use the Link in the email header or go to the bottom of the email
and click on the attachment icon there?

When using the link in the header, those are meant for saving only.
Because of that, they shall not open those files directly.

Only when you use the icons at the bottom of the email, SOGo will open
them with the corresponding application set within your OS.

Kind regards,
Christian Mack
