Hi,
I'm using Thunderbird sending Mail.
When using Dolphin as File-manager, I can not share files by right-clicking and selecting "share by mail".
A small Messages appears for some milliseconds an nothing else happens.
It is also not possible to drag and drop files for sending them as an attachment.
Thunderbird is selected as Favorite-Application. There is no other Mail-Client installed.
Thank you in advance for your help.

Best regards,
Uli
