Thanks for this translation.
There are a few things I would change. I hope it is OK if i write all this into this thread.
My proposals are colored green.
Code:
apptDetails = Appointment Details
apptDetails = Termindetails
Code:
asRead = Aie gelesen
asRead = Als gelesen
The correct word in german is "E-Mail". I would prefer to use the correct word, but it is just a suggestion.
Code:
calendarFolder = Kalender-Ordner
calendarFolder = Kalenderordner
Generally, such words should be written without a hypen.
I have to make a break here, I will continue if I have time again.
