Re: Yes, that's the reason to change the description to 'Datenspeicherung'.
That I did in the latest (1271) build.
Thanks.
I think the implementation has been quite successful
You mix up a bit active and passive voice. Mostly, passive is used.
I would use for explanation at 'Mail-Datenbank komprimieren' :
'Umfang des Datenspeichers optimieren, indem (übermäßig) alte Daten gelöscht werden.'
For the next topic I would recommend 'Löschen alter Daten aus dem Cache'. Cache is masculine.
Anyway, good work! Keep on going.
