Hello KDE lovers, having KMail with corporate EWS account set up I have some questions here:

- from time to time KMail gets "offline" so stopping to receive or show emails contents. Is there a way to turn it off and keep it online all the time or at least increase this timeout if exists?
- I have a filter rule that studies incoming emails for my surname's presence in To field and marks such letters with tag or sets it as action item i.e. paints it in some color. The matter is that while emails have unread status they just still displayed black and bold and to see filter's work result I should mark all messages as read first. Is it possible to see filter's result as soon as emails have been arrived and yet staying untouched in inbox so I can immediately see if it destined to me personally?
- is there any way to have EWS address book and calendar working in kmail?

Thanks beforehand.
