When I go to calendar in my outlook, I see multiple calendars. One of them is
on the server and second is on my laptop. By default all my mails are
downloaded to my laptop. This scheme worked well till the time I started
using my Nokia for synchronizing mails, contacts, calendars. My problem is as
follows:

(1) Since my mails are downloaded, on my laptop, when I accept a calendar
invite, it updates my local copy and not the server. As a result when data is
synchronized between my phone and server, calendar entries are not
synchronized. So I have two options (a) Synchronize my phone with laptop
using a cable, this is not a preferred solution (2) Manual copy calendar
entry from my laptop to my server calendar. These entries are automatically
copied on my phone.

(2) Same thing happens to my contacts

I would like a way so that my contacts and calendars are maintained on
server so that they get synchronized automatically without manual
intervention but mails should continue to download on my laptop. Is it
possible?
