Nokia and Microsoft Exchange Server
One of the functionalities that I really enjoy is the ability to set peak and off-peak mode on my e-90 in terms of exchange server. This means that I can create the down-time that we all need while at the same time allowing business activity continue during peak time.
I have set up my phone to sync, via exchange server, every 15 minutes during office hours and then from 7pm to 7am each day it does not sync. Over the week-ends it also only sync’s once every 12 hours.
Clearly some very thoughtful people put this together!
Ps. to all of those worried about battery life, I achieve three full days under this setup with in excess of 1 and a half hours of talk time per day.
