Just saw the post Slaves to email on excess email in MS and I couldn't agree more.....

Large email volume for people who manage others, or those who interact with external customers is expected. But even for individual contributors (Dev/Test) the volume is just too high. We should really use the internal communicator more and get rid of those one-liner emails.

Since we work in a different time zone within a team distributed between Redmond/NorthCarolina/India we face a different issue. Each morning you enter office and you are welcomed with 100s of emails which were sent to you in the local night time. By the time you wade through them almost an hour is over. Mondays are worse as you have to wade through the all the emails sent during Friday in US.
