Sending, Receiving, and Notification Performance

In Outlook 2011, it could take a while to receive a message even if it were on an Exchange account. The reason is that Outlook was polling the server periodically for new messages.

Outlook 2016 does true push from the server, and as a result the time to notification of a received message, and the speed of meeting requests making their way through the process are significantly an issue. Together, these presented a feeling of a much more up to date, and snappy interface. Overall, we found Outlook 2016 to be about 5x faster in receiving messages than Outlook 2011.

Also, it isn’t just on the receiving side. Outlook 2016 sends emails a great deal faster as well — 15x faster.
