Just a question for the community. What type of speed are you seeing for MAPI with Outlook and Smartermail?
I am migrating some users from IMAP to MAPI with mailboxes ranging from 5GB to 25GB. I find the initial synchronization can take a considerable amount of time. I have also tried it local to the Smartermail server (on the same LAN) and it barely utilizes the network bandwidth at all.
Is this normal for MAPI protocol?
