MAPI Speed Performance
Question asked by Liam Dwyer - 2/25/2021 at 2:05 PM

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?

I noticed the same thing. Active Sync also outperforms MAPI in syncing a large email account.

The initial synchronization will take some time to complete as we're pulling down a 1:1 copy of the account, but subsequent updates should be very fast. If you're seeing delays after the initial sync I recommend submitting a ticket so we can take a look. As to EAS performance over MAPI, it is expected EAS will be a little quicker as its a mobile-focused sync protocol and isn't syncing nearly as much data down to the client.
