IMAP statistics versus POP and Exchange?
I'm desperately looking for some statistics on POP usage versus IMAP and Exchange-MAPI, especially in a professional context. I know IMAP is used to access mail from mobile devices with limited bandwidth, whereas POP is a good old standard and Exchange is more business oriented. Does anyone know the approximate usage percentage of each protocol?
Thanks!

IMAP and POP are versatile.
Exchange is only intended for the servers that are being exchanged. This means that you will need to purchase an exchange server and use Outlook to read your email.
IMAP stores all of your email on a server (so if you read it on your mobile, your computer will still show the message as read)
POP will download all of your mail to your computer and delete it from the server after a certain period of time (so you can check your email from multiple computers during this period)
As for the actual usage statistics, I'm not sure, but I really prefer IMAP as it allows me to check email from all 5 of my computers.

I don't think anyone is using Exchange-MAPI on the Internet, just inside the local and private network. MAPI uses dynamic RPC calls and is not designed to work over the Internet. I think you can use "MAPI over HTTP", but this is just a hack to use low-usage mobile devices, instead of a local application instead of OWA ...
According to statistics, you could, on the one hand, search for Exchange license numbers, as well as smartphones running Windows CE and evaluate them, and on the other hand, search for protocol traffic statistics for IMAP4 and POP3

hotmail in Outlook using the outlook connector uses mapi over http, so if you think this is just a hack, there is nothing to discuss.
I think Google allows MAPI for some of them calendar and messaging. So this is not just a hack to use over the Internet. Far away from him.
MAPI is a complete two-way collaboration system, involving not only email but also calendars, tasks, contacts, etc.
IMAP is for email only. If you just want to receive email, then IMAP is probably the way out, as it is open and most widely used. If you are not using Exchange. IMAP (perhaps intentionally) works like crap on Exchange when compared to MAPI. But, oddly enough, he does a great job with everything else.
