What is imap?

Imap is a standard mail protocol supported by all major email clients. In many ways it was a successor to POP mail.

POP mail worked by communicating to the mail server and downloading local copies of all requested mail. This was obviously bandwidth intensive, and made mail management ( especially folder management ) difficult.

IMAP is a protocol that allows remote management of a mailbox so that all email is stored on the server and can be manipulated remotely.

In the context of imap2Exchange, abeedoo does not store any email on our servers. We just act as a 'translation' service to convert the requests from the end-user (imap-client) to 'webdav' to speak to the exchange server.
