What is the difference between POP, IMAP, or Exchange email configurations?

Depending on how you check your email, or depending on how many devices, you may find either POP, IMAP, or Exchange more advantageous. Below are the main differences.

POP POP downloads the messages to the particular device. The POP client has settings to allow you to delete the message from the server or leave it there so other devices can see it. Deleting the message from the POP client can be configured to remove the message from the server, but this will not affect any other POP clients. There is no true synchronization.

The advantages are:

* A local copy of your email.
*Uses very little server storage space as long as emails are downloaded and copies not being stored on the server
* Consolidation of many email accounts and servers to deliver to one inbox.

Disadvantages are:

* Potentionally no remote copy (if emails are deleted from the server as they are retrieved)
* No remote web access or synchronization between several programs or devices ie. smart phones, tablets, laptops etc.
* Local copies of messages still requires disk space to store messages.

IMAP Any change you make in any IMAP client will synchronize with the server, meaning any email read on your device will also automatically appear read when you check your account later via other devices, laptops, smart phones etc. Any messages or folders you read, move, or delete will be synchronized across all devices.

Advantages to IMAP:

* You can store and read your email locally, and have a copy stored on the mail server.
*Mail is synchronized throughout all IMAP accounts.

Disadvantages are:

* The number of messages you store is limited by your account’s server space, not your personal device(s). You will likely have more disk space locally, than the allotted server space

For people who intend to check their email from multiple locations or devices, IMAP is often the better choice, but care must be taken to stay within the storage space.

Exchange or Corporate

Exchange settings are not supported by all email clients. These settings will work as IMAP for your mail, but will also synchronize contacts and calendars to your devices.

Note: Each mail box that needs to sync calendars and contacts is required to be an Hmail Suite.  You can add Hmail Suites in your email manager and upgrade the account yourself, or contact support for assistance.
