Hello,

If you are talking about IMAP then, let me tell you the exact difference between POP and IMAP mail servers.

Well, POP downloads all your email messages from the email server to your computer and store on the hard drive. Most programs have the option to keep the messages on the server for x number of days but sooner or later the messages are removed from the server. Also, with POP your outgoing emails are kept locally on your hard drive which leads to the familiar and annoying situation where you have different emails on each computer that you use to check email: home, office, work, etc.

Where IMAP keeps all email messages on the server and never removes. In most cases your email application creates a local cache of messages on your hard drive to speed up the opening of emails, but the originals are not touched. Also, with IMAP (this is the big one!) your sent mail and drafts are uploaded to the server! Because of this, you will see the same incoming and sent messages from any computer as long as your mail program is configured for IMAP. POP3 does not have this functionality.

Since IMAP is an internet standard and the emails are stored on the server it's easy to switch between email programs and operating systems.

So, you can choose convenient option for you. If you can forward us the exact outlook error you are getting then we will suggest you the solution.
