How Does Outlook's Leave On Server Work For Pop Account RRS feed

  • Question

  • If I set leave on server to 10.  What removes it after 10 days.  Does the server do it or does running outlook do it?  That is does Outlook scan all mail on the server and delete messages older than 10 days?

    Also, where is the timestamp of the last message read kept so Outlook doesn't download messages it already has read?  Does Outlook include the timestamp of the last message read in the information it sends to the server when connecting to it?

    I need to do some testing using multiple Outlook profiles using the same userid.  The problem is the userid has leave on server set to 14 days.  I get upwards of 50 spam emails a day.  So when I use the test profile it will download the last 14 days worth of mail -- around 500 items.

    I am also working with an iPhone.  It does not have a leave on server option.  So when are messages that it reads deleted -- when they are read or when they are deleted from the phone/

  • Outlook deletes them. It keeps the list of message ids in a hidden message in your local Inbox folder and checks if there are new messages every time it hits the POP3 server.  New messages are downloaded, old messages are deleted. If "Leave on Server" checkbox is unchecked, the messages are deleted from the POP3 server immediately after they are downloaded.
