This will preserve your rules, custom views, and search folders as well as retain your folder structure. The better solution is using Archive to move old messages to a new pst file. When you re-download existing messages, the messages older than this date will be deleted.

The other option is to move the mail to another folder online (POP3 only downloads mail that is in the Inbox), or if your server supports it, configure the server to allow clients to download mail that is newer than a specific date (Gmail does).
This will avoid the need to download all 16K messages, it won't mess up the calendar or contacts, and you won't lose your views or rules. If you don't mind re-downloading everything, you can create a rule to move older mail to a different folder (or to deleted items) to delete it, but my recommendation is to archive the old mail to a new pst and keep the old pst for new mail. How can I avoid downloading all of the messages again?īecause the Mailbox Manager file that Outlook uses to identify the last message downloaded is stored in the pst file, you can't do this easily. I’ve been doing it this way for years, so I have some 16,000 messages stored on the server. I created a new pst in Outlook for 2015, making the 2014 PST an archive of sorts. It’s a new year and many people like to start off with a clean mailbox.
