I have a computer which has Windows and Office installed on an 60 GiB SSD. Size of mailbox is around 13 GiB. The .pst file associated with the mailbox is around 31 GiB and I need to somehow make it smaller.
After setting autoarchive and trying to force archive using mailbox cleanup options, the archive.pst (on another drive) has now 13 GiB worth of mails, but I set only mails older than 12 months to be archived. It appears that all mails, even those outside the time range, were sent to archive.
Another thing I've noticed is that the archived mails are still in the main local mailbox. How do I move them so that they are only in the archive? Do I need to manually delete them from the main mailbox?
