Outlook file size stays large even after compacting.

Outlook 2010 - 32bit

Win 8.1 - all updates installed


Hi there, hoping someone can shed some light on this for me.


Even after compacting the outlook pst file, the file size still seems to be huge.

Here are the details:


I've archived all the all old emails into separate pst files.

Compacted the main pst file, which it did drop down in size.

However when I do a folder size within the main pst file it shows the following


Inbox  1,283,757 KB (all sub folders included in that total)

Sent     761,452 KB 

Junk         3,330 KB

No other folders have anything in them, ie Drafts, Deleted, Outbox, RSS Feed, Search Folder


Total   2,048,539 KB or about 2 GB


The file size is showing 5,091,209 KB

Down from over 12 GB before archiving and compacting


Anyone know what's going on here?


Thanks for any help !
