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 in explorer 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 !

So the real size in explorer is 5GB but you think it should only take 2GB?
How about restart your computer and try again?

Yes, that's correct, I would think that it should be roughly 2gb and I have rebooted.

I'm sure, if I rebuild the .pst file it will be that size. By that, I mean create a new .pst file and copy the folders to it. Would rather not do that, but if I have to then so be it.
