Outlook PST file still same size after all attachments deleted??

I am running Outlook 2007 and I will be migrating my PST file to an online email service I like (Zoho).  I wanted to reduce the size of the file because it is 16GB large.  I permanently deleted about 20% of my emails and then I ran Outlook Attachment Sniffer. OAS removed 6GB of attachments from my emails.  After all this I went to take a look at my PST file and it is the same size as before?? How is that possible?  How to I get the PST file to decrease in size?  It should be about 10GB in size now, not 16GB.

Try zipping the whole file and then check it's size again ,it might be that the size has actually shrinked but you do not see it for some reason.

To clean white space post deleting data you need to compact the PST using the instructions as per Microsoft Article below

How to compact PST and OST files to eliminate deleted item space in Outlook

Snippit from article:

Microsoft Office Outlook 2007

Delete any items that you do not want to keep, and then empty the Deleted Items folder.
On the Tools menu, click Account Settings.
In the list, select Microsoft Exchange Server, and then click Change.
Click More Settings.
On the Advanced tab, click Offline Folder File Settings.
Click Compact Now.

or you could create another data file (PST) and move all your emails to it.

Maclean, followed the directions in the article.  It took a little while and then it finished compacting the PST file and there is NO CHANGE in the size of the file.  I don't get it!  It should have worked but has not.

Zacharia, how do I create a new PST and move the emails into it?  Does anyone know id this would work?

Does anyone have any better ideas?

find the below link;

Once created a new one just drag/move the old emails to the newly created data folder.

It is always better to have separate PST files (data folders) and keep  emails arranged in smaller size.
You could use a 3rd party tool, if you are using the PST a lot.

Zach, I will try this soon and let you know.  All I am going to do is migrate the PST to my new account at Zoho, so I want to make the PST file as small as I can.  Since I deleted 20% of my emails, deleted 6gb of attachments and now compacted the PST, just to show no difference makes me nuts.
Is it possible that the file you are checking is just a backup and the file connected  to the account is some were else !?
Cause to be honest ,it sounds really weird that you make all those  changes yet the file remains the same size!

Do you have a recovery option when you right click on recycle bin? If yes, delete the mails in here too.

Ok, I created the new PST file.  Is there an easy way to drop and drag folders all at once or in groups ?  I can only D&D one at a time

If you disconnected the old PST, you can use import to import the settings from old to new PST.
If you are still utilizing the old PST, export the contents to a new PST, and once done connect the new PST (Probably ok to delete the newly created PST)
