Automatic compacting PST files

Posted on 2006-11-13
Last Modified: 2012-06-27
How can I automate compacting PST files?  Is there a way, for example, of compacting automatically on exit (as for emptying the deleted items folder)?  Alternatively, is it possible to add a toolbar button which compacts the default PST file (or all open PST files)?

Thanks for your help,

Hi pfsnet,

For Outlook 2002 and 2003 automatic compaction takes place as an idle task in the background. The following conditions must be true for this background task to take place:
• You must be running Outlook.
• Your computer must not be engaged in other CPU-intensive tasks such as copying or downloading files

To Patch or not to Patch? That is the question!

Sentinel0, was that the feature you were thinking of, or is there something else that will "compact once a day"?

Hi pfsnet,

Outlook already ccompacts pst automatically, just let it sit for a while. Is this not working?

We have some very big PST files that need to manually compacted.  The automatic compaction when idle function doesn't seem to work well enough.

Hey there pfsnet!

I think this tool is what you're looking for. They have PSTCompress and ExchangeCompress.

Since I'm not sure whether you're in an Exchange environment or not, I'll post links to both products:

* PSTCompress:
* ExchangeCompress:

They have an Enterprise and Personal edition of their PSTCompress product.

Hope That Helps!

Thanks to all for your help.

I have already seen the websites for the products mentioned (sentinel0's PSTCompactor and mike's PST Compress).  Are you recommending them from personal experience, or have you just found them by a web search?

Frankco's comment directly answers the first part of my question, so he also deserves credit.

I would have preferred a simple solution to force a PST compaction within Outlook/Windows, but it looks like that is not possible, so I'm just going to close the question and split the points.
