Hi,

I have outlook 2003 sp2 and my PST is in new format "office outlook"
i.e. 2003 version. My PST size is ~121 MB. On archiving this PST, the
size of the archival PST file was found to be ~1.08 GB. Can someone
throw light on this issue? Is this a bug or I am not doing some
archival in correct way?

Also tried another pathway. I created a new PST through outlook (PST
version 2003) and then individually copied the folders / messages from
original PST to the new PST. Result was again same. The replica PST
also was of tune of 1.08 GB. Tried repeating the steps by creating
another PST (format version 1997-2002). But still the same problem.

I could only conculde that when Outlook session is operating, MS
Outlook 2003 uses different API set / PST file driver to write to the
desitnation PST. However during copy from one PST to another or during
archival, outlook is using some different API set / copy mechanism.
Please someone throw more light on this.

Thanks in advance for time and consideration.

Regards,
Mandar
