PST migration: number of items "not eligible for archiving" different from items remained in PST file !!

[Zenworks2001]

Hi,
After locating, collecting and migrating some PST files, I observe that the number of items "not eligible for archiving" is different from items remained in PST file.

Number of folders processed: 82
Number of items archived to vault: 5046 of 5407
    - Number of items not eligible for archiving: 361
Number of items moved to mailbox:  0 of 0

PST Migration completed successfully

   01.04.2009 09:26:19 Migration of \\fileserver\...\Before May 2008.pst has been successful, but the PST file contains items that could not be migrated. The PST file has not been set read-only.
   01.04.2009 09:26:31 Completed migration of PST: \\fileserver\...\Before May 2008.pst

If I reopen the PST, I observe that number of items is 174 and not 361. These items are read receipt, delivery receipt, ...

Thank you in advance for your feedback,

Hi Are you sure that there are no appointments, contacts and such stuff in the PST File? Cheers Michel

I've used "Advanced Find" and looked for messages, notes, tasks, appointements and meetings.
I've found some more appointements but total is still not correct.
How can I precisely look for all items in this PST?
I need to understand and explain to what correspond these "hidden" items.
Many thanks for your feedback Michel

If you want to know precisely, then I'd suggest that you open a case with Symantec, they're probably the only ones who can tell for sure. Sorry... Cheers Michel
