I discovered that when I remove the data file &quot;Archive.pst&quot; from my Outlook account, NO Event ID 27 entries appear in the Application log.<br />

When I add the data file &quot;Archive.pst&quot; back to my Outlook account, then Event ID 27 entries start accumulating again.<br />

I did a SCANPST of my archive file. &nbsp;It contained errors, but the scan repaired them all. &nbsp;When I opened Outlook the Event ID 27 entries appear again in the Application log.<br />
