All things Enterprise Vault Outlook Add-in related still continue to fascinate me. Including this rather odd bug, where you might see the following in a DTrace of W3WP - which by the way might be not on the top 3 things that you'd collect a trace of when doing client-driven PST migration.
This bug shows up as:
EV-L {RESULTSBUILDER.EN_US} CreateError text '<ERROR Type='Unknown Exception' Operation='Page_Load' Id='54' Message='The network path was not found. (Exception from HRESULT: 0x80070035)'/>'
And the reason? Well according to this technote:
http://www.symantec.com/docs/TECH210800
The reason is that you're not using a Microsoft DNS server. I guess that's a LOT of people/companies, but, then maybe not many people are driving PST migration through the Outlook Add-in. Have you ever seen this? If so let me know in the comments below.
