问题
After several days and multiple attempts I didn't find any 100% solution for this trouble. My search and investigation scopes:
- Direct access to registry: HKLM\SOFTWARE\Microsoft\Windows Search\CrawlScopeManager\Windows\SystemIndex\WorkingSetRules HKCU\Software\Microsoft\Windows Search\Gather\Windows\SystemIndex\Protocols\Mapi HKLM\SOFTWARE\Microsoft\Windows Search\Gather\Windows\SystemIndex\Sites\ and other keys...
- Windows Search 3.X interfaces like ISearchManager using Microsoft.Search.Interop
- Microsoft.Office.Interop.Outlook classes: NameSpace, Store
- AD policies (useless, no effect :(
Preferred technologies: VB.NET, C#. This solution must be deployed within a large organization (about 5000 wokstations).
Any ideas? Thanks in advance.
