How to Temporarily Reset Cached Views
If you are having problems as a result of too many search folders, you can delete existing search folders by following this procedure. The effect of this modification is temporary. During the store's maintenance cycle, Exchange Server 2003 cleans up the existing search folders, and then resets this registry key to its default value. Exchange Server 2003 then resumes creating search folders normally.
This topic contains information about editing the registry.
Warning
Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data.
Start Registry Editor on the Exchange server.
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\< Server name>\Public-<GUID>\.
If Reset Views does not exist, add a new string value:
Value: Reset Views
Type: DWORD _
Data: 1
Where the data values represent the following:
0 = default behavior
1 = delete existing search folders during the next maintenance cycle.
The next time the Exchange store maintenance processes run (typically 02:00 or 2:00 A.M.), Exchange Server 2003 will delete the existing search folders, and then reset the registry key to 0.
