Incorrect registry value specified.
This Error event indicates that the registry value was set to zero and was therefore reset to the default value. This Error event only occurs if the registry value is set to zero. This registry setting only affects non-system user accounts. The most used values are objtMessage and objtFolder. Setting these to less than default values can minimize the effect caused by many users who run tools that crawl their mailboxes indexing or scanning items for virus infections.
To resolve this error, do one or more of the following:
Caution 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.
Locate the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem\MaxObjsPerMapiSession for the value listed in the error.
By default, these values use a hard-coded maximum value and have no registry setting. Query your internal documentation to determine why this registry value was configured and why the value was set to zero. The minimum valid value is one. If you set this registry value, you must use a value of more than zero and not more than the maximum. The maximum values for keys are:
- objtFolder = 500
- objtMessage = 250
- objtAttachment = 500
- objtFolderView = 500
- objtMessageView = 500
- objtAttachView = 500
- objtStream = 250
- objtACLView = 50
- objtRulesView = 50
- objtFXSrcStrm = 50
- objtFXDstStrm = 50
- objtCStream = 50
- objtFolder = 500
