Performance of MS-Exchange Server totally depends on the System Attendant service. Without it Exchange related services stop working. Like, Exchange server database cannot be mount, unless and until Exchange System Attendant service is not running. Information store of Microsoft Exchange also depends on Exchange System Attendant service. Data of Information store cannot be accessed. To get rid of problem related to information store and to access data of it, you can use a backup. If backup falls short to recover, then you can go for a third party Exchange server database recovery tool.
