Frequently Asked Questions on How to Repair Corrupt Database Exchange 2016

How often should I perform maintenance on my Exchange database to prevent corruption?

Define a regular maintenance schedule and stick to it. Most veterans agree, on quarterly checks but this may be more frequent if your Exchange server has a history of corruption.

What’s the difference between soft and hard database corruption in Exchange Server?
Soft corruption is akin to logical corruption where the file structure collapses but the physical database remains intact. This failure affects mainly the metadata or is limited to only a few mailboxes in the Exchange server.
Hard or physical corruption is a critical situation where there is significant damage to the actual database files or storage unit of the server. In some cases, the damage can be so severe that it renders the entire database as unusable.

Is it possible to restore individual mailboxes without recovering the entire Exchange database?
The traditional methods only work on an all-or-nothing approach you won’t find the answers there. That’s why it’s better to rely on an automated solution that can give you the granular recovery options you require.

What are the signs that my Exchange database might be approaching corruption?
An Exchange Server rarely corrupts all of a sudden there are many early indicators. If action is taken on time then admin may be able to bypass the repairing entirely.
See if the Server is heating up more than usual.
Slowing down or freezing abruptly is also a symptom of upcoming corruption.
Reduce the workload or update the hardware so your Exchange server continues to function without failing.
