You can deal with the corruption at mailbox level and can fix corrupt search folders, Provisional Fid, and Aggregate Counts. Also, it can be run against a single mailbox or against the entire EDB database.<\/p>\n<p><strong>Limitations of Exchange Management Shell cmdlets<\/strong><\/p>\n<p>Exchange limits the number of repair requests per server to maintain consistent performance. Only one request for database level repair is permitted at a time; in the case of mailbox-level repair, up to 100 requests for is permitted at a time. There is no option to perform repairing on all the databases of the server at a time.<\/p>\n<p><strong>Fixing the issues with public folders<\/strong><\/p>\n<p>Exchange Management Shell cmdlets can be used to fix issues with public folders as well. The syntax is:<\/p>\n<p>New-PublicFolderDatabaseRepairRequest -Database &lt;DatabaseIdParameter&gt; -CorruptionType &lt;PublicFolderDatabaseCorruptionType[]&gt; [-Confirm [&lt;SwitchParameter&gt;]] [-DetectOnly &lt;SwitchParameter&gt;] [-DomainController &lt;Fqdn&gt;] [-WhatIf [&lt;SwitchParameter&gt;]]<\/p>\n<p><strong>How to stop the repairing process?<\/strong><\/p>\n<p>Once the repairing process has begun, it can be stopped only by dismounting the database.<\/p>\n<p><strong>Dealing with the corruption in earlier versions of Exchange<\/strong><\/p>\n<p>If you are using an earlier version of Exchange, you will have to use Information Store Integrity Checker\u00a0(ISInteg)\u00a0tool to fix the corruption issues. However, we are not going through the details here.<\/p>\n<p><strong>EDB to PST Conversion \u2013 another way for easy EDB file recovery<\/strong><\/p>\n<p>When the EDB files of Exchange Database become corrupt and inaccessible, they can be converted to PST files so that they are accessible with MS Outlook.
