You can mount the Exchange database (EDB) on the server using Exchange Admin Center (EAC) or Exchange Management Shell (EMS). However, if the log files are missing or corrupt, you will be unable to mount the database on the server and receive an error, such as &ldquo;MapiExceptionCallFailed: Unable to mount database&rdquo;.

This tool can scan and restore data from corrupt Exchange database (EDB) file and save the data in PST and various other file formats, like MSG, EML, etc. It can also directly export the data from repaired EDB file to a live Exchange Server database or Office 365 with complete integrity. The tool supports Exchange Server 2019, 2016, 2013, and earlier versions. The software is an effective way to restore a database that fails to mount without the risk of data loss. It does not require log files to perform the repair and restore process.<\/p><p>To recover the database with Stellar Repair for Exchange, follow this instructional guide on <a href=\"https:\/\/www.stellarinfo.com\/support\/kb\/index.php\/article\/how-to-recover-corrupt-inaccessible-exchange-mailboxes\">How to Recover the Corrupt\/Inaccessible Exchange Mailboxes<\/a>.&nbsp;<\/p><h3 class=\"wp-block-heading\"><strong>Step 5: Mount the Database on the Server<\/strong><\/h3><p>Once the database is in <strong>Clean Shutdown<\/strong> state, you can mount it on the server using the following command:<\/p><pre class=\"wp-block-code command_container\"><code><strong>Mount-Database &ndash;Identity &lt;dbname&gt; &ndash;Confirm:$False<\/strong><\/code><\/pre><p>Alternatively, you can use the Exchange Admin Center (<strong>EAC)<\/strong> to mount the database on the server.<\/p><figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"268\" height=\"82\" src=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2020\/08\/Picture4-1.png\" alt=\"Mount the Database on the Server\" class=\"wp-image-177363 apply-gradient-on-post-images\" srcset=\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2020\/08\/Picture4-1.png 268w, https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2020\/08\/Picture4-1-150x46.png 150w\" sizes=\"auto, (max-width: 268px) 100vw, 268px\" \/><\/figure><p>The database will mount on the server without the <em>MapiExceptionCallFailed: Unable to mount database.
