Download the latest release: Analyze-SpaceDump.ps1
This script reports the space taken up by various tables based on a database space dump.
The space dump must be obtained while the database is dismounted, or on a suspended copy if the issue is happening there. To obtain the space dump, use the following syntax:
eseutil /ms /v > C:\spacedump.txt
Then, feed that file to this script as follows:
.\Analyze-SpaceDump.ps1 -File C:\spacedump.txt
This script will only work with Exchange 2013 and later space dumps.
