Journaling database full at disck

Hi Ahmed Bargawi

Thanks for reaching out to Microsoft Q&A forum support

Based on your description, I understand that you're encountering a critical disk space issue on your Exchange server, as reported by SCOM. Upon investigation, you discovered that the Journaling database is consuming the entire disk capacity, and you're seeking a safe method to clean it without risking data loss.

From my perspective view, to address this issue safely, PowerShell is considered a best practice approach due to its precision, auditability, and automation capabilities. It allows administrators to manage journaling rules, archive or purge content, and clean up logs without compromising mailbox integrity. Recommended steps include:

NOTE: Strictly avoid direct deletion of journaling database files or mailbox content to prevent data loss.

First of all, you need to use Get-JournalRule and Remove-JournalRule to identify and remove obsolete or redundant rules. This prevents unnecessary journaling and mailbox growth. Guidance on journaling procedures is available in Microsoft’s official documentation.

Next steps:

1. Ensure the Journaling mailbox size limit is set appropriately high or unlimited to accommodate large volumes temporarily. For more information, see LINK
2. Safely free up space using PowerShell scripts like CleanupLogs.ps1 or eseutil for log truncation. This is especially useful when disk space is critically low. See Truncate Exchange Logs with PowerShell or see Document
3. Periodically remove old Exchange log files and temporary files that do not relate to journaling to free disk space safely
4. Assign the Journaling mailbox to a dedicated database on a disk with sufficient capacity and monitor its usage to prevent overflow

Given the complexity and variability of server environments especially when dealing with critical data and configurations. As I am forum moderator, I am highly recommended to consult your Exchange server administrator. Every server setup is unique in terms of architecture, policies, and access levels, so having someone with direct access and tailored expertise is essential to ensure the safest and most effective solution.

Additionally, to help you reach your goal more effectively, I recommend posting a thread on the Microsoft Tech Community forum. It’s a great platform for deeper technical discussions and connecting with individuals who have hands-on experience and expertise.

Apologies for redirecting you to the related development team support as the moderators in this community have limited resources to check the backend information, and to get the fast and better assistance we requested for it. 

Best regards.
