HideOutlookFolders is a specialized Windows utility software developed by ITSTH designed to declutter your Microsoft Outlook navigation pane by making unwanted, un-deletable default and user folders invisible. Key Capabilities and Features
Hides Core System Folders: Microsoft Outlook natively blocks you from deleting or hiding default folders. This software bypasses that restriction, allowing you to hide folders like Junk E-Mail, RSS Feeds, Suggested Contacts, Outbox, Drafts, Sent Items, and even the Inbox itself.
Preserves Data: Hidden folders still exist and continue to function normally in the background; they are simply masked from your visual side pane to save UI space.
Streamlines Multiple PST/OST Accounts: When managing multiple email accounts or data archives, Outlook automatically duplicates unnecessary system folders for each file. This tool cleans up the layout by letting you hide the redundant folders you never use.
Universal Account Visibility: The hidden status is modified directly as an internal property of the folder. This means if you hide a folder, it applies across all user profiles accessing that specific data configuration. Supported Versions and Limitations
Compatibility: It supports classic desktop versions of Microsoft Outlook, specifically Outlook 2003 through Outlook 2016 (both 32-bit and 64-bit architectures).
Folder Restrictions: While it can hide almost all standard user and default folders, it cannot hide Outlook “Search Folders”.
Environment Note: It is engineered for classic Windows desktop applications, meaning it does not natively apply to the web-based Outlook or the completely redesigned “New Outlook for Windows” framework. How to Get It
The tool is commercial software available directly from the developer on the ITSTH HideOutlookFolders Product Page.
If you are using a newer version of Outlook (like Microsoft 365) and want to clean up your pane without third-party software, you can alternatively use manual technical workarounds like the free MAPI property editor MFCMAPI or execute a custom VBA script to change the hidden attributes yourself.
If you want to move forward with cleaning up your layout, please let me know: Which version of Outlook you are currently running?
Are you dealing with a single email account or multiple shared mailboxes/PST archives?
