25 Essential Outlook 2016 Command-Line Switches Every Power User Needs

As a longtime Microsoft Outlook specialist with hands-on experience in enterprise IT environments, I've relied on command-line switches to streamline workflows, troubleshoot issues, and unlock hidden features. These 25 switches can transform your Outlook 2016 experience, saving time on routine tasks.

The command line might seem daunting at first, but it's a powerful ally for efficient Outlook management. Whether fixing glitches or accelerating daily operations, mastering these switches delivers real productivity gains.

Getting Started with Run Commands

The simplest way to use these switches is via the Run dialog—a quick, one-line command launcher. Windows veterans know the drill: press Windows Key + R or search for "Run" in the Start menu.

Enter outlook.exe [switch] in the Open field and hit Enter. For context on command tools, see Command Prompt vs. Windows PowerShell: What's the Difference?

Quickly Compose and Send Emails

These switches speed up email creation, perfect for automation. Start a new message:

outlook.exe /c ipm.note

Add a recipient:

outlook.exe /c ipm.note /m admin@989214.com

Attach a file (omit /c as /m implies email):

outlook.exe /m admin@989214.com /a "C:\Mis documentos\deathstarplans.pdf"

Create Other Outlook Items

Swap the item type after /c:

• /c ipm.contact - New contact.
• /c ipm.stickynote - New note.
• /c ipm.task - New task.
• /c ipm.appointment - New appointment.
• /c ipm.activity - New journal entry.
