Outlook command line switches

CommandLineSwitchRunOutlook command line switches are straightforward, but can often be problematic because there are multiple solutions to resolve any issue. Each time the program begins, the operating system executes outlook.exe, the executable file attaches to the thread, and then the operating system runs the command to start Outlook.

The command to start Microsoft Outlook is usually Outlook.exe and by adding a sub command we can customize how Outlook starts. This is called a switch and it will enable the user to provide additional information in how they want to execute a command. The switch will present as a space after the main command, followed by a forward slash, and then the name of the switch.

For example:

Outlook.exe /nopreview

1. The command outlook.exe starts Outlook.

2. The switch /nopreview starts Outlook with the Reading Pane turned off.

  • Switches are not case-sensitive. For example, /NOPREVIEW functions the same as /nopreview.

  • Remember to include one blank space before the switch and one before each parameter.

Please find below a few standard switches that will help you resolve your Outlook issues through the installation of customized and automated parameters: 

Switch

Description

/a

Creates an item with the specified file as an attachment.

"c:\program files\microsoft office\office14\outlook.exe" /a "c:\my documents\labels.doc"

If no item type is specified, IPM.Note is assumed. Cannot be used with message classes that are not based on Outlook.

/altvbaotmfilename

Opens the VBA program specified in otmfilename, instead of %appdata%\microsoft\outlook\vbaproject.otm.

NOTE: This command line switch is only available if the following Windows registry DWORD value is set to 1. HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Security\EnableAltVba

/c messageclass

Creates a new item of the specified message class (Outlook forms or any other valid MAPI form).

Examples:

/c ipm.activity creates a Journal entry

/c ipm.appointment creates an appointment

/c ipm.contact creates a contact

/c ipm.note creates an e-mail message

/c ipm.stickynote creates a note

/c ipm.task creates a task

/checkclient

Prompts for the default manager of e-mail, news, and contacts.

/cleanautocompletecache

Removes all names and e-mail addresses from the Auto-Complete list.

/cleancategories

Deletes any custom category names that you created. Restores categories to their default names.

/cleanclientrules

Starts Outlook and deletes client-based rules.

/cleanconvongoingactions

Deletes the Conversations Actions Table (CAT). CAT entries for a conversation thread usually expire 30 days after no activity. The command-line switch clears all conversation tagging, ignore, and moving rules immediately stopping any additional actions.

/cleandmrecords

Deletes the logging records saved when a manager or a delegate declines a meeting.

/cleanfinders

Resets all Search Folders in the Microsoft Exchange mailbox for only the first profile opened.

/cleanfreebusy

Clears and regenerates free/busy information. This switch can be used only when you are able to connect to the server that runs Exchange.

/cleanfromaddresses

Removes all manually added From entries from the profile.

/cleanmailtipcache

Removes all MailTips from the cache.

/cleanreminders

Clears and regenerates reminders.

/cleanroamedprefs

All previous roamed preferences are deleted and copied again from the local settings on the computer where this switch is used. This includes the roaming settings for reminders, free/busy grid, working hours, calendar publishing, and RSS rules.

/cleanrules

Starts Outlook and deletes client-based and server-based rules.

/cleanserverrules

Starts Outlook and deletes server-based rules.

/cleansharing

Removes all RSS, Internet Calendar, and SharePoint subscriptions from Account Settings, but leaves all the previously downloaded content on your computer. This is useful if you cannot delete one of these subscriptions within Outlook 2010.

/cleansniff

Overrides the programmatic lockout that determines which of your computers (when you run Outlook at the same time) processes meeting items. The lockout process helps prevent duplicate reminder messages. This switch clears the lockout on the computer it is used. This enables Outlook to process meeting items.

/cleansubscriptions

Deletes the subscription messages and properties for subscription features.

/cleanviews

Restores default views. All custom views that you created are lost.

/launchtraininghelpassetid

Opens a Help window with the Help topic specified in asset id displayed.

/m emailname

Provides a way for the user to add an e-mail name to the item. Only works together with the /c command-line parameter.

/recycle

/remigratecategories

Starts Outlook and starts the following commands on the default mailbox:

Upgrades colored For Follow Up flags to Outlook 2010 color categories.

Upgrades calendar labels to Outlook 2010 color categories.

Adds all categories used on non-mail items into the Master Category List.

NOTE: This is the same command as Upgrade to Color Categories in each Outlook mailbox properties dialog box.

/resetfolders

Restores missing folders at the default delivery location.

/resetfoldernames

Resets default folder names (such as Inbox or Sent Items) to default names in the current Office user interface language.

For example, if you first connect to your mailbox in Outlook by using a Russian user interface, the Russian default folder names cannot be renamed. To change the default folder names to another language, such as Japanese or English, you can use this switch to reset the default folder names after you change the user interface language or install a different language version of Outlook.
