Can I open more than one instance of Outlook at a time?

Home » Microsoft Office » Microsoft Outlook

Summary: Outlook is designed to be a single-instance application. There's an unwieldy trick to get more than one that may, or may not, be useful.

I need to open more then one instance of Outlook at the same time with a different profile on each instance. Can this be done?

Yes and no. But most probably no.

Outlook is a single instance application so for any user session you can have one - and only one- instance of outlook running.

There is a 'trick' you can play. Windows XP will allow you to stay logged in as one user while logging in as another. Select Logoff and then Switch User. The first account remains logged in while the second account logs in as well. Each of these users can have their own copy of Outlook running. The caveat of course is that they must be different user accounts on the machine.

I don't believe you can. You must restart Outlook to change profiles.

I am running a program called "True Launch Bar".
It has a plug-in called "Mail Monitor".
If you set mail monitor to use Outlook as your mail reader, it will lauch a new and simultaneous instance of outlook without loging off and on. Appaently as many as you want. Is there a way to keep outlook from launching more than once? Perhaps in the registry?

If someone has sent you a meeting request that you have not answered, you can click the "calendar" button (right side of upper bar) and that will open a second window that has full functionality. This second window will usually reopen if you allow Windows to close Outlook on shutdown and it is able to do so successfully.

You can also right click on Mail, Calendar, Contacts, etc (bottom right side) and select "open in new window"

I made a copy of outlook.exe (OL 2000) named outlook2.exe. But outlook2.exe would use the same profile as the aleady started outlook.exe even with the /profile parameter.

It is possible to get two accounts running using the ExtraOutlook program found here: http://www.hammerofgod.com/download.html It includes the story of how they found a way to get two separate instances running with different profiles.
