Open Two Different Instances Of Outlook With ExtraOutlook

Sure, normal people only need to be connected to one Exchange server or have open only one instance of Outlook. I guess that means I am not normal! I have several Exchange servers I use daily and sometimes I need to be connected to more than one in a clip - and until now this posed a huge problem. When you try to open a second instance of Outlook it would just open it within the current context.

In plain English it would open a duplicate inbox to the one I already had open. It was doing nothing for me when I need to multi-task.

I found this tool written by a hacker called TheHammerOfGod that does EXACTLY what I needed it to do and it was also FREE.

If you have a need to launch multiple Outlook windows and you ARE NOT using advanced plugin’s like Xobni than you should definately give this a shot. It is SUPER EASY to use and for those of us that wished we had this for years will find it VERY ADDICTIVE! Check out the download here and you can Visit the HOG website here.

extraoutlook.exe

I mean this couldn’t have been easier! I wish I would have found this a hell of a long time ago!

I downloaded the executable and ran it via Windows XP. I had my initial work installation of Outlook 2003 running and Windows shot back the above syntax screen.

So I dropped to a command prompt and changed directories into my ExtraOutlook.exe folder. and ran the following command to get my second instance of Outlook 2003 going:

open two outlooks

And sure enough It worked just as advertised. It does use double the memory and processor power so this would be a no go if you are running 512MB of ram. And Outlook 2007 uses even more resources than 2003 and 2003 uses more resources than 2000 so plan accordingly!

open two instances of outlook

Anyone else use something else to run double or triple profiles of Outlook?

    So outlook can use 200% of the CPU and 100% of the available RAM?

    @ Karl

    Nice app. A while ago Mark wrote about how to run multiple instances of the same program on Windows, I think it will work with Outlook as well.

    I get stuck at the command line.

    My ExtraOutlook.exe file is on my desktop, so I click/type: start run cmd

    Then I go to: C:\Documents and Settings\Jan\Desktop>
    at the prompt I type: >ExtraOutlook.exe “C:\Program Files\Microsoft OFFICE11\Outlook.exe” /profile “aNameILike”

    then I get an error
    ExtraOutlook.exe is not a valid Win32 application

    Hi Everyone,
    Very nice approach! Thank you.

    My Outlook is customized to hide to tray when minimized. Currently I use two instances of Outlook running, and both of them are minimized (i.e. hidden to tray). But there is only one Outlook icon in tray! When I try to restore it, only one instance restores. Can anybody advise how to restore the second instance?

    Thank you in advance

    I’m having the same problem as Alex. It would be great to have two Outlook icons in the system tray.

    Thanks in advance!

    Jurgen

    Howdy Guys and Thanks Karl. I have the account settings done.

    And have some questions, hope someone can help.

    NUMBER 1: Does the second session only works from command line interface? Cos right now to start the 2nd simultaneous session of outlook I need to start Run Cmd and enter the whole code c:Extraoutlook>…… and press enter and then it starts. Do I have to do this everytime to run outlook 2, 3, 4 sessions? if yes, then any easy way of doing it, or do I always have to Start Run Cmd and full command and enter to run more sessions? like a short cut to do this thing for me, so everytime I click on it this whole thing gets done automatically?

    Number 2: Actually I already figured out # 2. Personal profile also has it’s own saving place in outlook folder named outlook1.pst… so just a little help with above question will be appreciated.

    @RLes: you can make a batch file that does the trick for you. Here’s how:

    - create a new empty text (.txt) file
    - open the text file and type something like this: extraoutlook.exe “C:\Program Files\Microsoft Office\Office12\OUTLOOK.EXE” (change the path if your Outlook is located somewhere else on your computer)
    - save and close the text file
    - change the extension .txt to .bat (for example: start.txt becomes start.bat)
    - put the .bat file in the same folder as extraoutlook.exe
    - double-click the .bat file
    - tadaaaaaaaaa … extraoutlook is started and you don’t have to type a single word! :)

    If you want, you can make a shortcut (for example, on your desktop) to the .bat file!

    Enjoy!

    Regards,
    Jurgen

    Where’d you get version 1.3? The download link above and the one on the author’s page both give me v1.2.

    And whenever I add a command-line switch, like the /profile “blah”, it just pops up the Usage window and disappears. If I leave the cls off, Outlook pops up with no problems.

    @Coogan

    I left the /profile stuff out … I’ve set the option to let Outlook ask me which profile I want to open when starting Outlook …

    Hi all,

    was anybody able to work with this stuff with 2 accounts in Exchange 2003 in AD env?

    I logged as a domain user, I get my Outlook, and I want to use second Outlook to work as another AD user.
    The ExtraOutlook.exe just starts another Outlook copy but with the same AD/mail account.

    Did anybody solve this problem?

    Nikolai.

    yes, It even works with two different accounts.
    All you have to do is ,
    To set the profiles that needs to be opened.
    start-controlpanel-mail-show profiles-select “prompt for a profile to be used” and thats it you have both different accounts weth extra outlook.exe.

    Hurray, This is really a good one.

    Thanks for the guide on making the bat file. The trick worked wonderfully and very fast.

    But unfortunately, I seem to have got some settings mixed up, so when the extra outlook opened, it overtook my main outlook and i lost my work outlook.pst, luckily I had made a copy few days ago, so only lost some not very important emails.

    I did however used imap function of google and downloaded all my message from one of my account and played with this extra outlook function for a while, but until I am sure that it will not screw up my main copy of outlook I probably won’t pursue it further. it seems I have got some paths mixed up or perhaps put the files in the wrong directories. I remember that initially when I created the 2nd profile, I gave it same “pop email details” as my original and main work use one, which could have caused all this trouble. I know.. stupid of me…

    Anyway, will give it another shot some other time. Thanks for the treat tip and help.

    If anyone is interested, I created a small setup program for ExtraOutlook that extracts ExtraOutlook into your Outlook application directory, creates a script to execute ExtraOutlook, and creates shortcuts to the script on your Desktop, Start Menu or Quick Launch toolbar.

    It is available for download here: http://www.happycynic.com/download/ExtraOutlookSetup.zip

    Echoing what Coogan said, “Where’d you get version 1.3? The download link above and the one on the author’s page both give me v1.2.”

    It appears that the “profile” switch is not available in v1.2 and that function would be very useful to me. Other people have found ways around this, but it would be nice to be able to use the “profile” switch.
