Hi,

We have several machines in our organisation where people have installed Extraoutlook, to open more than one instance of Outlook, which is kind of a security breach.

Now we need to remove this from those user machines but not able to find any significant entry in ARP or registry through which we can remove.

Does anyone have any idea on how we can remove this without hampering the normal outlook operations.

Thanks in advance.

Is it a legacy or MSI setup?
For the latter try to uninstall using msiexec /x {ProductCode} and see if that works.

For legacy and if you don't find any uninstall command then you would need to create a uninstaller that would remove the files/registry associated with extra outlook.

I've never heard of this one; how is it launched (exe, shell command...)?

The website for the product is blocked from my work, so I can't have a look at the installer.

From what I've read it modifies/replaces the Outlook executable so that you can run multiple copies of Outlook with differrent profiles without Outlook realising that it's already open.

You need to obtain a copy of the installer and snapshot the installation to see what it does and what it changes, then see if you can work out an uninstall from there.

Hope this helps,

Its a legacy, but the problem is it is nether making entry in the ARP nor in registry so that i can remove, nor can I find any entry that it is making into the system.

People are using a batch file to excute it, the command is as follows:

ExtraOutlook.exe "C:\Program Files\Microsoft Office\Office12\Outlook.exe" /profile <Profile Name>

I guess it would be hard to stop this if your users has local admin rights.
How about using something like GPO Software Restriction to prevent the file from being executed?

The best way would be to talk to the management to create a policy that prevents anyone from using this tool or any other unwanted software.
Then make the users sign the agreement.
If they do not follow the "security policy" then it's the management's responsibility to make sure they do follow this.

I am the author of ExtraOutlook and can tell you that it does not write to the filesystem nor make any changes to the registry. It is a stand-alone executable that only makes in-memory changes for the lifetime of the given Outlook process. Furthermore, it does not require administrative privileges to run.
To "uninstall" ExtraOutlook, you can just delete ExtraOutlook.exe.

Hi bubble_buzz21

How is "openning more than one instance of Outlook" , a kind of security breach ?

When the 2 instances being opened are for connecting to legitimate exchange servers and not to free/ personal email accounts like Hotmail.

As a software services provider, my organization uses a Ms-Exchange server.
My client's organization, I am currently working for, also uses a Ms-Exchange server.

I need 2 instances of outlook client running,
as I need a communication channel with client using the clients exchange server and
a communication channel with the rest of my organization, using our own organization exchange server.

(outlook web access is clumsy and does not provide a rich content editor, as does ms-outlook-client, is the primary driver)

thx
