I have 2 mail profiles - one profile has a single Exchange 2010 account and the other has a single IMAP account. I want to open an instance of Outlook for each.

I execute outlook.exe /profile MyExchangeProfile for the Exchange profile and outlook.exe /profile MyIMAPProfile for the IMAP profile and the result is that I get 2 instances of Outlook each with the MyExchangeProfile.

In fact, whichever profile I load first is always the one that gets loaded no matter what profile I specify on separate executions.

Not worked for me with Outlook 2010 / Win7 Pro. Outlook open with the last profile you passed in argument /profile "myprofile". First time you run extraoutlook it open outlook with the profile you asked, and the second time, the first outlook profile instance change automaticaly to the second. Worked with earlier office version. Another idea? – Christophe Trevisani Chavey May 2 '11 at 17:36

Should this work with Outlook 2010 and Windows 7? I'm getting error: `Function not found in Import Table.' which to me implies a DLL might is missing, but the .exe was was the only file in the download. – Matt Oct 13 '10 at 22:13
Duplicate of answer here - uses the same tool but with more info. – HaydnWVN Nov 30 '12 at 16:22

I highly recommend you not to do so. Running several Outlook instances is unsupported scenario that leads to corrupted profiles and storages (believe me I saw I lot of these kind of situations).

Instead, add your IMAP account as a second account to your Exchange profile.

Hi Thims, I tried' suggestion of ExtraOutlook and have been using it successfully ever since. It works great with my two Exchange profiles. My email is continually backed up so I feel safe as well if there's a problem. What is the technical reason for the corrupted profiles and storage? – Matt Mar 8 '12 at 14:58
