Shared Computer Outlook E-mail Accounts

Question

I created a form with a custom e-mail submit button that sends the PDF form to the next approver that is selected by the user from a drop-down list. The form works correctly on computers that have only one Outlook e-mail account but the submit buttons do not work correctly when employess are sharing a computer (muliple Outlook e-mail accounts). Is there a way that when the Send By E-mail button is clicked, Outlook would, "ask" which account it should open?
Edit:
IT was able to help me with proper terminology that may elaborate this issue a bit.  Many users may share the same computer, under the same windows login username.  To facilitate them being able connect to their individual email accounts, we setup Email Profiles by going into Control Panel > Mail (in Windows).  We cannot select a default profile so we check the box for "prompt for profile to be used", which should come into play whenever the users opens Outlook or hits a "mailto" or "send to email" button from another application.  The user will see a "choose profile" window appear and they can proceed to enter their username/password upon selection of their Email profile.  Adobe seems to skip the "choose profile" window and will instead choose the first email profile we created on the machine, and ask for its username & password.  Although one might think we could just put in the correct username and password, that does not work since Adobe (or perhaps windows) is trying to authenticate the wrong email account.

Thanks-
Do you or does anyone else know of a way to use the MAPILogonEx function that is mentioned in the following Microsoft support page?  Perhaps it is hard-coded and not something that can be changed.

Particularly:
Use the MAPILogonEx function
When you call the MAPILogonEx function without specifying a profile and by setting the MAPI_LOGON_UI flag, MAPI displays the profile creation wizard if no profiles are on the computer. If profiles exist, MAPI displays the Choose Profile dialog box. Click New to start the profile creation wizard. (Since we have profiles created, it should display the choose profile dialog).

I'm wondering if our form/adobe is currently using MAPI_PASSWORD_UI which would choose a default profile
