Investigating Outlook's Single-Instance Restriction (PART 1)

The first thing I would have done was to check for mutexes with process explorer but it would have failed in this case even tho you are supposed to use a mutex and not just FindWindow, with no outlook instances running, starting outlook in a loop in a batch file or something should allow you to start a couple of instances (I have gotten multiple taskmgr instances a couple of times when the machine is acting slow)

So, to get multiple instances of outlook, i guess you could make a loader that renames all outlook windows and spawns a new instance, then reset the names

For multi instances I know of a few ways.

FindWindow
EnumProcess
Mutex
Something desktop specific
tmp file
shared memory?

Josh:
FindWindow: Is broken if you don't use a mutex

EnumProcess: What if some other app has the same name, or are you gonna check loaded modules or something?

Something desktop specific: Like?

tmp file: What if app crashes, no you wont start at all (DELETE_ON_CLOSE will help a little)

shared memory: I have not played with Vista that much, but I think UAC could cause problems, you don't have access to Global\xyz in the namespace

You can use "runas" to initiate multiple instances under other users but it reacts very strange (it runs under different users but displays the same inbox)
