Outlook & Win98 Problem!

Hey yall!

I went to a client and install Outlook 2000!

It's on a Windows 98 OS!

I opened outlook and set everything!

So far so good!

I can receive message but i can't print nor send a new message!

It giuve this Error :

Out of Memory or Systems Ressources, Close ...

But there's no other program opened and there's 128 RAM

So what could be the problem!

Could it be a conflict between 98 & 2000 or
because i only installed Outlook of Office?????

Can some1 give me some info!

I did'nt search on MS yet, i will if no one can help!!

Thanks
