ACT and Outlook

I have set up 2 databases for different aspects of the companies work. I want to be able to use 1 email address for each user for both. I have tried rules in outlook with no success. The basic problem seems to be that the email address will only work with the default database, so if i have company 1 as default then any email addressed to me but for company 2 will not record.

(outlook rules used; Specific text in heading and body so if mail arrives and is addressed to me with Company 1 in the subject/body attach to ACT for company 1, if addressed to me with company 2 in subject/body then attach to Act for company2.)

Anyone help
