The Act! Outlook integration is designed to be used when a single Outlook profile is in use. It does not support switching between profiles, and is not recommended to be used in multi-profile environments. Though testing, there are some features that are expected to work in these cases, such as outbound email history recording, however contact and calendar sync would not update between active profiles.
If you would like to test this functionality in your own environment, I would suggest downloading and installing a Demo version of Act! and evaluating these particular features.
