You can find the SMC Corporate contacts through the Outlook app search function
Enter a name you are trying to find and wait a few seconds for the results to show up. It normally shows your local/personal contacts first.
If you don't see the person you are looking for, tap on the "Contacts >" option to see the full list of results:
When you select one you can chose many different functions including dialing their number (if stored in the system), adding the contact to your personal contacts (only do that if really necessary as those don't sync automatically if there are changes), etc.
