Why do you think this could be a network problem? From your message It seems other users in your company can access OWA with no problems...can you provide more details about your scenario:
- If you have a hybrid configuration for your corporate e-mail
- Differences between users that access OWA with no problems and users that cannot access it: OS version, browser used, etc

Also, After you take care of what Juan said to do, try this

1. Try from multiple browser/machines/ on/off network

2. Have them login to portal.office.com and click the "outlook" app button. See if they get the same results

Try to narrow down the issue
