Hi 94880678,
Do you mean that when you wrote the address of network drive in wiki tab, the link has no access to the network drive location?
This feature does not support now.
We recommend you that please give a feedback to https://microsoftteams.uservoice.com/forums/555103-public/suggestions/18630043-allow-hyperlinking-to-network-drive-locations. Microsoft will always focus on customer’s feedback and experience. Some new features would be added to the services based on customers' feedback in the future, and your good ideas will be very helpful for them to improve the service.
Your time, understanding and cooperation will be highly appreciated.
