I have the following ideas that might help to address this:
- first check that the network connections are OK: open the Open/Join dialog, drop down the list, Run Network Diagnostics
- if the above does not indicate any problems, stop the BIM Server
- you can use the new menu bar/tray icon for that; stop both the Manager and the Server
- after the services are stopped delete the following file: /Applications/GRAPHISOFT/BIM Server 19/BIMcloud Server 19/Mailboxes/Mailboxes.db
- restart the services via the menu bar icon, open a Teamwork project and check the user list
Let us know the results,
