Cannnot display folder error

Question

Cannot display folder error shows up when trying to add a new public calendar to my outlook desktop app. The mailboxes are on premise and only one user is having this issue.

@Manuel

Do you mean you want to open a calendar which contained in public folder? From the error message, we can know that this calendar isn't a mailbox calendar, so it cannot be opened in this way.

If so, I would suggest you follow steps below to open it rather than from "Open a Shared Calendar":

1. Click the Folders:
   
2. Find the calendar that you want to check, then double click to check it.
