Reading Outlook Emails in Shared Folder - Python

Question

I have been using the below code to access a public folder in Outlook:

import win32com.client
import datetime


outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")

inbox = outlook.GetDefaultFolder(18).Folders.Item("xxxxx")
messages = inbox.Items
date = datetime.date.today()


subject = "xxxxxxx"

for message in messages:
    if subject in message.subject and date in message.senton.date():
     print(message.senton.time())

However, our Outlook has been moved from an Exchange server to the cloud and public folders have been changed to shared folders (I think?). The above code no longer works and I get the below error:

pywintypes.com_error: (-2147352567, 'Exception occurred.', (4096, 'Microsoft Outlook', 'The attempted operation failed.  An object could not be found.', None, 0, -2147221233), None)

Is there any way to search emails from a shared mailbox?

Thanks
