[Python] Fail to extract outlook mails of current week in shared folder using python [closed]

I tried to extract mails from a shared folder on outlook, which I have access to.

However, I am not able to get the mails for current week. For example, today is 12 Mar 2025, and only mail from 4 Mar 2025 and before are accessible to my python code.

Everything is normal when I applied the same code to my personal inbox folder instead.

How can I diagnose the reason and solution of the delay on shared folder? Thanks

Below is the python code I applied. It only prints out mails from one week ago...

import win32com.client

outlook = win32com.client.Dispatch("Outlook.Application")
namespace = outlook.GetNamespace("MAPI")
shared_folder = namespace.Folders["abc"]
subfolder = shared_folder.Folders["Inbox"]
items = subfolder.Items
items.Sort("[ReceivedTime]", True)

for i in range(50):
email = items.GetNext()
if email:
print(email.Subject)
else:
break
