需要在outlook中使用python切换帐户，以便使用其他帐户发送电子邮件

pip install pywin32

import win32com.client

def switch_account(account_name):
    outlook_app = win32com.client.Dispatch("Outlook.Application")
    namespace = outlook_app.GetNamespace("MAPI")
    accounts = namespace.Accounts

    for account in accounts:
        if account_name.lower() in account.DisplayName.lower():
            namespace.CurrentUser = account
            print(f"Switched to account: {account.DisplayName}")
            break
    else:
        print(f"Account '{account_name}' not found.")

# 切换到指定账户
switch_account("your_account_name")

# 在当前账户下发送邮件
outlook = win32com.client.Dispatch("Outlook.Application")
mail = outlook.CreateItem(0)
mail.Subject = "Test Email"
mail.Body = "This is a test email."
mail.To = "recipient@example.com"
mail.Send()
