outlook信件有迴紋針，但信裡看不到附件

 偶爾都會有使用者反應，收到的信件，旁邊有迴紋針，表示信中有附件，但信打開，裡面卻只有內文，沒有任何附件。

後來仔細的查詢，當信件進來後，經過第一層的圾垃郵件過濾系統，信還是完整的，附件也都有。

之後進到Mail Server，信也是正常的，然後Outlook收信時，從Mail Server的log上看到，的確也是整封信傳過去，所以就判斷問題是在本機端產生，不是Mail Server的問題。

防毒軟體在安裝時，有另外在Outlook內插入一個增益集程式，做附件掃描的功能，後來在Outlook裡把這個功能關閉，有問題的信在重寄一次，附件就出現了。

Occasionally, users have reported receiving emails with paper clips indicating the presence of attachments, but upon opening the emails, they find only the body text and no attachments.

Upon further investigation, it was found that when the emails arrive, they pass through the initial spam filtering system intact, with all attachments included.

Subsequently, when the emails reach the Mail Server, they are still in their original state. However, while receiving the emails in Outlook, it was observed from the Mail Server logs that the complete emails were indeed being transmitted. This led to the conclusion that the issue originated on the local machine and was not a problem with the Mail Server.

During the installation of the antivirus software, an add-in was inserted into Outlook to enable attachment scanning. However, after disabling this functionality within Outlook, the problematic emails were resent, and the attachments appeared as expected.
