[gMail] 奇怪的錯誤訊息「-ERR Command not understood」

話說我一直用 Outlook 接收 gMail 跟 台南信箱 ,台南信箱大概在很早 google 還沒有託管信箱上限時,就給 google 託管了,大概是在 2007/02/05 開始託管的。

在 2015/01/21 以後,台南信箱忽然無法從 pop.gmail.com 接收到郵件,但是我的 gMail 則仍然可以從 pop.gmail.com 收到郵件。
使用 Internet Explorer / Chrome 登入此信箱仍可正常使用。比對過兩邊 pop 的設定都完全相同。
首先以為是 outlook.pst 問題,用 scanpst.exe 掃瞄並修復,結果還是一樣。
使用 Outlook 追蹤郵件功能,紀錄到下面的資訊 (OPMLog.log):

所以可以很明確看出,Outlook 登入驗證是通過的,但是送出 STAT 命令後,回應不明白此命令。
比對正常接收郵件的 gMail ,這邊則可正常回應。
最後是把 Outlook 2013 台南郵件 的帳號砍掉重建,就正常使用了,推測可能是 Outlook 裡面自己的問題。

因為 google 都找不到相關可參考資訊,分享在此大家參考一下。
