Hi there, 

Welcome to the Box Community, I'm happy to help!

Please be informed that this community is primarily intended for English language speakers. If you are able to post your question in English, the community may be better able to assist. Google Translate or other tools may help! If any community members are able to understand and help, it would be greatly appreciated.

Thanks for posting!

I received an email from a business partner, and the attached file was stored in my BOX. When I tried to open the attached file in BOX, the above message appeared and I was unable to access BOX.

I tried the method described in the workaround, but it didn't work. Please tell me how to access the BOX.

取引先から私にメールが届き、そのメールの添付ファイルがBOXに格納されました。私がその添付ファイルをBOXで開こうとした時に、上記のメッセージが出て、BOXにアクセス出来ませんでした。
対応方法に記載されている方法を実施しましたが直りません。BOXにアクセスする方法を教えてください。
