Whether connecting via iOS, Windows 7 or a WebDAV client, you can use the following URL in your WebDAV client: https://dav.box.com/dav


IMPORTANT   On April 30, 2018, we announced our intent to deprecate WebDAV Support effective January 31, 2019.  We are extending support for WebDAV beyond our originally-announced date.  We will provide a more detailed update in the early April, 2019 timeframe.  Get more information here.  

Box recommends using third-party clients for mapping a drive to Mac OS X.


To connect to WebDAV please use the following:

Server: https://dav.box.com/dav
Login: Your Box login email address and password.  
Note: Web browser access is not supported. You must use a WebDAV client.


Known Issues


  1. Because uploads through WebDAV are accomplished in two stages, zero-byte files will be uploaded as placeholders before the final file contents are uploaded. This will make a newly created or uploaded file have two versions and include two upload events in reporting.
  2. Single Sign-On (SSO) is not supported via WebDAV. If SSO is required for account logins, you may use the Create External Password for WebDAV logins. The external password may be created in the Account Settings > Account tab > Create External Password
  3. Only primary addresses are supported for logging in to a box account. Secondary aliases are not supported for logins through WebDAV.
  4. Opening Office and Adobe files (doc, docx, xlxs, pptx, pdf, etc.) may continually prompt for login credentials if the programs are not currently open when downloading a file from Box via a mapped drive. This is a known Microsoft issue that is unrelated to Box’s WebDAV implementation. The password will be saved, so choosing OK will open the file. Additionally, keeping these programs open will avoid the prompt when opening another file with that extension.
  5. Location is not available. Access is denied. If you see either of these when trying to connect with your WebDAV client, it could indicate you have triggered the Captcha on your account. To check and clear the Captcha, login with your web browser to https://app.box.com/ . Try your WebDAV client again and it should work.
