Sharepoint 2013在线添加网络位置

我已将Sharepoint联机文档库添加到我的Windows 10 Pro(x64)1703计算机中.

I have added a Sharepoint online document library to my Windows 10 Pro (x64) 1703 computer.

几天后，我被拒绝访问.错误消息说:

After a couple of days I get access denied. The error messages say's:

\\ larandeab.sharepoint.com@SSL \ DavWWWRoot \ sites \ central-fillagring \ Delade dokument \ IT不可用.也许您没有使用此资源的权限.向服务器管理员寻求帮助.

访问被拒绝.在打开此站点上的文件之前，必须首先将其添加到``受信任的位置''列表中，然后转到该站点并选择自动登录选项.

Access denied. Before you can open files on this site, you must first add it to the Trusted Places list, go to the site and select the automatic login option.

但是我已经将URL添加到受信任的站点"中.我绝对有权访问该网站.

But I already have the URL added to Trusted Sites. I definitely have access to the site.

我已尝试在Internet选项中激活"使用当前用户名和密码自动登录". b在受信任的站点上.

I have tried in Internet Options to activate "Log in automatically with the current username and password" b on Trusted Sites.

重新启动无济于事.

在控制面板，自动认证凭证和Windows凭据中，我添加了信息.

In the control panel and autenticationcredentials and windows credentials I have the information added.

唯一有效的方法是删除网络位置，然后使用Internet Explorer转到共享点站点，然后单击以使用Explorer打开.然后，我可以再次添加网络位置.但是..过了几天，我无法再次访问它.

Only thing that works is to delete the network location, then go to the sharepoint site with Internet Explorer and click to open with Explorer. Then I can add the Network location again. But.. after a couple of days I cant access it again.

为什么?
