检查对Sharepoint文件夹的访问权限/如果该文件夹存在

Question

将SaveAs的简单宏保存为SharePoint的基本excel文件，然后执行其他操作。 当用户可以访问指定的文件夹FLUX PL时，宏可以完美地工作。

ActiveWorkbook.SaveAs Filename:="https://xxxxcorp.sharepoint.com/sites/CEEControlling/Shared%20Documents/Reporting/FLUX%20Analysis/FLUX%20PL/FLUX%20analysis%20PL%20" & Date & ".xlsx", FileFormat:=xlOpenXMLWorkbook, CreateBackup:=False

如果用户没有访问权限（因此他看不到该文件），则该文件将保存为原始文件的一半，因此它已损坏，因此我必须使用以前的版本。

我尝试了包含代码来检查我是否可以访问/该文件夹存在于SharePoint中，但是它给了我

运行时错误'52'：错误的文件名或数字。

mypath = "https://xxxxcorp.sharepoint.com/sites/CEEControlling/Shared%20Documents/Reporting/FLUX%20Analysis/FLUX%20PL"
mypath = Replace(Replace(mypath, "https:", ""), "/", "\")
mypath = Replace(mypath, Split(mypath, "\")(2), Split(mypath, "\")(2) & "@SSL")

If Dir(mypath, vbDirectory) = "" Then
    MsgBox ("Doesnt exist!")
Else:
    MsgBox ("Exists!")
End If

我还考虑过On Error Goto [label]但到出现错误时，该文件已被重命名（原始文件已损坏）。 我将不胜感激。

如果将来有人需要它，我就会开始工作。 我尝试保存它，如果它给我错误，则使用On Error GoTo并打开SaveAs对话框。
