檢查對Sharepoint文件夾的訪問權限/如果該文件夾存在

Question

將SaveAs的簡單宏保存為SharePoint的基本excel文件，然后執行其他操作。 當用戶可以訪問指定的文件夾FLUX PL時，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

如果用戶沒有訪問權限（因此他看不到該文件），則該文件將保存為原始文件的一半，因此它已損壞，因此我必須使用以前的版本。

我嘗試了包含代碼來檢查我是否可以訪問/該文件夾存在於SharePoint中，但是它給了我

運行時錯誤'52'：錯誤的文件名或數字。

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

我還考慮過On Error Goto [label]但到出現錯誤時，該文件已被重命名（原始文件已損壞）。 我將不勝感激。

如果將來有人需要它，我就會開始工作。 我嘗試保存它，如果它給我錯誤，則使用On Error GoTo並打開SaveAs對話框。
