32bit Outlook script in Office 2021 64bit

Question

I have this script that I used for years which stores emails from outlook in a folder on the hard disk for archiving. It always worked great, but no I changed to Office '21 64bit and I get an error message compiling. I have seen similar questions but I'm a total noob, so the question is, can somebody point me to what needs to be changed. The following lines get flagged:

**Private Declare Function lstrcat Lib "kernel32" Alias "lstrcatA" (ByVal lpString1 As String, ByVal lpString2 As String) As Long

Private Declare Function SHBrowseForFolder Lib "shell32" (lpbi As BrowseInfo) As Long

Private Declare Function SHGetPathFromIDList Lib "shell32" (ByVal pidList As Long, ByVal lpBuffer As String) As Long

Private Declare Sub CoTaskMemFree Lib "ole32.dll" (ByVal hMem As Long)**

Any input really much appreciated...
