How can I extract attachments from Outlook, save a

Question

I am working on a project that requires me to save large numbers of attachments to a folder and filter them.

I can currently save the attachments with the subject of the email as the filename. If there is more than 1 attachment then it saves as the subject line with a (1) or (2) and so on.

I currently have a script that will do most of what I need (Thanks to the help from 0m3r in the replys below)

The last thing I need to complete this script is something that will omit special caracters from the subject line before it uses the subject line as the file name. The problem I am running into is the program does not save files correctly if the subject is a Forward (FW:) or a Reply (RE:) I suspect the ":" is what is breaking the save file. For example if the Subject reads "FW: Here is the file you requested 2017" what I am getting is a file saved as "FW" without a file extensions. What I need is to remove the ":" or the "FW:" so this does not happen.

Can someone provide me with the correction I need to remove special characters from the subject as its converted to the save file name?

I think an Array will be needed to accomplish this but I am not sure how to implament it and what part of the script to add it into.

Something like Array("<", ">", "|", "/", "*", "\", "?", """", "'", ":")

You need to modify your For Each loop, Try this...

Change this

Dim strAtmtName(1)      As String

To this

Dim strAtmtName         As String

And then modify your For Each loop like this

For Each Atmt In atmts
    strAtmtFullName = Atmt.FileName
    intDotPosition = InStrRev(strAtmtFullName, ".")
    strAtmtName = Right$(strAtmtFullName, Len(strAtmtFullName) - intDotPosition)
    strAtmtPath = strFolderPath & objItem.Subject & Chr(46) & strAtmtName

    Dim lngF As Long
    lngF = 1

    If Len(strAtmtPath) <= MAX_PATH Then
        blnIsSave = True
        Do While objFSO.FileExists(strAtmtPath)

            strAtmtNameTemp = objItem.Subject & "(" & lngF & ")"

            strAtmtPath = strFolderPath & strAtmtNameTemp & Chr(46) & strAtmtName

            If Len(strAtmtPath) > MAX_PATH Then
                lCountEachItem = lCountEachItem - 1
                blnIsSave = False
                Exit Do
            End If

            lngF = lngF + 1
        Loop

Answer 2

After some digging aroung looking at several posible options for omiting special characters from the subject line and some toying aroung with the macro I have come up with what seams to work perfectly for what I need.

Thank you 0m3r for your inital assistance in getting this taken care of.

The code below:

1. selcet the folder to save all attachments to.
2. It then pulls the subject line of each email
3. Replaces any special characters I define with "_"
4. Saves the file as the modified subject line.
5. Repeates process for every selected email.

Paste:
