AppleScript Messages not Working in Mail

Turns out to be more syntactical of an issue. To get and use the network path I had to use:

set attachmentsFolder to ("Volumes:Accounting:Expenses:" as string)

Setting it to String rather than Text, and placing it inside of the on perform mail action.

The first time I ran it there was a security prompt asking if I wanted to allow access to the network folder.

The final script is:

using terms from application "Mail"
	on perform mail action with messages these_messages for rule this_rule
		set attachmentsFolder to ("Volumes:Accounting:Expenses:" as string)
		tell application "Mail"
			repeat with theMsg in (get selection)
				set theAttachments to theMsg's mail attachments
				repeat with theAttachment in theAttachments
					set originalName to name of theAttachment
					set savePath to attachmentsFolder & originalName
					save theAttachment in file savePath with replacing
				end repeat
			end repeat
		end tell
	end perform mail action with messages
end using terms from

Now I have to figure out how to get it to work consistently. That will be a different post though.

Next evolution of insight. Looks like this is an issue of saving to a network location rather than locally on the Mac. If I use the following everything works fine.

set attachmentsFolder to (((path to home folder) as string))

Note: at this point I am using this thread to document my experience hoping to help others. I am looking forward to any contributions that others can provide.

Some additional detail. I added a Try catch around the conflict line and then "display dialog" the error string. That gives me the following.

Can’t get «class mssg» id 825282 of «class mbxp» "INBOX/Expenses" of «class mact» id "BB40674E-77B4-40B3-AD07-90C3BE3F8719".

The Expenses subfolder of INBOX is where I am running the script against with Apply Rules.

I have managed to make progress on this one, though the approach might need some reworking when it comes to the final script run from Mail Rules. There is still a problem though with the very last step of saving to the file system.

Here is the new version of the original script based on a version that uses the selected message and then Apply Rules in the Messages menu of Mail.

using terms from application "Mail"
	on perform mail action with messages these_messages for rule this_rule
		set attachmentsFolder to (((path to home folder) as string) & "Volumes:Accounting:Expenses:")
		tell application "Mail"
			set theCount to count of (get selection) -- If there are more than one we need to iterate through them
			repeat with theMsg in (get selection)
				set theAttachments to theMsg's mail attachments
				set theAttachementCount to count of theAttachments
				repeat with theAttachment in theAttachments
					set originalName to name of theAttachment
					set savePath to attachmentsFolder & originalName
					try
						save theAttachment in file savePath
					on error errStr number errorNumber
						display dialog "Error On Save Attachments:" & linefeed & linefeed & errStr
					end try
				end repeat
			end repeat
		end tell
	end perform mail action with messages
end using terms from

Some points to note that I am still learning is how the file system works, which might be the part causing my my issues in this current script. When I got to run the following:

save theAttachment in file savePath

I get the error: Mail got an error: AppleEvent handler failed.
