set selectedMessages to every message of mailbox "aaa"

In the asker's code, the selected messages were passed by a Mail rule.

The exact code is available in the thread of macScripter : http://macscripter.net/viewtopic.php?id=45420

I'm reluctant to reproduce it here as it's not mine.

Since my late message, I made other tests.

The unique setting which work is :

set attachmentsFolder to path to downloads folder as text

With the setting which I used for years :

set attachmentsFolder to (path to documents folder as text) & "Attachments:"

it continue to fail.

It's really puzzling because all the tested folders have the same permissions:

me : read-write

everyone : unauthorized access (translated from the french Accès interdit)

I have no idea of what may explain that.

Yvan, wouldn’t you also need something like ‘select message 1 of mailbox "messageStore"’? How else would you programatically select as a ‘selection’?

I’m surprised it worked though!
