Hello there,
we are running an automated pop3fetcher (for attachments) powered by Chilkat Mail (Active X) on PB 10.5
It works really well, but we now encounter an error on a Windows 2008 Terminal Server machine when no user is logged in and our application is run as an automated task (windows task scheduler -> security options -> ‘Run whether user is logged on or not‘).
I'm using CopyMail() to get the Emails into the Mailbundle oleobject, wich I then test with:
if isvalid(loo_mailbundle) then
The mailbundle being NULL, I checked with GetLastErrorText to find:

I tried solving this issues by using mailman.AddPfxSourceFile() and mailman.SetDecryptCert() respectively, which now results in the same NULL EmailBundle, but I can't seem to be able to find the error in the LastErrorText:

The thing is, as soon as I log in with the user the background task is already running at, it works and even continues to work flawlessly when logging out again, until the task is restarted over night.
Are there any specific Windows services needed to be running?
Maybe someone encountered a similar issue, or sees more in this protocol than me.
Thank you for your time.
