False alarm - Spam Sieve just took a long time to load the Outlook addresses and has now completed the process
SpamSieve is reading the Outlook data using the standard AppleScript command:
get _message's source
You won’t see the problem in everyday use without SpamSieve because you wouldn’t be accessing the message data via script. But if you use AppleScript to read the message data via Script Editor or another app it will behave the same way as if SpamSieve does it. As I said, the sample log shows that Outlook is getting stuck waiting on the server. So either Outlook has the data already and is waiting unnecessarily, or the server is taking a long time to respond, or Outlook is not properly handling the server’s response. My guess is that the issue is with Outlook, not your host, since you aren’t seeing these delays when viewing messages directly in the UI.
Thanks. The sample shows that SpamSieve was waiting a long time for Outlook to respond with the address data. You would need to sample Outlook to see what it was doing during that time.
