I figured out the cause of it... Some exchange servers do not enforce POP3 protocols...
Here is an article on resolving it:
http://technet.microsoft...us/library/aa996686.aspx Basically, when messages would not end in the correct ending, VisualCron would throw the error and deactivate the trigger.
After repeated testing, I figured out it was dying at the same message each time... So this is probably not something VisualCron should address. The timeout setting is sufficient.
Sorry for the trouble.
It would be nice to limit the number of concurrent connections at a time... I.e. If I have 10 triggers set against one Pop3 connection, they all seem to run at the same time. I know I can set intervals up to help this, but it feels like the connection should have a queue as well.
Just a thought.
Thanks again for a great product!
