Emails from Outlook are successfully attached to corresponding ACT! records.
If an email cannot find a matching ACT! contact, I am offered the option of creating a new contact in ACT! from Outlook, or attaching the email to a different contact. This works without a problem.
I run Outlook synchronization from inside ACT! or from the ACT! Integration Service in the command tray
I get the pop-up "Do you want to synchronize ACT! and Outlook now?"
I click "Yes" but nothing happens, no contacts or calendar are synchronized.
In Synchronization History there are no records under Contacts and Contact_Activity. But there is a log entry under "Activity": It shows Error 1, "Your ACT! username or password is invalid" (Please see attached screenshot)
I have repeatedly confirmed that the database, username and password are correct. And anyway, since email is integrating, that indicates that Outlook and ACT! are communicating.
I have also double-checked all the Integration Preferences including that the integration is from ACT! to Outlook 365.
