Since installing ACT! Premium v20, it takes one to two minutes to open the act Address Book. I am using Outlook 2016. This occurs every time a user tries to address a new email. In v19 the same address book, with the same 3200 contacts, opened in less than one second. As a result, none of our ACT! users are able to use the ACT! Address Book (doing so would add 1 to 2 hours to a workday). Swiftpage tech support was unable to help me, and suggested I post my issue here. Does anyone have any ideas?
