Unfortunately, due to the underlying speed of Outlook and ACT!, Outlook-To-ACT Migration Professional is fully dependent on the speed of these software packages. Hence, it is recommended that you run the software on a local database using Outlook locally. Otherwise, speed will be a major factor. Outlook-To-ACT Migration Professional is not a speed daemon. We perform a large number of checks before we bring the data over and Outlook in conjunction with ACT! does not promote fast processing.
If you are creating a brand new database, disable Duplicate checking and conversion process will speed up significantly since no need to perform duplicate checking is necessary.
