Perhaps you'd like to increase the frequency of synchronisation between Outlook and Workbooks to ensure that both systems reflect the most recent changes to records.

To do this, simply right click on the Outlook Connector icon from the taskbar and click Options...

In this menu, select Synchronisation from the side, then adjust the sliders to change the frequency of synchronisation.

NOTE:  To eliminate the popup each time synchronisation is run, we recommend that you uncheck the Show progress during automatic synchronisation box.
