Originally assigned to: @aluxnimm on GitHub.

Some times when de sync starts, the Outlook becomes completly frozen (about 40 seconds) after this the Outlook works fine, until next sync.
I'm using Outlook Professional Plus 2013, OutlookCalDavSynchronizer-0.99.4, Google Agenda.

I can see the following errors within log.txt:

ERROR 2015-07-24 13:27:59,091 [VSTA_Main] neric.Synchronization.States.StateBase6 .

@aluxnimm commented on GitHub (Jul 25, 2015):

Hi,

I suppose that the error is not the reason for the freeze. Usually such an error just causes that the Appointment is skipped.

Please provide the whole log file. That should help to find the reason for the freeze
