Seems to be a trend...
 

This just started happening to me yesterday.

Do any of you use iCal Server in an office network? We just upgraded our server to 10.6 and I began testing this app to have a joint office calendar. This was about the time OmniFocus started giving me these errors. But turning iCal Server off and resetting my OF iCal settings has done nothing to alleviate this issue.

TBD, I guess!

/

After reseting sync services & OF iCal settings, try rebooting. OF support supplied several actions to help but none of them were having any affect. I needed to reboot due to another issue I was having and after reboot OF syncing was back. I assume 1 of the OF support recommendations worked it just needed the reboot to kick in.

Same problem here ... So there is no solution to this ???????

This error should be fixed in the latest [URL="http://www.omnigroup.com/products/omnifocus/download/sneakypeek/"]sneaky peek builds[/URL] of OmniFocus 1.8.

It sounds like SyncServices may have gotten corrupted somehow. Resetting your iSync history *should* remedy the problem.
