Hi, I have been using DCS 7.0 for a while and it works great. But there is one issue I would like to have clarification. I assume server maintains inbox for all its principals. With that assumption, *Use case is as follows:* * Organizer A sends an invite to attendee B * Organizer A receives a success response from Server. *Now my question is:* Will the server update the inbox of B before sending the success response to A or will it be updated sometime after? *Reason I am asking:* In my case, A sends a client side notification to B to sync with server after receiving the success response. But some of the time, B is not getting the updates after syncing with server. If B syncs again after 5 - 10 secs, then it gets the update. Could you please provide some pointers? Best Regards, Gaurav Jain PS: Thank you for DCS.
