Does Outlook client or Exchange have the ability to retry a failed Save action to a calendar folder for a meeting event? The scenario specifically is an instance where a calendar delegate creates a meeting on behalf of the organizer. The attendees receive the invite, accept, and their calendars update, but not the organizer. This also occurs when a delegate sends updates to existing meetings and cancellations.
I am aware of a similar issue with Skype meetings failing to save to the organizer’s calendar. There is a documented workaround advising to lengthen the time delay for AutoSave in the delegate’s Outlook, or to disable the delegate’s AutoSave altogether. Our environment has mixed results.
Currently, our team is deploying Office Update Version 1909 Monthly Channel, which includes an update to the calendar sharing feature using REST instead of MAPI. This update appears to address the very factors in Outlook's design that result in poor performance for delegate-based calendar management.
That having been said, have others experienced this issue where a meeting invite / update sends successfully, but fails to save to the organizer's calendar?
@KenWee Are you referring to the timing for AutoSave? The default time is 3 minutes until it autosaves the draft in the Draft folder of the delegate's Outlook. If you increase the time, that will minimize the chance of the error occurring, but I am not yet certain that prevents it completely. Let me know what you find with the change.
