Outlook Connector Attempts To Set ACLs When Searching For Shared Calendars Causing Long Delays (Doc ID 1303222.1)

Oracle Communications Connector for Microsoft Outlook - Version 7.0 and later

With MS Outlook, there is a limitation where you must search by the calendar owner name when searching for calendars.  You cannot search by calendar name or ID.  Convergence allows searching by calendar name so it is much more user friendly.

Because of this limitation, performance is affected where the searches can take a long time to return results.

For example:

We created an account called resourcemaster which owns all of the resource calendars.
This was to ensure that all resource calendars have an owner who is not a regular user.

Now, every resource calendar that gets added makes it that much slower to search in Outlook.  This is because you must search by owner name and therefore, potentially return EVERY resource calendar in the system (and we have hundreds now and growing).

Also, when searching for the calendar in Outlook, it looks like Outlook is trying to set some property for EVERY resource calendar as a test for whether or not you can subscribe to it, in order to determine if you should see it or not in the list (it doesn't show calendars to which you cannot subscribe).  So, it appears as if the following is happening in Outlook:



Due to the fact that all resource calendars are owned by one user and then Outlook seems to iterate over every single calendar, it can take over 5 minutes for the search to return during busy hours.  This causes a lot of frustration to the end user and causes many users to just quit/kill the search.
