I'm using the template "Post to Slack when an upcoming event is starting soon in Outlook Calendar," trying to integrate a resource mailbox calendar in O365 with a specific slack channel. I tested first with my user, and entering "calendar" in the Calendar Id field and the slack channel in the appropriate field was all it took--everything worked perfectly. I've since changed the O365 connector to use the resource mailbox user; now, when choosing the Calendar Id, there are drop-down options for each of the three that this resource has (Birthdays, Holidays, and Calendar.) I've selected Calendar, and now when I test, I get the following error:
The specified object was not found in the store.
clientRequestId: bea0acf8-fbf4-4825-9a69-81b766f1e41d
serviceRequestId: 9e43332e-7503-70fc-e8dd-3645b1e0ea5b
Is anyone able to assist? Thank you!
