Using an O365 resource mailbox in a workflow

(0) ShareShare
ReportReport
Posted on by 12

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!

    Hi @soundsliked ,

     

    Could you clarify what's resource mailbox user?

    It's a room mailbox. We use the calendar for scheduling things.

     

    Thanks!

    Could you show the action that generates errors?

    Open OWA and check if you see the room calendar in the list of "My Calendars".

    Also check if you can create an event in this calendar.

    Yes, I can do that. I have rights to impersonate the account and also full delegation. Thank you!

    I've just tried to select the room mailbox calendar in the field "Calendar Id" of the "When an upcoming event is starting soon (V3)" trigger.

    No problems with this test flow at all.

    Thank you. What could be causing the error, then? I have full access to the mailbox and also to the slack environment. The room mailbox account is used in the O365 connector. This worked for me when I used my own account as the connector and "Calendar" as the ID. The value I'm using now was pulled from a dropdown of accurate options, so I know that the connection to the mailbox is working. I've been trying to get this to work for days.

    Try to use your personal account in Office 365 connector.

    Yes, that works, but it does not allow me to select the resource mailbox in that case.
