Symptoms
Out of Office Not Routing Properly
Diagnoses
An out of office was set through workspace for User A to redirect all requests to User B. A request was submitted requiring User A which was not redirected to User B forcing me to do a manual redirect.
Resolution
When configuration Out of Office, this will behave more like a "Delegate" instead of a "Redirect" such that both UserA and UserB will see the this task item in their worklist, the task item does not get re-assigned to UserB until an actual "Redirect" is performed either by UserA from his/her worklist, by and Admin from the Global worklist, or perhaps from API.
Are both UserA and UserB using the default worklist filter in the user's worklist (as this can result in different behaviors if it had been modified). This default filter will show items belonging to the user including items that was delegated to the user (usually associated with using Out of Office). The default filter is:
Worklist Item Status Equals Available -
Worklist Item Status Equals Open Or
Worklist Item Owner Equals Me And
Worklist Item Owner Equals Other Or
Additionally when setting Out of Office, the delegated user do not receive email task notification only the original worklist item owner will. At this time, this is a current product enhancement that is on the roadmap to be included in a future K2 update.
