FAQ: Why didn't my Vacation Delegate automatically approve reports awaiting my approval?
If you're having trouble with your Vacation Delegate not automatically approving your report, it's likely the report was submitted prior to the Vacation Delegate being set up.
Any reports submitted to you before you or your Domain Admin set-up your Vacation Delegate will remain in your Inbox. Vacation Delegates will only receive reports submitted after this is set up.
So remember, the best way to ensure you don't have any trouble with this is to make sure you clear out you Inbox before you head away on leave!
