The mailbox is either inactive, soft-deleted, or is hosted on-premise.

I've got this error when running a flow.

The flow runs fine on DEV, TST, but not on PRD.

The flow takes exact the same user and that's me.

The step gets his data from an array, transforms it and uses it in the step "Get mail tips for a mailbox (V2)".

When copying the exact same steps into a seperate flow, it all works fine (even on the PRD environment).

What can be the issue?

- User (me) has active Microsoft license

- Works in DEV & TST

- Steps work in Seperate flow

The steps I have in the flow:

1. Initialize variable with following data: (this is some sample data)

[
  "Joost Cuppes 1",
  "joost.cuppes@microsoft.com",
  "Joost Cuppes 2",
  "joost.cuppes@microsoft.com",
  "Joost Cuppes 3",
  "joost.cuppes@microsoft.com",
  "Joost Cuppes 4",
  "joost.cuppes@microsoft.com",
  "Joost Cuppes 5",
  "joost.cuppes@microsoft.com",
  "Joost Cuppes 6",
  "joost.cuppes@microsoft.com",
  "joost.cuppes@microsoft.com"
]
2. Get mail tips from a mailbox (V2) with the following input:
- variables('ApproverContactsInfo')[1]
As this is an array it will take the second value in the list.
 
I have also put an compose action in between as a test, but also doesn't work.
 
Thought maybe I could copy the flow and try that, but also error.
 
Strangest thing is that it does work (same exact code) in PRD in a simpler flow.
