Try this first
- Ask IT to confirm Full Access plus Send As, not just Send on Behalf
- Close Outlook, wait a few minutes and reopen so tokens refresh
- Test in Outlook Web; if it works there, it is local cache
- Remove and re-add the mailbox manually via account settings
When to bring us in
If permissions are confirmed but still empty, or Send As bounces.
