FAST Search doesn't work with certain search terms (on-premise Exchange 2019 CU11)

I'm seeing a curious problem with FAST search in Outlook (2019 and 2016) with an on-premise 2019 Exchange server (CU11):

A user was searching for an E-Mail by someone named Carmen and received the error: "We're having trouble fetching results from the server... > Let's look on your computer instead"

Unbenannt

FAST Search generally works though, only variations of this search term result in the above error message. The user tested a bit, these are the results:

  • ca – worked
  • car - worked
  • carm – didn't work
  • carme – didn't work
  • carmen – didn't work
  • carmen. – didn't work
  • carmen.g – didn't work
  • carmen.gy – worked
  • carmen.gyo - worked

When the user searches via OWA, it all works fine. When I search for the same word in my Outlook, it also works fine (although I obviously don't have the same e-mails in my mailbox).

Has anyone else encountered this?

    Issue Symptom:

    A user was searching for an E-Mail by someone named Carmen and received the error: *"We're having trouble fetching results from the server... > Let's look on your computer instead"
    No issue in OWA. Only affects the particular user.

    Resolution:

    Selecting "All Outlook items" instead of "Current Mailbox" fixes the problem.
