Outlook Search does not function

Question

We have several instances of the following error presenting itself in Outlook. It is affecting a wide range of different office suites. We have rebuilt indexing locally and on the exchange servers. That did not resolve the issue. Could you provide some guidance? This appears to be a widespread problem. Thank you, 

Answer 1

Any update on resolving this issue?

Answer 2

Microsoft - any update on issuing a patch for this issue?

Answer 3

Has Microsoft determined a resolution to this issue yet?

Answer 4

Disabling fast search is the quickest workaround I have found.

It is just a registry key which can be rolled out via Group Policy or any other client management tools.

This instantly fixes the issue as a workaround.

HKEY_CURRENT_USER\software\policies\Microsoft\office\16.0\outlook\search

DWORD: DisableServerAssistedSearch

Value: 1
