Solution: Disable Server Assisted Search
The latest outlook version has changed the default search used in outlook and may not be compatible with your exchange version. To disable this new search feature, you will need to edit the registry.
Open Registry Editor by typing ‘regedit’ in Windows Search and clicking Registry Editor.
Navigate to the following Path.
HKEY_CURRENT_USER\software\policies\Microsoft\office\16.0\outlook\search
If the above path does not exist, try this path instead.
HKEY_CURRENT_USER\software\Microsoft\office\16.0\outlook\search
Create a new REG_DWORD inside the search folder: Right Click > New > DWORD
Give it the name: DisableServerAssistedSearch
DisableServerAssistedSearch
Open the new entry and change the Value Data to 1 and click OK.
Restart Outlook and try the search.
