Outlook mail search issue.


Please follow below steps to troubleshoot ZCO Search issues

1) Windows search service is enabled.

2) Check for the ZCO related registry entries are present

a) If OL is Click To Run, Outlook 32 bit, Windows 64 bit

HKLM\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY\MACHINE\Software\Wow6432Node\Microsoft\Windows\Windows Search\Preferences{D00FDE68-3E80-4f8c-899D-D9DD16BA7D1D} = 1
HKLM\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY\MACHINE\Software\Wow6432Node\Microsoft\Windows\Windows Search\Preferences{FA9628A0-F223-4d5d-B314-E01BC8100572} = 1

b) If OL is Click To Run, Outlook and Windows have same bitness (Wow6432Node would be absent)

HKLM\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY\MACHINE\Software\Microsoft\Windows\Windows Search\Preferences{D00FDE68-3E80-4f8c-899D-D9DD16BA7D1D} = 1
HKLM\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY\MACHINE\Software\Microsoft\Windows\Windows Search\Preferences{FA9628A0-F223-4d5d-B314-E01BC8100572} = 1

c) If OL is not Click To Run, Outlook 32 bit, Windows 64 bit

HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\Windows Search\Preferences{D00FDE68-3E80-4f8c-899D-D9DD16BA7D1D} = 1
HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\Windows Search\Preferences{FA9628A0-F223-4d5d-B314-E01BC8100572} = 1

d) If OL is not Click To Run, Outlook and Windows have same bitness (Wow6432Node would be absent)

HKLM\SOFTWARE\Microsoft\Windows\Windows Search\Preferences{D00FDE68-3E80-4f8c-899D-D9DD16BA7D1D} = 1
HKLM\SOFTWARE\Microsoft\Windows\Windows Search\Preferences{FA9628A0-F223-4d5d-B314-E01BC8100572} = 1

3) Make sure new mails are getting indexed by enabling SearchProtocol Log and checking the log.

4) If the problem is due to search slowness while items are still being indexed, it could be due to AutoRecon reindexing all the mails. This normally happens every 72 hours. This also can be verified by enabling SearchProtocol Log. Please check if the problem happens at certain times every three days. The slowness will be more pronounced in bigger accounts. If the user search activity coincides with the period during with Autorecon reindexes all mails, slowness or partial results will be observed. The solution is to disable AutoRecon in the registry.

1.Steps to disable the automatic reconciliation

If you enable this policy setting, automatic reconciliation will be turned off.

If you disable or do not configure this policy setting, Outlook will reconcile its index every 72 hours.

Registry Hive HKEY_CURRENT_USER Registry Path software\policies\microsoft\office\16.0\outlook\search Value Name recondisable Value Type REG_DWORD Enabled Value 1 Disabled Value 0 Please refer the below link for more reference [ https://getadmx.com/?Category=Office2016&Policy=outlk16.Office.Microsoft.Policies.Windows::L_TurnOffAutomaticSearchIndexReconciliation | https://getadmx.com/?Category=Office2016&Policy=outlk16.Office.Microsoft.Policies.Windows::L_TurnOffAutomaticSearchIndexReconciliation ]

The Registry Path for outlook versions

Outlook 2010 software\policies\microsoft\office\14.0\outlook\search Outlook 2013 software\policies\microsoft\office\15.0\outlook\search Outlook 2016 software\policies\microsoft\office\16.0\outlook\search Outlook 2019 software\policies\microsoft\office\16.0\outlook\search Office 365 software\policies\microsoft\office\16.0\outlook\search
