Windows Server 2022 - RDS - Outlook Search

Question

Good morning,

A Server 2022 is having problems with searches in Outlook 365. Permanent RDS environment, 10 users, Windows Search enabled.

Indexing is finished.

I changed the registry key [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Search] "EnablePerUserCatalog"=dword:00000000 To allow you to create indexes accessible to users

Search results appear incomplete: if I search for a term present in the text of an email the email is not present in the search results, it only appears if I search for a term present in the subject. Sometimes among the results I find some messages containing the search term in the text but the results are incomplete.

I have already done index rebuild several times.

I didn't notice any errors in the event log.

Answer 1

Hello,

Here are a few things to consider:

1.Double-check the locations included in the indexing. Go to Control Panel > Indexing Options > Modify and ensure that all relevant Outlook data files (.pst and .ost) are selected for indexing.

2.In Outlook, go to File > Options > Search. Make sure that the options under 'Results' and 'Sources' are set correctly. For example, 'Include messages from the Deleted items folder in each data file when searching in All Items' should be checked if you want to include those in search results.

3.Since you've already modified the EnablePerUserCatalog registry key, consider checking the following keys as well:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration\SharedComputerLicensing - Set to 1 for shared computer activation.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Search - Check for any other keys that might affect search functionality.   4.If using FSLogix, ensure that the Office 365 Container is set up correctly. The configuration should include the VHDLocations for storing the containers and the IncludeOffice365Containers set to 1.

5.In a permanent RDS environment, consider using Cached Exchange Mode with a limited cache size to improve search functionality. This can be configured via group policy or account settings in Outlook.

For further information,

I'm not sure if Outlook uses Windows search instead of its own search engine, because sometimes it happens that search results appear if the search term is present in the subject of the message, but does not return any results if the search term is in the message text.

Sometimes (for older messages, but randomly and rarely) the results appear even if the search term is present in the text
