Microsoft says that there is only one known issue in this update, where Microsoft Outlook search may not show recent emails.

“Recent emails might not appear in the search results of the Microsoft Outlook desktop app. This issue is related to emails that have been stored locally in a PST or OST files,” explains the KB5008353 release notes.

“It might affect POP and IMAP accounts, as well as accounts hosted on Microsoft Exchange and Microsoft 365. If the default search in the Microsoft Outlook app is set to server search, the issue will only affect the advanced search.”

To mitigate this issue, Microsoft recommends users disable Windows Desktop search, which will force Microsoft Outlook to use its built-in search feature.
