07:09 PM		EXCHANGE ONLINE SERVICE ALERT Title: Some users are unable to search email stored locally in PST or OST files via the Outlook desktop client ID: EX313982 User Impact: Users are unable to search email stored locally in PST or OST files via the Outlook desktop client. More info: This issue will happen with any account in which email is stored locally in Personal Storage Table (PST) or Offline Storage Table (OST) files, such as Post Office Protocol (POP) and Internet Message Access Protocol (IMAP) accounts. This issue will affect offline searches for data stored in local OST files. If the default search is set to server search, the issue will only affect the advanced search in Outlook. Users may disable or restart the WSearch service while logged out of the Outlook desktop client to resolve the issue temporarily. Current status: The service provider believes that the recent Windows update, KB5008212, contains a code issue in which a user's log-off notifications are not handled correctly by the search indexer, causing email stored locally in PST or OST files not to appear when searching via the Outlook desktop client. They're testing with affected users now to confirm this theory and aid in developing a fix that remediates impact. Scope of impact: Some users attempting to search for email stored locally in PST or OST files via the Outlook desktop client may experience impact. Root cause: The recent Windows update, KB5008212, contains a code issue in which a user's log-off notifications are not handled correctly by the search indexer, causing email stored locally in PST or OST files not to appear when searching via the Outlook desktop client.
