New Search service applications cannot be created successfully starting with the March 14, 2023 update KB5002355. In Central Administration, their Search Service Application: Search Administration page reports: "The search service is not able to connect to the machine that hosts the administration component."

SharePoint Server Subscription Edition

KB5002375 addresses a spoofing vulnerability in Microsoft SharePoint Server: CVE-2023-28288.

The SharePoint Server Subscription Edition package KB5002375 includes the following improvement and fixes:

  • Ensures that the SharePoint farm service account belongs to the database owner group for the subscription settings service application database.

  • Fixes an issue where deleting the document library web part’s title in edit mode displaces the See all button and makes further title changes impossible.

  • Fixes an issue where the document library web part keeps its previous title after its target library is changed.

  • Fixes an issue where file uploads in the modern document library web part fail for files larger than 25 MB.

  • Fixes an issue where edits made through the Document Information Panel (DIP) in Microsoft Word do not appear in SharePoint.

  • Fixes an issue where Office Online Server cannot provide a preview of a document containing Korean characters.

  • Fixes an issue where selecting Authenticated on Central Administration’s Outgoing E-Mail Settings page leaves the username and password fields disabled.

  • Fixes an issue where uploading files to a shared My Site folder leaves the OneDrive Next Generation Sync Client stuck in "Sync pending".

  • Fixes an issue where, with multiple external lists, only one list can display its items in the display form. Items can now be displayed in all the forms.

  • Fixes an issue where selecting a resolved user in a PersonWithoutPresence field briefly produces "No Results" instead of immediately filling the field.

  • Fixes an issue where Internet Explorer cannot open a modern site.

  • Fixes an issue where the Text web part keeps showing the Loading spinner rather than content pasted from the Microsoft Word or Microsoft OneNote desktop application.

  • Fixes an issue where the document library web part fails to report a name conflict when an existing file or folder cannot be uploaded.
