outlook pst cloud

The tag 'outlook pst cloud' covers issues where Outlook Personal Folders (.pst) files stored in cloud-synced locations like OneDrive or Dropbox cause application hangs or errors. Recent discussions focus on regressions from Microsoft's January Patch Day, where Outlook Classic profiles with PSTs on OneDrive may stop responding or fail to reopen. These problems are part of a broader set of regressions that prompted emergency out-of-band fixes. The tag is relevant for users experiencing Outlook crashes or freezes when working with PST files in cloud storage, particularly after Windows security updates.
