Do you encounter performance issue after installing updates? What’s the detailed version of Outlook?
The performance issues may be caused by many conditions:
- Large Personal Folders files (.pst) or Offline Folder files (.ost)
- Third-party add-ins
- Antivirus software interaction
- Windows Search or Windows Desktop Search indexing
- Many Really Simple Syndication (RSS) feeds
- Online mode with Exchange server
- Damaged Outlook messaging profile
