Clearing your Outlook cache removes temporary files and data stored to help the program run faster. While this can free up memory and resolve performance issues, you might lose some personalized settings such as your email signature or custom search folders. In most cases, emails and attachments are not affected as they are stored on the server, but items cached locally (like offline mail) could be removed. Before clearing your cache, ensure important data is backed up or synchronized to avoid any unintended loss.
