Why is Outlook Inbox Not Updating? There could be multiple reasons for your Outlook not updating, including connectivity issues, incorrect account settings, or a corrupt Outlook profile. To fix this, first, check your internet connection and ensure it's stable. Next, try updating the Send/Receive settings in Outlook and verify your account configuration. If these steps don't resolve the issue, consider repairing or recreating your Outlook profile or running the Inbox Repair Tool (scanpst.exe) to fix any corruption issues in your mailbox. https://www.limksys.com/outlook-inbox-not-updating-from-exchange/
