Outlook Not Working on Mac: Troubleshooting Steps to Get You Back Up and Running

Are you experiencing issues with Outlook not working on your Mac? Whether you're unable to send or receive emails, or the application is crashing unexpectedly, troubleshooting these problems can be frustrating and time-consuming. In this article, we'll walk you through common causes and solutions to help you resolve the issue and get back to your normal email communication.

Check Your Internet Connection

Before diving into more complex issues, make sure your internet connection is stable and working properly. Check your Wi-Fi router, Ethernet cable, or mobile hotspot to ensure you have a strong signal. If your connection is weak or unreliable, it may prevent Outlook from functioning correctly.

Incorrect Account Credentials

Another common cause of Outlook not working on Mac is incorrect account credentials. Double-check that your email address and password are accurate, and make sure you're using the correct login information for your ISP (Internet Service Provider) or network firewall.

IMAP/POP Accounts Require Authentication

If you're using IMAP (Internet Message Access Protocol) or POP (Post Office Protocol) accounts, ensure that authentication is enabled. You can do this by going to Outlook's preferences and selecting the account settings. Make sure 'Use same settings as my incoming mail server' is selected.

Outlook Not Receiving New Emails

If you're not receiving new emails in your mailbox or sending emails to other mailboxes, check if your computer has an active internet connection. You can also try restarting Outlook and synchronizing your accounts to resolve any connectivity issues.

Crashing Issues with Calendar Events

Sometimes, crashing issues may occur due to calendar events with a 'NULL OriginalStart' property. If you're experiencing this problem, try removing the affected calendar event from your account before reconnecting it to Outlook for Mac.

Outlook Not Opening or Crashing Unexpectedly
