Possible Causes

Identifying the root cause of timeouts is the first step to resolving the issue. Here are some common reasons why Outlook connections to the Exchange server may time out:

• Faulty Add-ins: Adding third-party extensions can interfere with Outlook’s normal operation.
• Firewall or Antivirus Settings: Sometimes, security software can block Outlook or the Exchange server.
