This article describes update 4018303 for Microsoft Outlook 2013 that was released on April 3, 2018. This update also applies to Office Home and Student 2013 RT. This update has a prerequisite.

Be aware that the update in the Microsoft Download Center applies to the Microsoft Installer (.msi)-based edition of Office 2013. It doesn't apply to the Office 2013 Click-to-Run editions, such as Microsoft Office 365 Home. (How to determine?)

Improvements and fixes

This update fixes the following issues:

  • The custom forms with Visual Basic Script (VBScript) doesn't run in shared calendars in Outlook.

  • When you send an email from a shared mailbox, the email appears in wrong Sent Items folder in some scenarios.

  • Outlook crashes on startup and opens in safe mode when your preferred language list is set to a language that doesn't have a Local ID Values (LCID). For example, your preferred language is set to Javanese or Malagasy.

  • You see that authentication prompts appear behind the active Outlook window and cannot be accessed.

How to download and install the update
