Author: Kelly Last Modified: 2024-07-24

Outlook's auto-capitalization feature helps correct capitalization errors as you compose emails, such as changing CApitalization to Capitalization. However, there are times when this feature might not be desirable, such as when typing specialized terms like ICBank, which should not be automatically altered to Icbank. This guide will show you how to easily turn the auto-capitalization feature on or off in Microsoft Outlook, giving you control over how your text is formatted.
