The Problem with Multiple Outlook Accounts If you have multiple Outlook accounts, therefore, you will not only have to learn how to manage multiple accounts but also how to manage all of those accounts on multiple platforms. While the multiple versions of Outlook are a bit confusing, the fact that there's both a desktop email client and a webmail service gives users a large degree of flexibility that almost no other email service provider can match. There are now several versions of Outlook available including the desktop version, the Outlook Web App, and the webmail version on where users can sign up for free Outlook accounts. Outlook has been available since the launch of Office 97. It’s easy to see why so many people use Office since it has a product for just about everything: Excel for spreadsheets, Word for document writing, PowerPoint for slideshow presentations, Access for databases, and Outlook for emails. That means 1 in 7 people use Microsoft’s products. Over 1 billion people worldwide use the Microsoft Office suite as part of their digital workplace toolkit.
