Compatibility and competition have long made it difficult to sync a calendar from Microsoft Outlook with an operating system like Apple's iOS. This has forced users of both to defer to using one calendar or even juggling between two competing schedules featuring different commitments.

But in recent years, companies have developed workarounds and even features dedicated solely to connecting software and apps from competing brands. 

That's true of Outlook, which allows you to connect its Microsoft driven calendar to your Apple iPhone, ensuring all your events, calls, and meetings aren't forgotten, whether you're at home or on the go.

Here's how you can ensure you have access to your Outlook calendar on your iPhone.
