Many businesses are moving to cloud platforms such as Microsoft 365. If you are moving to Office 365 or currently using it and have old or important data in PST files and are looking for a method to upload it to Office 365 mailboxes, then this post is for you. Below, we have discussed step-by-step how to import PST to Office 365.<\/p>\n<h2><strong>Overview of PST file and Microsoft 365<\/strong><\/h2>\n<p><strong>PST file<\/strong><\/p>\n<p>A personal storage table file (PST) stores contacts, calendars, attachments, and other data elements. Once the PST file is created, the user can easily open it in all Outlook versions.<\/p>\n<p>In the local system, managing multiple PST files can be a very difficult task for users; therefore, many organizations want to migrate their data to Office 365.<\/p>\n<p><strong>Office 365<\/strong><\/p>\n<p>Microsoft 365 is a cloud-based service consisting of productivity applications that are designed for enterprises, businesses, and individual users.<\/p>\n<p>It has multiple features that help users to send and receive emails, schedule your calendar, meetings, chats, create tasks, etc.<\/p>\n<p>It has a bundle of Microsoft apps, such as Excel, PowerPoint, SharePoint, OneDrive, Teams, and many more.<\/p>\n<h2><strong>Need and Method to Import PST files in Exchange Online<\/strong><\/h2>\n<p>There are many reasons why users or organizations move their data to Office 365 cloud storage. Such as<\/p>\n<p><strong>Improved Performance<\/strong><\/p>\n<p>If you have saved PST files in your system, it takes up your system space. Also, there may be a chance of file corruption in case of accidental shutdown or any other issue. Multiple PST files in outlook can slow down the performance. So, it is better to import PST to Office 365 for better performance and it also saves your system storage space.<\/p>\n<p><strong>Anywhere Accessibility<\/strong><\/p>\n<p>Outlook application is available for Mac, Windows and mobile but it requires installation. For M365 users, you just need to log in to your account from Browse and use any online Microsoft service like Outlook.<\/p>\n<p><strong>Restore Data<\/strong><\/p>\n<p>If you accidentally deleted your PST file data, then you will hardly be able to restore it. While Microsoft provides 30 days to restore file or data without any additional cost.<\/p>\n<h3><strong>Method 1: Using Outlook Import\/Export Tool<\/strong><\/h3>\n<p>This is a manual method and best for those who want to export one by one file.
