Summary: For hassle-free, safe and secure migration, you need a PST to Office 365 migration software. However, choosing the best software for the PST to Office 365 migration job that can overcome the limitations of manual methods and ensure the migration to Office 365 with complete integrity is not an easy task. In this blog, we have shared one of the best PST to Office 365 migrator tools that you can use to move single or multiple PST files directly to user’s mailboxes in a few clicks.
Although Microsoft 365 or Office 365 (Exchange Online) allows administrators to upload and import Outlook Personal Storage Table (PST) files to user mailboxes, the process is painstakingly tedious and involves too many manual steps.
In this article, we have shared why you need a PST to Office 365 migration software and learn about the best software to migrate PST files to Office 365 quickly and efficiently.
Reasons to Use a PST to Office 365 Migration Software
Unlike Outlook, importing PST files into Office 365 is more complicated and slow due to the security and compliance reasons. For instance, the manual Network Upload method involves creating the PST import job, downloading AzCopy (a command line-based tool) to upload the PST files to Azure Storage, and then creating and uploading the mailbox mapping file (CSV) to O365. The process does not end here because you further need to validate the mapping file, fix issues (if any), and then start the import job to complete the PST to Office 365 migration.
Below is the diagrammatic representation of the import process via the Network Upload method.
Similarly, if you choose the Drive Shipping method, you need to copy the PST file to a BitLocker-encrypted storage drive, ship it to one of Microsoft’s data centers, pay them $2/GB of PST file or $2000/1 TB PST file and then wait for them to upload the PST files to Azure Storage on your behalf. However, you still need to create an import job, upload CSV mailbox mapping file, and upload it to Microsoft 365 to start the import process.
But you can’t ignore the limitations that these manual methods have. For instance, you cannot upload or migrate PST files larger than 20 GB. Also, any mail items larger than 35 MB are skipped by default (unless you increase the limit to a maximum of 150 MB). Further, Drive Shipping may take several days to weeks. Depending on your location, it may also raise data security and compliance issues, as your drive may cross several borders to reach the destination location.
You can overcome all the limitations using a PST to Office 365 migrator tool. It can help you import single or multiple PST files directly to Microsoft 365 users’ mailboxes. A PST to Office 365 migration software makes this job much easier by removing the intermediate steps and overcoming the limitations.
Unlike the Network Upload and Drive Shipping methods to upload and import PST files into Office 365, a PST to Office 365 migration software can directly import PST files into Microsoft 365 users’ mailbox in a few clicks. You can upload PST files up to 50 GB with no limit of message size. You only need the Microsoft 365 user or global administrator’s credentials.
