Updated On - December 18, 2023 by Henry Bray | Reading Time: 8 minutes

Emails are the backbone of any modern-day communication, personal or professional. With the advent of cloud-based email services, businesses and individuals have been flocking towards services like Office 365. One major challenge in switching to Office 365 is migrating the data from existing email clients, such as Microsoft Outlook. PST (Personal Storage Table) files are commonly used in Microsoft Outlook to store emails, contacts, and other data. Several PST to Office 365 migration tools have been developed to ease the migration process, each with its unique features and capabilities. This blog post will discuss the best Office 365 migration tools in the current market.

Although it is technically possible for administrators to import Outlook Personal Storage Table (PST) files into user mailboxes using Microsoft 365 or Office 365 (Exchange Online), doing so requires too much time and effort. Also, if you choose to go with any manual ways, chances are you are risking your data. There are many drawbacks, limitations, and technicalities associated with the manual ways that professionals avoid.

Reasons to Use a PST to Office 365 Migration Software:

Due to security and regulatory concerns, importing PST files into Office 365 is more time-consuming and laborious than importing them into Outlook. For instance, if you want to use the manual Network Upload approach, you’ll need to create the PST import task and then use AzCopy (a command line-based application) to upload the PST files to Azure Storage; and last, you’ll need to create and upload the mailbox mapping file (CSV) to O365. You must validate the mapping file, resolve any errors (if any), and initiate the import task before your migration from PST to Office 365 is complete.

 

If you opt for Drive Shipping, you’ll need to back up your PST files to a BitLocker-protected storage drive, send it to one of Microsoft’s data centers, pay $2 per gigabyte (GB) or $2,000 per terabyte (TB) of PST files, and then wait for Microsoft to upload them to Azure Storage on your behalf. However, to initiate the import process, you must create an import task and then upload a CSV mailbox mapping file to Office 365.

 

However, the shortcomings of such manual approaches must be overlooked. In particular, PST files greater than 20 GB cannot be uploaded or migrated. Mail attachments greater than 35 MB are automatically deleted (unless you increase the limit to a maximum of 150 MB). In addition, the Drive Shipping process could take a few days to a few weeks. Your disc may span multiple countries before reaching its destination, creating data security and compliance concerns.

One solution is to use a PST to Office 365 migration tool, which will allow you to bypass these restrictions. It facilitates the import of single or multiple PST files into users’ mailboxes in Office 365. Using import PST to Office 365  program streamlines the process by skipping the middleman and removing the restrictions. That’s why we know about the best Office 365 migration tools.
