Summary: This blog will guide you to transfer OST Emails to Office 365 account without any data loss. If you want to know about the import process, then read the complete article to the end.
Microsoft 365 has risen to the top of Microsoft’s cloud offerings. It has hundreds of millions of users globally and provides Microsoft with the most profit. Although Exchange Server is the primary email server used by organisations, Exchange Online, which is included in Microsoft 365 Enterprise and Business, allows enterprises more freedom in how they access their emails.
The mailboxes’ security standards are identical to those of on-premises Exchange Server, but they may be accessed from any device or location. Users must transfer both OST and PST files when migrating from on-premises Exchange to Microsoft 365. The offline data file (OST file) is a copy of the Exchange mailbox data, whereas the online data file (PST file) stores critical emails, contacts, notes, sent items, attachments, calendar information, and so on. Because of the OST file, the Outlook account stays active even when the connection between Outlook and Exchange Server is down. When the connection is re-established, the data is calibrated with Exchange Server. A user may want to import OST to Microsoft 365 for a variety of reasons, including advanced cloud advantages, the avoidance of Exchange outages, the necessity for a secure environment, organisational shifts or migrations, and so on.

The use of a cloud platform like Office 365 to store Exchange mailbox data has several advantages. You may view all Office 365 emails from any computer, anywhere, if you have an internet connection.

One may migrate their Offline Outlook Data File (OST) to Office 365 accounts to help with this, and there are several ways to do so.
There are a few reasons why customers might want to migrate their OST files to Office 365 before that.
- To avoid Exchange crashes and provide a stable platform.
- Because of the benefits of Office 365, there has been a transformation in the organisation.
- After an unintentional deletion, material may be accessed quickly in a secure environment.

The manual methods for importing OST files emails to Office 365 will be discussed in this post. There is no way to directly upload your OST files to your Microsoft 365 accounts. To convert and import/export the data, the user must devise certain workaround solutions.
Method 1: Convert an OST file to a PST file and then import it into Microsoft 365.
The first manual technique is an indirect way in which you convert OST file data to PST and then import the PST file into Microsoft 365 since PST file import is supported by Microsoft 365 Security & Compliance.
The steps for creating PST files are as follows:
1. Select File from the File menu in Outlook.
2. Select Import/Export wizard under Open & Export.
3. Select the ‘Export to a file’ option after launching the Import/Export wizard.
4. Select ‘Outlook Data File (.pst)’ as the second option and click Next.
5. The wizard will display all of the Outlook OST mailbox account’s folders to you. Select Include Subfolders from the drop-down menu and then select Next.
6. To specify the location of the PST file, click the Browse option. Select how you want to deal with duplicate items from the selections. Then click Finish to complete the process.
7. Your OST mailbox account’s data has been transferred to a new PST file.
Note that the above-mentioned approach cannot be used to migrate OST file data like message rules, folder settings, custom views, meeting schedules, and so on.
The second step is utilising either the Network Upload or Drive Shipping methods to import the PST files into Microsoft 365.
Before beginning the operation, make sure the Mailbox Import Export role is assigned to the Microsoft 365 mailboxes. To do so, log in to the account’s Exchange Admin Center, navigate to Permissions, and double-click the mouse to open Organization Management. To save it, go to the Add option, add the Mailbox import-export role, and then click Save.
