Yes, you can upload PST files to an Office 365 online archive mailbox, but not directly in a simple way. Office 365 requires specific methods to import PST data into the archive mailbox.
One common approach is using Microsoft Outlook. First, enable the online archive mailbox in your Office 365 account. Then configure your account in Outlook, open the PST file, and manually drag and drop emails into the archive folders. This method works, but it can be slow and time-consuming, especially for large PST files.
Another option is using Microsoft’s network upload or import service, which allows you to upload PST files to Office 365 and map them to archive mailboxes. However, this process can be complex for non-technical users.
A more efficient solution is to use a professional PST Converter Tool. It allows you to upload PST data directly to the archive mailbox while maintaining folder structure and data integrity.
Using BLR Tools makes the process faster, easier, and more reliable, especially for bulk migrations without complications.
