Yes, it’s possible to change an Outlook OST to PST without losing data, but the method depends on account type and file health.
1.[size=1] [/size]If the original mailbox is accessible in Outlook (Exchange, Microsoft 365, IMAP):
2.[size=1] [/size]Open Outlook with the active profile.
3.[size=1] [/size]Go to File > Open & Export > Import/Export > Export to a file > Outlook Data File (.pst).
4.[size=1] [/size]Select the mailbox or specific folders, enable “Include subfolders,” and choose a safe location.
5.[size=1] [/size]Finish to create a PST. This preserves emails, folders, calendar, contacts, and metadata like read status in most cases.
·[size=1] [/size]If the mailbox/account is not accessible, but Outlook still opens the profile:
·[size=1] [/size]Create a new PST (Home > New Items > More Items > Outlook Data File).
·[size=1] [/size]Drag-and-drop folders from the OST mailbox into the PST, or use Copy Folder. This keeps structure and content. For large mailboxes, move in batches.
·[size=1] [/size]If the OST is orphaned or corrupt:
·[size=1] [/size]Reconnect to the server so Outlook rebuilds a fresh OST, then export to PST.
·[size=1] [/size]If reconnection is impossible, consider reputable OST-to-PST utilities that read orphaned OST files in read-only mode to prevent data loss.
Tips to avoid loss: ensure stable Outlook, disable conflicting add-ins, back up the PST after export, and verify item counts/folder sizes before and after conversion.
