Issues with Microsoft Outlook’s Personal Folders File format—commonly referred to as PST—have been a huge problem for years. Microsoft knows that, which is why Outlook comes with a built-in tool called Inbox Repair to help you fix corrupted PST files.
In most cases, simply running a damaged PST file through the Inbox Repair tool should be enough to patch it up. But sometimes, you must take extra action to recover lost items.
How Outlook PST File Repair Works
Outlookの受信トレイ修復ツールは、コンピューターのMicrosoft Officeインストールフォルダーの奥深くに埋め込まれているため、そこに到達するには少し掘り下げる必要があります。 受信トレイの修復を見つけて起動したら、損傷したPSTファイルを選択して修復するだけです。

2. Open File Explorer. Depending on the version of Windows that you use, navigate through the following folders:
- Windows 64ビット: Local Disk (C:) > Program Files > Microsoft Office > root > Office16
- Windows 32ビット: Local Disk (C:) > Program Files (x86)> Microsoft Office > root > Office16
注: The folder paths above apply to Outlook 2016, Outlook 2019, and Outlook 365. If you use an older version of Outlook, you must select the Office15 (Outlook 2013), Office14 (Outlook 2010), or Office12 (Outlook 2007) folder instead.

Open Microsoft Outlook and it should automatically start using the PST file without issues. You will find a copy of the corrupted PST file (with the .BAK extension) in the same location as the repaired original.
Recover Lost and Found Files
Sometimes, Microsoft Outlook’s Inbox Repair tool may end up repairing a severely damaged PST file. Suppose the tool fails to place any repaired items in their original folders or locations. In that case, it will lump them into a Lost and Found folder or a set of folders under the Recovered Personal Folders ラベル。
You can recover these items by creating a new PST data file in Outlook and moving the contents from Lost and Found or Recovered Personal Folders into it.

Recover Additional Items from PST
Suppose you notice any missing items within the repaired data file. if you also can’t find them inside the Lost and Found folder or under Recovered Personal Folders, you can try retrieving them using the backup copy of the original. Basically, you try to import the contents within the file without duplicating any items that the Inbox Recovery tool has already recovered.
1. Copy the corrupted PST file backup to your desktop.
2。 変更 .BAK extension at the end of the file name to 。PST.
