Solution for “The file cannot be used because it was created for a different user”? issue

An OST file which is Offline Storage Table is created by Outlook in local storage (Hard drive) for every MS Exchange user to provide local access to data without the need of an active connection to MS Exchange Server all the time. This file is updated to MS Exchange Server by syncing when you are connected to Server. But the OST file itself may get corrupted after a while due to many reasons such as hardware and software failures.

  • Due to synchronization issues.
  • Outlook OST files size limitations that can cause corruption of OST file.
  • Outlook Add-ins may cause issues that result in corrupt OST files.

We may face other issues as well apart from the above mentioned issues that can result in such error message. Let’s take an example where your mailbox on MS Exchange server has been deleted accidently and a new mailbox has been created. Now, the old OST file will not be connected to that mailbox and hence will get error message as “The file cannot be used because it was created for a different user” when you try to access that file through Outlook.

  1. Convert the OST file to PST file using EdbMails OST to PST Converter.
  2. Then import the PST file to Exchange Server with Powershell using the command
    New-MailboxImportRequest -MyMailbox -FilePath C:\RecoveredPSTFiles\Recovered.pst -TargetRootFolder.
