Challenges Users Face When Try to Converting OST Files Manually

When Outlook is associated with the Exchange, the users can undoubtedly recreate OST data files with no issues. But in case your Exchange Server is down either temporarily or permanently, it’s not possible to re-create OST files. In such a scenario, your offline Outlook data file needs an OST to PST Converter tool. There are some challenges users face when manually trying to convert OST files to PST.

  1. Same Exchange User Account is Needed:  Users can’t access an OST file with another account or a different Exchange account. It is only accessible with the Exchange account that was used to create it. All I want to say is only Exchange-connected Outlook users will be able to convert their OST file into PST format.
  2. Corrupted OST file Conversion is not Possible: You know that Outlook can’t allow opening corrupted Outlook OST file data. In that case, when your Exchange Server is down, you cannot recreate your OST file to replace it with a corrupted one. That is the situation when manual OST file conversion becomes impossible.
  3. Orphaned Outlook OST files in Exchange Mailboxes can’t Recover:  OST files that are not connected to your Exchange server are called orphaned OST files. When Exchange crashes, the only source of the user’s mailbox data is an orphaned OST file. Shockingly, there is not any manual method that converts orphaned OST data files. OST file which is connected to your Exchange Server is only converted using manual methods.
  4. Needed Top-notch Technical Expertise: Manual methods are suitable for those users who are experienced in Outlook or those who have technical knowledge in data migration. We advise if you are a novice as per your technical skills, don’t try these methods to convert OST to PST. It may cause your OST file inaccessible for Outlook or maybe hardly corrupt.
