  2. On very start of your Microsoft Outlook application, you get this error:
    “Cannot open your default email folders. The file xxxx.ost is not an offline folder file”xxx.ost is the OST file name with the extension.
  3. If we talk about reasons of this error, it could be damaged OST file (due to virus infection, sudden termination of Outlook-Exchange synchronization process, Oversized OST, etc.)
    Also, other reason could be when Outlook fails to synchronize with Exchange mailbox related with OST file.
    Sometimes, when you use Microsoft Outlook to synchronize or open .ost file, you found this error:
    Unable to expand the folder. The set of folders could not be opened. Errors could have been detected in the file xxxx.ost. Quit all mail-enabled applications, and then use the Inbox Repair Tool
    Outlook fails to synchronize if the .ost file is corrupted or gets orphaned.
  4. If you are able to open .ost file folders but cannot synchronize them with Exchange Server. In this case, user receives different synchronization error messages as synchronization log in Deleted folder.
    Common reason behind this error is that .ost file is damage; email messages are corrupted and restrict the synchronization process.
  5. One .ost file error is getting differences in messages while switching between offline and online mode.
    Corruption in .ost file is again the reason for this error.
  6. If you not able to find some mailbox items (emails or contacts) as they are missing during the offline mode, then again possibility is there that your .ost file has corruptions.
