Let’s look at a few common reasons behind ‘Outlook OST Synchronization Error’, and their solutions:

     1.     Network connectivity issues

Outlook synchronizes OST file with the Exchange mailbox, when the connection to the server is available. However, limited or unreliable connectivity of Outlook with Exchange Server can result in synchronization error. Such a situation even makes the OST files inaccessible.

Solution: Check all your network connections for proper functioning, and then try resynchronizing the Offline folders

     2.     Synchronization is interrupted  

You may get the ‘Error 8004011D-526-80040115-0’ when the synchronization process of Outlook and Exchange server is interrupted due to:
  • Sudden power failure
  • Network problem


Solution: Wait till the Exchange server comes back online and synchronize your OST file again.

     3.     OST file corruption

The ‘OST Synchronization Error’ is also generated when the OST file you are trying to synchronize with the Exchange server mailbox is found to be corrupt.

Note: You can try restoring the OST file data from backup. This method, however, won’t work in case you haven’t created a backup prior to the synchronization process. If so, you’ll need to repair the corrupt OST file.

Solution: OST file can be repaired by using the following methods:

Method 1 – Leveraging the Microsoft inbuilt Utility
Microsoft recommends using its built-in utility, the Inbox Repair Tool (also called scanpst.exe), to diagnose and repair errors in Outlook data files. The steps for using the Inbox Repair Tool to repair Outlook data files.

NOTE: While this method is easy to understand and implement, it has some limitations, the most important being its inability to fix severely damaged or corrupted OST file. Moreover, the ‘Inbox Repair Tool’ cannot fix oversized OST files (exceeding 2 GB).

Method 2 – Using a ‘Converter for OST’ Software
The best alternative to scanpst.exe utility is a software-based solution that can help repair and restore corrupt/inaccessible OST files.

Use Stellar Converter for OST, as the software reduces the data loss risk by converting all the OST file components to an Outlook compatible (PST) format.

A few other reasons that makesStellar Converter for OSTsoftware worth-trying are:
  • Converts inaccessible or encrypted OST files, into PST files
  • Allows converting OST files into PST files without worrying about file-size limitation
  • The extracted data (comprising emails, calendars, and deleted items) in PST file is available as “Preview” for user verification
  • The software makes it easy to import and sync PST file into Outlook
  • The software provides free OST to PST conversion for first 20 emails per folder and much more.


A Few other recommendations

  • Check whether the offline folders are synchronized correctly or not
  • Try disabling the anti-virus software (if any) 

Summing Up!
As you can never predict when you may encounter server downtime, network or file corruption issues, it becomes imperative that you have synchronized your Offline data file (.ost file) with Exchange server mailbox. However, synchronization at times can go wrong, resulting in ‘Outlook OST Synchronization error 8004011D-526-80040115-0’.

The safest answer to this problem is third-party OST to PST converter. These tools easily repair your damaged OST file and recover all data quickly. After that user can easily export recovered data into PST file format. Here I want to suggest Syscurve OST Converter Tool.
