How to Fix the Error “Unable to Expand the Folder” in MS Outlook?

MS Outlook creates a mailbox which holds all the attachments and emails in various folders. To store mailbox data there are two types of files used on your local drive – Offline Storage Table (OST) file and other is Personal Storage Table (PST) file. You should use OST file to configure Outlook in offline mode. In OST file, all the offline work is store and synced with Exchange Server when it is connected to the internet.

Sometimes, it shows the following synchronization error –

 

Unable to expand the folder. There are errors in xxxx.ost file. The folders couldn’t be opened. Quit all the mailbox applications and use Inbox Repair tool.

 

If you get this type of error, there must be a problem in your OST file and it couldn’t get synced properly with Exchange Server. Some of the common reasons of OST file corruption are –

  • Exchange Server crash
  • Virus attack in OST file
  • Exchange Server Database Corruption
  • Mailbox deleted from Exchange Server

 

How to Fix?

As discussed in the error message, quit all the applications which might be using OST file.

  • Retrieve the repaired items.
  • Repair OST file by running scanpst.exe (Inbox Repair Tool).
  • Find OST file
