Frequently Asked Questions

Commonly Asked User's Questions and Answers

How can I check whether my OST file is synchronized with Exchange Server or not ?

You can simply check for the synchronization of your OST file in the following steps:

  • Right click on the offline folder to view its properties.
  • Open Synchronization tab and read synchronization info.

If the “#items” value is same for server folder and Outlook offline folder, then your OST is synchronized with Exchange Server. Otherwise, if values do not correspond, your OST is not synchronized with the Exchange Server.

You should go for the following approaches to manually fix crashed Outlook account:

Approach 1: Permanently Kill Outlook Ongoing Processes

Firstly, kill all the running processes for Outlook application by the following steps:

  • Browse Task Manager by pressing CTRL+ ALT + Delete.
  • Click on “Processes” option
  • Choose all the running processes related to:”Outlook”, “communicator”, “Lync”, “ucmapi”
  • Click on End Task option to kill all Outlook processes.

Approach 2: Disable Cache Mode

The Exchange cached mode might be enabled on your system, which may have crashed the application. Disable the cached mode in following way:

  1. Exit Outlook application and open Control Panel.
  2. Browse Mail > Email Accounts > Email options.
  3. Select the account for which error is generated.
  4. Click on Change option to view settings.
  5. Unmark the Use Cached Exchanged Mode option.
  6. Click on Next and Finish to save the changes made.

Now, start Outlook application to access your account without any error.

The Offline OST file can be easily synchronized with server by making small changes in the settings. Once, the changes are made your OST will get automatically synchronized and will make changes to server on establishment of connection.

  • Under Outlook account, browse Tools > Options > Mail Setup
  • Click on Send/Receive option.
  • Check mark Send immediately when connected option.
  • Under Send/Receive dialog box, choose Perform an automatic send / receive.
  • Click on Save to make the changes made.

There are two main situations to create OST file:

  1. In latest MS Outlook editions if any user configure MS Outlook with IMAP protocol then it creates *.ost file to save data
  2. If MS Outlook configured with POP3 protocol (Post Office Protocol3) then it will create *.pst file to save data but if users connect POP3 configured MS Outlook with Exchange server then it creates extra *.ost file also.

Microsoft Outlook provides high level security for OST files because most of corporate users prefer it. But sometimes if MS Outlook got corrupted then OST files can’t be accessed again in Microsoft Outlook. A lot of users want to convert their important data from OST files to use it again in MS Outlook and other email clients so OST file conversion is important.
