Two Ways to Reduce Outlook OST file Size

You may come across gradually slow operations or freezes with the Microsoft Outlook. If you know, this could be as a result of the increased size of the OST file (Outlook Data File). As the size of the OST files exceeds the specified limit it tends to show some or the other issues with it. Other chances include-

  • Synchronization issues with MS Exchange Server
  • Unable to open or load the OST file
  • Error pop ups during synchronization process
  • Not able to add new data file to OST

To overcome such OST issues, users implement a method to delete an OST file. Deletion of such oversized OST file will not be removed but instead, it will be moved to another folder. Ultimately the size of the Outlook Trash folder increases and hence the size of OST remains the same. Now the thing that you can do is, reduce the size of your oversized OST file. Basically, there are two ways to reduce the Outlook’s OST file size – manually or with a third-party utility.

  1. Manual Method

Before you proceed with this method, it is better that you backup your files. It is because if something goes wrong in-between you will not have to worry about your files. In case, if you don’t have a backup then go through this blog to recover deleted emails in Outlook with simple clicks.

  • Rename Offline OST files: If you find issues in the opening, sending or receiving Outlook emails then go with renaming the OST file. After renaming, restart the MS Outlook application on your computer.
  • Try Safe Mode: Another way to deal with Outlook errors is to run the MS Outlook application installed in your system in a safe mode.
  • Archive the OST File: When there is no enough space on the server you can go ahead to archive it in the offline Exchange Server. This, in turn, helps in clearing the space.
  • Disable add-ons: Some installed add-ons can affect the working of MS Outlook program. Henceforth, check if the Outlook functions properly by disabling all the installed add-ons on your Outlook profile
  1. Use Third Party Programs

If you are not comfortable with manual approach then you can seek the help from third-party utilities. There are many applications available over the internet that possibly reduces the OST size by splitting it up.
