File size is crucial for an OST file. If the file size of the OST file exceeds the suggested size of 2 GB then problems start occurring. However, you are not limited to grow your OST file size, but as the best practice and problem free use of Microsoft Outlook, it is always suggested to keep the OST file limited to 2GB or less. You should even avoid getting the size of 2GB because reaching 2GB or more may cause the below-listed issues:
And, in case the file size has crossed the limit of 2GB, you will get the below-listed error message when you start MS Outlook:
Errors have been detected in the file . Quit all mail-enabled applications, and then use Inbox Repair Tool.
What does this error message say? This error message says that your OST file has crossed the limit of 2GB, and you should crop it to reduce its size.
You can crop OST file by using the OST Crop Tool. This tool is also called 2GB truncation tool that helps you to reduce the size of OST file. In order to use this tool, you should meet the below-listed requirements.
Perform the below steps to use OST Crop Tool:
Perform the below steps to use scanost.exe file:
If the file does not open then it means the truncation was not successful. In this case, delete the truncated file, and then repeat the truncation process on the original file once again. This time you should increase the Truncate Data amount for successful results. Once you have truncated the file once again, browse it in the scanost.exe. It should open now. Once the file is opened in scanost.exe, complete the process of scanost.exe
Note: you will have to repeat the truncation process and scanost.exe process unless you are successful in reducing the size of OST file.
This is how you can crop OST file and reduce its limit to avoid related problems. While the problem listed above may solve the issue, you have to mind it that this process may be lengthy and time-consuming, as you may need to repeat the process several times.
If you want to save your time, then you are suggested to use an OST recovery tool. With the help of this tool, you can fix all the issues of the OST file and save it in small chunks without wasting your time.
