Q. What to do when Outlook Express gets crash or corrupted due to any fault like corrupted Folder.dbx file?
Ans: Follow the steps to avoid the corruption in dbx files:
Outlook 2002 and earlier use ANSI format for PST files. This format has a file size limit of 2GB.
Exceeding the file size limit prompt error message ".pst has reached maximum size limit," and could become corrupted. In Outlook 2003 and later versions, PST files are created in the Unicode format and have a default maximum size of 20 GB.
