In most cases, it is due to the oversized data file, which results in PST file corruption. This issue mainly depends on the version of Outlook a user is using. However, Outlook 2003 and below versions create ANSI type of PST files with a 2 GB storage limit. In the above versions, the storage space varies from 20 GB to 50 GB and is called a UNICODE type of PST file. However, the archive is also a PST file, which represents the user profile.

Thus, this oversized PST file is applicable to the archive.pst file also. When this situation occurs, a user receives an error message like archive.pst has reached the maximum size.
