Hi, it seems that you are encountering some severe Outlook problem due to damaged Network PST files. It is one of the common issues that has been commonly encountered and displayed as:
“The file [drive]:\archive.pst is not a personal Folder File”
Such messages clearly indicate that Outlook is unable to locate or access PST files present on the network server. That is why Outlook users are always advised to split the oversized PST files into two or more smaller files. Actually there can be various contributing factors that might impair or damage Network PST file. Some of the important ones can be highlighted as:
Corruption of the PST database.
Unsuitable structure of the database.
Restricted access to the file.
Speed of the internet connection also does matter a lot. Outlook users will not be able to access and save the PST files settings and may encounter the following error messages. It may result in loss of stored data. Thus you may use Scanpst.exe utility or inbox repair tool to scan and access the PST files. In case, you are unable to locate or resolve the issues with Scanpst.exe utility, try third party Outlook PST repair software. It is the best tool that is designed to repair or fix network PST file error and to access the data once again.
