The .PST files are commonly used in storing the archived items where as the .OST files are used in storing the items in an offline mode. By transferring the files from the mail server to these .PST files, the mail users can free-up their mail server storage space and use the .PST files for offline mail access from another location. While the users can open and access the .PST file from other locations by using the network, this is not advised by Microsoft tech support as the files may get corrupt if used this way.
When we save our email messages, contact lists, notes and calendar entries, to name a few, on the HDD of our computer, the size of the PST file which stores these items increases and the large sized file occupies too much of our precious HDD space.
To minimize the space utilization, users often compact this file. Compaction normally results in a PST data loss and the users need to take help of PST recovery applications to recover such data losses. In this process, users commonly delete the unused data from the PST files and compact these files to reduce the PST file size. The compaction process helps in cleaning out the empty spaces in the file as there is a lack of better term in the said file. While the process of compaction gets carried out, there can be an application crash which results in the termination of the process and an error message flashes out which looks like “messaging interface unknown error messages”.
The Personal Storage Table files, which were not used by the compaction process, remain unaffected and there is no data loss but the files which were used in the process lose some of the data during application crash. One can recover the lost data from the corrupt PST file if a backup of the file has been maintained but those who have not maintained a backup need to use some effective PST file recovery software which helps in recovering and restoring the lost data.
