Anti-Virus Software Creating Bad PST Issues

Microsoft Office Outlook uses personal folder (PST file) to store local copies of all email messages and other Outlook items. The file is loaded each time when you start Outlook. If you are using an anti-virus software to scan the file, the odds are that it might prevent you to open PST. It mainly occurs due to certain incompatibilities issues. Also, if the file is damaged or infected from virus, you will get similar symptoms and errors. Such situations cause data loss and require you to recover from the most recent PST backup you have. At times, when no file backup is available or the available backup is not valid enough that you could restore lost information from it, you should use advanced Outlook PST Repair tools that can effectively repair and restore a damaged PST file.

As an example, when you start Microsoft Office Outlook, you get the similar error message displaying on screen:

"Your Anti-Virus software has blocked the file you were trying to open."

You should ensure your Anti-Virus software is fully up to date and try opening the file again. It is important to note that the blocked file may also contain a virus which your Anti-Virus software has not been able to remove. In this case you should treat the file with caution.”

Application crashes after you receive this error message.

Cause

You encounter such errors if one of the following conditions exists:

(1) The antivirus software you are using is incompatible with Microsoft Office Outlook. It might also occur if you are using an outdated anti-virus software and its signature files are damaged.

(2) You are trying to open a virus infected PST and the anti-virus software in use cannot remove that virus.

(3) PST file is damaged.

Solution

The solution depends on the root of the issue. Try resolving the aforementioned issue using these methods:

(1) To update your anti virus software from the recent updates, you can download the updated virus signature file that vendors of anti virus software provide periodically. This is done on the basis of new virus created.

(2) If you don’t doubt that the anti virus software or its signature files is the issue, the file might be infected from virus that your anti virus software is unable to remove. Such files should be deleted as soon as possible and restored from backup. Alternatively (when no valid PST file backup is available), you can use commercial tools that could Repair Outlook PST and restore it at a safe location.

(3) If PST file is corrupted, no anti-virus software and Microsoft Office can handle such file. Such PST file needs to be repaired. To perform PST Repair, you can use these methods:

In Outlook 2007, the same tool is found at this location:

:\Program Files\Microsoft Office\Office12

Here, disk drive represents the primary drive of your system, usually C.

How to Solve PST Hotsync Issues?

HotSync is defined as the method of linking a computer system and a Palm handheld device to allow a sophisticated synchronization between the two systems. You require a HotSync cable or a wireless connection that could setup a communication between these devices. When you setup Outlook to hotsync with your Palm device, all PST contents, which include emails, tasks, appointments etc., can be synchronized. Since the operation affects the PST data directly, odds are that the synchronization process may fail if the file is corrupt. You can repair a corrupted PST using Outlook Inbox Repair Tool (Scanpst.exe). But if this doesn't work, such situations create unavoidable situations of using a backup. If this fails too, you should use a PST Repair application.

To understand such problems, consider a practical instance when you try to synchronize Outlook data with your handheld device. You choose Outlook as the translator and click to synchronize an Outlook item, for example notes, contacts etc. The operation may fail with the below error on the screen:

“The file or database name associated with MS Outlook is missing, invalid, or points to a file of zero length. Use the browse button to locate the file or database”

Cause

Solution

To solve the discussed issue, you should apply these methods:

(1) You should delete and recreate the corrupted MAPI profile.

(2) For retrieving data from corrupted PST, you should first run Inbox Repair Tool (Scanpst.exe). The file can be located using Windows Search option while ensuring that the view of hidden files and folders is enabled. If Scanpst fails to repair, consider the latest backup to restore.
