For example, suppose you try to import an Outlook PST. At this point, you may receive an error, such as mentioned below:
"This Personal Folders file (.pst) is already in use in the current profile."
The PST import process fails with no results.
Some of the possible reasons causing this behavior are as listed below:
1-You are trying to import a PST that is already being used by the local Outlook profile.
2-The current Outlook profile PST and the file being imported have same name.
3-PST is set to read-only attribute.
4-You are attempting to import a corrupt PST.
Based on the root cause of the given problem, you are recommended to apply the following measures:
1-Make sure that the PST being imported is different from which is in use
2-Rename the PST and try to import it again
3-Right-click the file to view its properties. Clear the read-only check box. If the file is stored on a CD or DVD, you first need to save it on the hard drive
4-Repair the corrupt PST using Outlook Inbox Repair Tool (Scanpst.exe)
