When you start Microsoft Outlook or try to open a personal
folders (.pst) file or an offline folders (.ost) file, you may receive the
following error message:
Errors have been detected in
the file <file_path>. Quit all mail-enabled applications, and then use the Inbox
is the path to the .pst file.
If you run the Inbox
Repair Tool (Scanpst.exe), the file does not resolve the problem.
This problem occurs because the .pst and the .ost files
have a 2 gigabyte (GB) size limitation, and the error message occurs when it is
exceeded. The Inbox Repair Tool cannot correct this problem.
To resolve this problem, download the tool from the
following Microsoft Download Center link:NOTE
: Use the tool to create a truncated copy of the .pst file. The
copy that is left after the tool completes does not have all the original data
because the tool cuts a user defined amount of data from the file.
Recovery Limitations of the 2 GB Truncation Utility:
- You must have 2 GB of free hard disk space (to make a copy
of the .pst file).
- The utility truncates the .pst file to under 2 GB. To have
enough working space, truncate the file between 20 to 25 megabytes (MB) less
than the 2 GB limit. The truncated data is removed from the new copy, which
means some messages are missing from the recovered copy.
You can use this process to attempt to recover the data, but is
not 100 percent successful. If this tool does work, it does not recover all of
the data (the truncated data is missing).
Use the following steps to recover the data:
- Download the tool from the following Microsoft Download
- Extract the 2gb152.exe file to an empty folder. You should see the following five files:
- Start the Pst2gb.exe program.
- Click Browse to select the oversized .pst file, and then click Open.
- Click Create, select the name and location of the truncated data file that you
want to create, and then click Save.
- Type in the amount of the data that you want to truncate in
the .pst file. There is not a correct amount that you use. You can receive the
best results if you use 20 to 25 MB, but you may have to truncate more or less.
For example, if you truncate 25 MB of data and the process works, repeat the
process and truncate the original oversize .pst file by only 15 MB. If that
works, then try the process with 5 MB. If 25 MB does not work, repeat the
process and truncate the original .pst by 35 MB. If the process does not work,
increase the amount until the process is successful.
- Run the Inbox Repair Tool (the Scanpst.exe file) on the
smaller .pst file.
- Open the repaired .pst file in Outlook.
- (This step is recommended but the step is optional) If the
file opens, right-click the root folder of the .pst, click Properties, and then click Compact Now to start the compression. For a file of this size, the
compression may take approximately 4-8 hours.
- If the file does not open, discard the truncated .pst file,
and repeat the process with the original .pst file. Truncate more data than in
the first attempt, and try the process again.
- Install the following update or hotfix depending on the
version of Outlook that you have.
These updates prevent Outlook from allowing the
.pst file to exceed the 2 GB maximum size. Use one of the following methods to
manage the size of the .pst files:
- Use more than one .pst file.
- Use the archive feature.
- Save attachments to a file system folder and delete
them from messages.
