I’m trying to create a backup of my outlook.pst file at some other folder but receiving 0x80070021 error. I also tried copying it to some other location but still receiving the same error. I say that ‘File can’t be copied; some other process has locked a portion of the file.’ How can I solve this problem?
This error can occur due to hardware failure, failure of data storage device, network device failure, or power failure. You can use this method to fix the error-
If the above-mentioned steps are not helpful to you, try these steps-
If you receive error code “0x80070021” in Microsoft Office Outlook, the usual cause is the Microsoft Office Communicator because it is frequently tightly connected with Microsoft Office Outlook. Try closing Microsoft Office Communicator then see if it works. If this doesn’t work, try this one instead. In Microsoft Office Outlook, click “File” then select “Outlook Options” at the bottom. In “Options” window, select “Add-Ins” on the left pane.
On the right, at the bottom in “Manage”, select “COM Add-ins” then click “Go”. Now, in “COM Add-Ins” dialog, select “Search Email Indexer” if you see it then click “Remove”. Click “OK” then restart Microsoft Office Outlook. See if this works. If you don’t see this item listed, check for “Windows Email Receiver Index” instead and remove it.
If you want to create a backup of all your messages or a particular message folder, you can export the items to a PST file (.pst) which you can use later to restore as required by importing. To back up your email, in Microsoft Office Outlook, click “File”, “Open & Export” then select “Import/Export”. On the next screen, select “Export to a file” then click “Next”.
In “Export to a File” dialog, select “Outlook Data File (.pst)” then click “Next”. On the next screen, select the mail folder or folders you want to back up then click “Next”. On the next screen, click “Browse” then navigate to the folder where you want to save the file. Enter a name for the backup file then click “Finish”.
Note: if you want to protect the file from being accessed by anyone, enter and confirm a password then click “OK”.
