Saving All Messages to the Hard Drive Using VBA

Use this code to save messages with the date in the filename, retaining the Outlook file structure.

To save selected messages as PDF files, see Save Outlook email as a PDF

This code sample will save all messages in a specific Outlook folder (and any subfolders of the selected folder) in a folder you select on the hard drive. The messages will be in a subfolder of the selected folder, where the subfolder is named for the Outlook folder you selected.

Note: if you select a subfolder of a top-level folder, for example, a subfolder of the Inbox, folder named Inbox needs to exist in path on the hard drive.

The filename format is yyyymmdd_hhmm_subject.msg, as in:

20100422_0319_Inquiry.msg

The filename is set using this code:

StrFile = StrSaveFolder & StrReceived & "_" & StrName & ".msg"

Filenames are limited to 256 characters in length, with the subject trimmed if its too long.

Note that it can take some time to run if the folder contains a lot of messages. Allow about 2 seconds per message, or about 15 minutes for 400 messages.
