Google Takeout is a free service that allows Google account users to export and save a copy of emails and other account data on their devices in a .zip file (for Windows or Mac) or .tgz (for Linux). Once this compressed file is extracted, a folder named "Takeout" is created – containing several sub-folders, such as Mail, Drive, etc.
When Gmail mailbox data is exported via this utility, it gives users two options: to export all mailbox labels (folders) or select individual labels (specific mailbox folders). Former creates a single MBOX file – "All Mail Including Spam and Trash.mbox". The latter option saves the selected labels as separate .mbox files, for eg - Inbox.mbox, Sent.mbox, Trash.mbox, Spam.mbox, etc.
If you try to open a Google Takeout MBOX file in Outlook, you won't be able to do so directly. This is because, as per Microsoft, Outlook desktop client doesn't support the .mbox file format – it supports PST format. Hence, you'd need to convert the MBOX file first. Let’s read further to see how this is done.
