How it works: technology, search and security

Technology

Mail Attachment Downloader is a standalone local application: it talks directly to your mail server and processes everything on your PC, with no cloud intermediaries. It works with Gmail, Outlook.com, Yahoo Mail (requires an app password) and any other IMAP mail server, and with Microsoft 365/Exchange via Graph or EWS. Older POP3 mail servers are supported too.

Gmail attachment downloader

Choose Gmail as the server type and sign in with Google in your web browser: the program never sees your password and no app password is needed. It works with personal Gmail and Google Workspace accounts, downloads from your Inbox or the labels you pick, and if Gmail's daily download limit is reached it stops and continues where it left off on the next run. You only need IMAP turned on in Gmail. Gmail setup guide

Outlook attachment downloader

Download attachments from Outlook.com, Hotmail and Live accounts, or from Microsoft 365 and Exchange Online work or school mailboxes, including shared mailboxes. You sign in with Microsoft in your web browser, and the Outlook desktop app doesn't need to be installed or open. Outlook and Microsoft 365 setup guide

Search

Search filters make it easy to download just the attachments you need: search the mail headers like from and to, or even the body, filter by file type like documents or images, or by email size. More info

Will this affect my email?

No. Mail Attachment Downloader leaves all your mail on your server as is and does not mark it as read. It will not interfere with any other programs you use today to download your mail.

Security and privacy

Your downloads are private. Emails and attachments go straight from your mail server to your PC; no third-party service or cloud provider is involved. Mail Attachment Downloader is CASA Tier-2 certified. Connections default to TLS with OAuth support for multi-factor authentication. Passwords and tokens are stored securely with least-privilege access (e.g. Windows DPAPI) and are never logged. Some providers, such as Yahoo, need an app password. The PRO editions can also sign in through your organization's own Microsoft 365 or Google app registration.

FAQs

Frequently Asked Questions

Why does it download all my mail the first time I run it?

The program identifies new mail based on when it last successfully downloaded attachments.

So when you run it for the first time, since no attachments have been downloaded yet, it will download all mail attachments in your email inbox after which it will only scan for mail attachments that arrive from thereon (including read and unread mail).

The default setting will only download messages since last download including unread mails that have not been downloaded by the program. IMPORTANT: If you switch this setting to All mail at any time, any state will be lost and the next time you select messages since last download it will download from the start again. To avoid this, select a date filter (see FAQ below titled "How do I download from a given date?").

Subsequent runs by clicking the 'Connect And Download' button will download remaining mail attachments that have not been downloaded yet until it has downloaded all attachments till the present day.

Can I download all attachments from Gmail or Outlook at once?

Yes. The first run downloads the attachments from all the mail in your Gmail or Outlook inbox, or from the Gmail labels and Outlook folders you select (choose Selected Folders in the Folders and files tab). To start from a given date instead, set a start date as described below. Large Gmail mailboxes can reach Gmail's daily download limit: the program stops, keeps its place and continues on the next run.

How do I download from a given date?

If you don't want to wait to download all email attachments the first time, set the 'start date' from which you want to download your attachments in the Search tab. Leave the 'end date' unchecked to indicate that there is no end date.

How do I re-download the same attachments?

If you you want to re-download the same attachments that the program had already downloaded in the past, choose Search -> Check In -> All mail. You may also want to check the Inline Content checkbox if you want to download attachments that are inlined. For certain types of mail servers this will be checked by default.

Do my emails go through a third-party or cloud service?

No. Mail Attachment Downloader runs on your PC and connects directly to your mail server, so your emails and attachments download straight to your drive. No third-party service or cloud provider is involved, and your mail stays on your server as it was.
