MSG Editor

Edit an Outlook MSG email’s body as email‑client HTML using a table‑based layout with inline styles. You can modify the sender, recipients, subject, attachments, and the HTML body, then download the updated Unicode .msg file. Only HTTPS image links are kept; other image sources are removed.

Recipients and Subject

The editor displays the From, To, Cc, Bcc and Subject fields from the opened MSG and lets the visitor change any of them. Cc and Bcc rows are hidden until the corresponding button is clicked, but they appear automatically if the original message already contains those recipients.

Address entries accept the standard “name@domain.tld” format or a display name with angle brackets, and multiple addresses can be separated by commas or semicolons. Validation runs on save, highlighting any invalid address with an error message and focusing the problematic field.

Only one From address is allowed; leaving the field empty results in a saved MSG without a sender. The subject accepts up to 998 characters and is saved exactly as entered.

Body Editing

The message body is edited in a block‑based editor that outputs email‑client‑compatible HTML using a table‑based layout with inline styles. Visitors can add text, headings, lists, quotes, buttons, dividers, columns, and other common email blocks, applying formatting and links via an on‑selection toolbar.

When an existing MSG is opened, any rich‑text or plain‑text body is converted to this HTML format for editing; the conversion is indicated by a dismissible notice. The edited body replaces the original content in the saved Unicode MSG file.

Images by Link

Only images referenced by HTTPS URLs can be inserted. The editor provides an image block where the visitor supplies the link; dropped or pasted image files are not accepted, and a notice advises uploading the image elsewhere first.

Embedded pictures, HTTP links, and data‑URI images that exist in the original MSG are removed during opening and are not re‑included when the message is saved. After saving, the tool reports how many images were removed, while HTTPS‑linked images remain as external references.

Attachments

All regular attachments from the opened MSG are listed with file name and size, and each can be removed individually. Attachments without a name are shown as “attachment‑1”, “attachment‑2”, etc., based on their order.

Visitors may add new files of any type, attach several at once, and remove any newly added attachments before saving. All kept attachments are stored unchanged in the resulting Unicode MSG file.

Limits and scope

File size

The editor opens and saves MSG files within the size limits set by the visitor’s account tier (anonymous, free Aspose, Premium, or custom business limits).

Retention

Opened files and generated download links are kept for 24 hours before automatic removal.
