Hello,

I have a flow that monitors an email box folder for flagged emails. It copies the subject to a SharePoint list Single lIne of text column. The body of the email goes into a multiline of text column with rich text. Emails with images embedded in the email body cause the workflow to fail. How can I strip the image out of the body before copying the text to the SharePoint list?

Hi FW-07051511-0 ,

Thank you for choosing Microsoft Community.

Use a Compose action with a regex replace to remove all <img> tags from the HTML body before saving it to SharePoint.

I hope this helps resolve the issue! If you need more specific guidance, feel free to ask.

When the email body contains embedded images (<img> tags, inline CID images, base64 images, signatures, etc.). SharePoint multiline rich text fields often reject or choke on very large HTML generated by Outlook.

Let me give you three approaches that can work well:

Option 1: Removing all HTML and store plain text, If you don't need formatting, insert an Html to text action before creating the SharePoint item.
When a new email arrives (Trigger), Html to text Content: Body (Action) + Create item Body column = Output of Html to text (Action)

This approach strips images, HTML, formatting, and leaves only text.

Option 2: Remove only IMG tags and keep formatting

If you want to preserve HTML formatting but remove embedded images, use a Compose action with a regular expression replacement.
with a simple string replacement if you know the pattern, if you have something like this: <img src="cid:image001.png@01DA..." />
you could remove these with successive replace() expressions, like this replace( outputs('Get_email')?['body/body'], '<img', '<removedimg' )

This is not ideal because the tag still remains.

Option 3 (My Favorite) : If preserving formatting is important, use Unique Body instead of Body, and write that to the SharePoint rich text field

substring( outputs('Get_email_(V3)')?['body/body'], 0, 60000 )
If you can share the exact error message from the failed run and whether you're using When a new email arrives (V3), When an email is flagged, or another Outlook trigger.

Let me know if this can help you

Hi FW-07051511-0 ,

You can disable the image with this syntax in Compose action:

replace(replace(triggerOutputs()?['body/body'], '<img', '')
This syntax helps to comments out the <img> tags, disabling images in the HTML.

I am sure some clues I tried to give. If these clues help to resolve the issue brought you by here, please don't forget to check the box Does this answer your question? At the same time, I am pretty sure you have liked the response!

For a mailbox-monitoring flow that archives emails into SharePoint:

Get Email (V3)

HTML to Text

Create/Update SharePoint Item

Subject = Email Subject

Body = HTML to Text output

This removes all embedded images, signatures, and unsupported HTML while preserving the actual email content and is generally the most robust approach.
