I need remove a caution message from an email when an user replies to the sent mail. This is not the case with all the user, only limited to few customers. Kindly help me to remove the message I don't want it to be captured.

And the thing is the caution message has an hyper link in it as encircled in the below image.

Hi @ganeshnr523 


Could you share how the same message looks like when viewed in html format when flow is ran from power automate ?

Hi @Nived_Nambiar 

I'm not able post it. It's getting removed I guess for some reason.

Is there any way you can help

Hi @ganeshnr523 


forget to ask one thing, does this caution text is fixed always ?

Hi @Nived_Nambiar 


It's not fixed always, it's configured differently for different users. But the color is red for all of the message.

Hi @ganeshnr523 


Just give a try this with this 


Step 1: trigger to receieve email 




Step2: Compose action to retrive caution message to end from email body




expression used: 

slice(triggerOutputs()?['body/body'],indexOf(triggerOutputs()?['body/body'],'span style="font-family:Calibri,sans-serif; margin:0px; background:yellow; color:red">'))
Step 3: use compose action to slice the result from 2nd compose step to retrive only caution message


expression: slice(outputs('Compose'),0,add(indexOf(outputs('Compose'),'<br>'),1))


Step 4: Use replace action to replace the text obtained from step 3 compose action in email body using compose action



expression: replace(triggerOutputs()?['body/body'],outputs('Compose_2'),'')


Step 5: use html to text action to convert html to plain text (using output from step 4 )





Result was like below


Input email body




Output email body



Hi ,

This is a test mail for the purpose of testing a flow. Kindly ignore it.



Hope it helps !

Hi @Nived_Nambiar 


I tried to test it, but getting the following




This is what I did from my end.




Expression in compose 2 - 

slice(outputs('Html_to_text')?['body'],indexOf(outputs('Html_to_text')?['body'],'span style="font-family:Calibri,sans-serif; margin:0px; background:yellow; color:red">'))
compose 3 -

Hi @ganeshnr523 


I would suggest two things


1. First try to do caution part seperate, and see if it works


2. The caution part should be placed before signature removal part as caution text should be removed with help of html only, once caution is removed, then we can send the updated html (with no caution text) to signature removing part, where operation is done via first converting html to plain text if i am right 🙂
