I've created a Flow in which it uses the For a selected file trigger on a SharePoint Document Library.

It then tries to extract the email address of the user who triggered the Flow, however, the email address returned is encrypted!

Can anyone else replicate this?

Extract the email address of the user who triggered the Flow...email address returned is encrypted!

Thank you, this gave me the tip to look at decoding functions. The example you linked to is relevant when you're dealing with attachments. However, to decode the email address of the user who triggered a flow, you can do it slightly different:
decodeBase64(triggerOutputs()['headers']['x-ms-user-email-encoded'])
Hope this helps someone else in the future.

I think I've found a work around as of 2/25/21:
How to avoid corrupt email attachment in Power Automate (tomriha.com)
I believe the formula snippet could be applied to other parts of the email as well
format: base64ToBinary([Attachments Content]) note: [Attachments Content] is a dynamic content when using in a flow, it could look like this: base64ToBinary(items('Apply_to_each')?['contentBytes'])

I am currently experiencing this issue since yesterday, 10/29/2020. Anyone else having this issue?

Update: I was able to create a new flow as a work around for this issue. It is unfortunate to have to transfer all my actions to the new flow to resolve this issue.

It appears it's not fixed. Mine just started having this issue last week (10/11/2019)

Any suggestions.

What the heck?!?! It's now working again.

Someone has been tweaking the encoding behind the scenes!

OK - just found out that this is Base64 encoding:

Anyone know how to decode from base64 back into plain text?
