Flow with Send an email (V2) not working with a certain email account

[Anonymous]

Hi Power Automate Community!

I was updating a Flow that I once posted here looking for help.

TL;DR: I wasn't able to use the Outlook connector because I didn't have access to a service account, but now I do. However, when I try to connect the Send an email (V2) connector to the new account it gives me the following error:

InvalidTemplate. Unable to process template language expressions in action 'Send_an_email_(V2)' inputs at line '1' and column '2677': 'The template language expression 'json(decodeBase64(triggerOutputs().headers['X-MS-APIM-Tokens']))['$connections']['shared_office365_1']['connectionId']' cannot be evaluated because property 'shared_office365_1' doesn't exist, available properties are 'shared_onedriveforbusiness, shared_commondataservice, shared_office365, shared_excelonlinebusiness_1'. Please see https://aka.ms/logicexpressions for usage details.'.

If I change the connection to my account instead of the service account it works again properly. I've seen other similar posts which suggests deleting it and building it again, but it didn't work for me. It just doesn't work with the account that needs to work with.

Hope you can help me and thanks in advance.

Hey @Anonymous 

Any chance this flow is being triggered from a PowerApps control or any external such control? If so, I would recommend to delete the flow from that control and add it back again. 

Hope this Helps!

Hi @Anonymous 

I think this is an issue with permissions. Probably the new permissions to this account haven't propagated yet. Your flow is correct since you can use your account, and all works fine. 

Flow sometimes sticks too long with connections, even if they change. Try the following. Export your Flow and re-import it again. Then Flow will be forced to fetch the new connection, and maybe this will solve your issue.

If you're not familiar with import and export, here's how to do it.

Hi @yashag2255,

It is triggered from a Power Apps control. However, if I delete it I am no longer able to see it from Power Apps (Action > Power Automate) as the following image shows:

Looks like you haven't created any flows yet. To get started, select 'Create new flow' below.

I just solved it by recreating the flow from INSIDE the Power App (Action > Power Automate > Create New). Not quite the approach you would expect to be honest 😞
