Lookup email ID in a column in a Excel Table

Posted on by Socrates

Hello

I'd like some help on how finish off a Flow I've started, please. I'm currently getting a list of emails that are sent from a certain email address:

That all works fine, but I'd like to lookup the Message ID of these emails in an Excel Table (Stored in OneDrive - table contains columns titled: SentDate, EmailID, Subject, Body Preview, To). If the message ID is there, then nothing happens, but if the message ID isn't present in the excel sheet, to add the relevant information in.

I can't quite get it to work. I only seem to be able to add all the emails in again, or get caught in a loop where it's adding every email, for every row.

Thanks

Hi there! So, it sounds like you're trying to sync your emails (in a sense) with a spreadsheet, right? The reason (I'm guessing) you get all the emails added in again is because as a condition checks each of the emails against your list, it will add it in if it doesn't find a match, right?

For example, if I have 10 emails in my inbox (wishful thinking) and the first 9 are already in the spreadsheet, it will look at email #1 in my inbox and compare that to row one in my spreadsheet...not a match? Add a row. Row two...not a match? add a row.

And so on.

There are a couple of ways around this:

Change your trigger so that the Flow is triggered when a new email comes in, it adds it to the spreadsheet. Then you won't have to check for duplicates.

Create a variable at the beginning, and then inside your Apply to Each loop (for matching against the Spreadsheet), update the variable with the email data, but only write it to the spreadsheet if you finish the loop without a match.

There are a few ways to get this done, but here's another thread of someone trying something similar.

Keep us posted.

Thanks @edgonzales that link did help. Having the variable as the true/false was the biggest breakthrough for me.

For anyone that may stumble on this in the future, my flow ended up looking like this. The first 'apply to each' I had to use the values from the email rather than the lookup table.
