Match and Extract String from List using Power Query

[shocktech]

I am trying to extract the Primary SMTP address fomr the proxyAddress attibute in ADDS. When expanded the proxyAddress attribute is a list. An Exmple of the onctent might be as follows:

smtp: [email protected]
SMTP: [email protected]
X500:/o=VHI/ou=First Administrative Group/cn=Recipients/cn=bloggs_j
x500:/o=ExchangeLabs/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=744b0ca795fa4892a71b247bcd3009f3-bloggs_j

The primary SMTP address is the one that begins with uppercase SMTP. As such, I need to match that list item and return it as a sring. I can't seem to figure this out using the List.Select type funtions. Any assitance would be greatly appricated.

Hi @shocktech 

Do you mean each row in the text you show is an element in a list? And by list you refer to a PQ list, for example {1, 2, 3, 4} ?

Place the following M code in a blank query to see the steps of a potential solution:

let
    Source = { "smtp: [email protected]",
        "SMTP: [email protected]",
        "X500:/o=VHI/ou=First Administrative Group/cn=Recipients/cn=bloggs_j",
        "x500:/o=ExchangeLabs/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=744b0ca795fa4892a71b247bcd3009f3-bloggs_j"},

    findSMTP_ = List.Select(Source, each Text.Contains(_, "SMTP")),
    res_ = Text.Combine(List.Transform(findSMTP_, each Text.Trim(Text.AfterDelimiter(_, "SMTP:"))), ", ")  
in
    res_

Yes indeed. I am using PowerQuery in Excel 365 Desktop app. I should have clarified this. Apologies.
