Get email "from" when alias was used.

[CoupalM]

Hi,

I have a shared mailbox with multiple alias. When someone send an e-mail to the shared mailbox using one of the alias, I would like to know which alias was used to send email. My flow receive the email but return the primary shared mailbox address as the "To" and not the alias used by the sender. Is there a way to get this info? 

Thanks.

Ok, I found 2 solutions. 1 is to use the "export mail content activity" where I can find the "To: [alias]". However, the syntax is not always consistent from different mail providers so can be hard to parse correctly.

2. I decided to create a distribution list for each of my alias and put the shared mailbox address in them. Now if someone send an email to the distribution list address, the new mail action will return the distribution list email address instead of the shared mailbox address.

Hi @CoupalM, you wrote:

The syntax of what? The SMTP address syntax is quite "consistent".

[CoupalM]

There are just some small differences, nothing major but need to take into account when parsing the email address.

Here is what the export activity is returning from an outlook/exchange message:

\r\nTo: \"alias@contoso.com\" <alias@contoso.com>\r\n

Here is what the export activity is returning from a GMail message
\r\nTo: alias@contoso.com\r\n

You can always find last @ in the string and after that detect start and end of SMTP address.

It's been a while but I was wondering if you would provide more details/clariifications.    

1. Are you referring to the Export mail (exchange connector) action?  If so, I seem to be getting Forbidden when attempting to use that action, despite being a member of the group that owns the mailbox, did you have to make any permissions changes to group/exchange to get that to work?

2. What is the mail ID that you're using when fetching the mail?  ConversationID, ThreadID, PostID?

Hi @PaulCONeil, 

could you please show your flow with "forbidden" error? 

[PaulCONeil]

See attached.  The I've tried to use the Conversation ID, Thread ID, and Thread Post ID and am getting the same result (Forbidden/group shard).   All I'm trying to do is determine the "To" address (would be an alias for the group) that the email is coming in with because I wanted to have the flow branch depending on which email address was used.

[VictorIvanidze]

It looks you are trying to retrieve something from a group mailbox., not from a shared mailbox.

Correct?

[PaulCONeil]

Yes that is correct.    Was hoping that I could give a group mailbox a few aliases and that the flow would trigger on receipt of an email to any of them.    Then I could determine which alias the email was sent to and have different logic/targets based on the alias it was sent to.   I can't find any actions that would allow me to determine the alias of the email so I thought I would try the export suggestion provided here.

I think the only way to do what you want is using GRAPH API.

I am trying to build an automated proccess for my accounting.

As I have different cost centers I want to use different Email adresses for each of my cost centers.

now: 

I have an Main active user e.g. 1@Test.com

I now create an alias e.g. a@test.com

Now i build a power automate process:

when an email arrives to a@test.com forward this email to somewhere else.

Power Automate does not activate this process as the alias will not be recognized.

Instead he recognizes "1@Test.com"

How can I solve that?

Thank you guys

Cheers Michael

Have a look at this: https://ivasoft.com/sortaliasessharedflow.shtml

[mr100]

would you be able to tell me where I can find the function "export content activity" in Power Automate?
Thank you.

Cheers

Thank you - but this is way to big...

I am just looking for the solution he found:
Extracting the alias. Would you be able to help me what he meant with "export mail content activity"

Thanks

[VictorIvanidze]

Sorry I know nothing about "export mail content activity".
