Outlook 365 Connector: ODATA query: filter Contacts by email address



I am trying to find out whether a Contact with a specified email address already exists, but I am having trouble figuring out the exact syntax. 


My difficulty relies on the fact that the Contact has a collection of email addresses, not a single one, so I am not sure hw to filter a sub-property, and I would not like to fetch the whole Contact set and iterate one by one, it would not be efficient.


I have been tryint to bang the 'in' comparison operator. like this: 


 'someemail@addr.ess' in emailAddresses.Address

 'someemail@addr.ess' in emailAddresses/Address


But I am getting an invalid filter clause error. 

I am assuming that the 'in' operator would be able to look each item from the collection and return true on a match. Maybe I misunderstood the ODATA documentation? 


Any help is appreciated, thanks!

Hi @TiagoFreire ,


Could you please share a screenshot of the configuration of your flow?

Please share more details about your flow and explain more details about your requirement and we could try to provide a proper workaround for you.


Best regards,

Here is the context: 



1) parse all email addresses in the From: and CC: fields

2) check if a Contact already exists for each

3) if there is No Contact, create a contact.


What is working:

A PowerApps button sends in a text string - it's actually a JSON which I then parse into several parameters. 

One of those Parameters is a Message_ID for a specific email in a specific Outlook 365 account. 

I can fetch the message from the specified email account. 


What is not working: 

I want to use Get Contacts (V2) to fetch a collection of Contacts which have a specified email as one of its addresses, using a Filter Query.

The Filter Query will avoid having to do an exhaustive loop over every Contact, which is very time-consuming, and does not scale well.

The Body of the Output Error is: 

  "error": {
    "code": "BadRequest",
    "message": "Invalid filter clause",
    "innerError": {
      "request-id": "some-uuid-very-long",
      "date": "2019-08-02T20:15:29"




according to some recent flow documentation I found it should be 


emailAddresses/address eq ''


but that fails as well with invalid filter clause.


As a workaround I store the email address also on a top level field. But of course that is not how it should be.


If anyone knows how to solve this, please help.



This is an old post of mine. if memory serves me well, I later learned that the Filter query here does NOT use ODATA syntax. it uses the userland search logic, like when you do a plain search on Outlook Web's search box. 


That on one hand is intuitive for certain actions. but for tech heads it is limiting. 

One cannot search for messageId or internetMessageID, two extremely useful properties to track emails.

Put this in "Filter Query":
emailAddresses/any(a:a/address eq 'someemail@addr.ess')
