Hi, I’m struggling with the Microsoft 365 Mail module. I want to send one mail to multiple recipients. For that an array is required, so this is my setup: ![image 2025-02-12 um 21.40.26](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/8/c/8c3492c8eeb04556cfa0d8174b0f1b9ff8d09962.png) ![image 2025-02-12 um 21.44.19](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/7/7/77663e31be7a9fb60144df1c36e9750e06f86067.png) However: I get an error of the mail module saying “Array of objects expected in parameter ‘toRecipients’.” What exactly is required here? Does someone have an example? Seems like a more complex arrays is required? Thanks a lot! ---

@Leo Hi, I think the following post is helpful. > [@Sending email to multiple CC's](https://community.make.com/t/sending-email-to-multiple-ccs/35561/3): > > According to the [sendMail endpoint](https://learn.microsoft.com/en-us/graph/api/user-sendmail?view=graph-rest-1.0&tabs=http) on the Microsoft 365 Mail Documentation, toRecipients field accepts an array of collections, each looks like this: { "emailAddress": { "address": "frannis@contoso.com" } } So you’ll need to build the array using an aggregator, so your final structure of the array variable will look like this: "toRecipients": [ { "emailAddress": { "address": "frannis1@contoso.com" } }, { "emailAddress": { "address": "frannis2@contoso.com"… According to the above post, it appears that the following structure needs to be created. It also says that you need to enter the `ToRecipients` in Map. ```auto "toRecipients": [ { "emailAddress": { "address": "test1@contoso.com" } }, { "emailAddress": { "address": "test2@contoso.com" } }, { "emailAddress": { "address": "test3@contoso.com" } } ] ``` ---

Oh great, that’s a good insight! thanks! However, now I’m really struggling getting to this format 😕 My approach: Array aggreagtor first ![image 2025-02-13 um 10.09.21](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/d/8/d8df37f521e88591602288969d7edb9ebcd63db3.png) and setting the variable like that: ![image 2025-02-13 um 09.02.38](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/2/f/2fb85422e24575f72bb70e24d0652ca8a70bf796.png) However, the result: ![image 2025-02-13 um 09.03.03](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/7/2/7292435a3d223938ebbebf87c2bf2502cb822bf8.png) Is it the right approach? any chance for some more help? 🙏 ---

My simple but “ugly” solution so far: Switch to the general E-Mail module and login with the MS account. There a simple array of mail is good enough for multiple recipients… thanks MS 😅 ---

@Leo Sorry for the late reply. I also need to apologize for one more thing. There were some errors in the `toRecipients` that I pasted in my first response and I have corrected them. The best I can come up with is to create a scenario like the blueprint below. [blueprint\_createToRecipientsJson.json](https://community.make.com/uploads/short-url/4aqexLounMLJ1YX0tifDpnkhs4U.json) (17.0 KB) It is difficult to explain in text only, so I would like you to take a look at the blueprint. But for a brief explanation, the values of the Array Aggregator are retrieved one by one in Repeater and aggregated in Text Aggregator. Only the last loop of Repeater has a separate branch in Router. I didn’t want to include commas, so I split the branches. The final output of blueprint has the following structure. ```auto { "emailAddress": { "address": "test1@contoso.com" } }, { "emailAddress": { "address": "test2@contoso.com" } }, { "emailAddress": { "address": "test3@contoso.com" } } ``` I think it would work if you could enter the following into the Outlook module. Replace the `${output}` with the value output by the Text Aggregator. ```auto "toRecipients":[ ${output} ] ``` ---
