Hi @Mirtemir ,
Do you want to Save contact to Outlook from PowerApps?
I have made a test for your reference.
1.Create a flow.
json(outputs('Compose'))
Schema:
{
"type": "object",
"properties": {
"AccountEnabled": {
"type": "boolean"
},
"BusinessPhones": {
"type": "array"
},
"City": {},
"CompanyName": {},
"Country": {},
"Department": {},
"DisplayName": {
"type": "string"
},
"GivenName": {
"type": "string"
},
"Id": {
"type": "string"
},
"JobTitle": {
"type": "string"
},
"Mail": {
"type": "string"
},
"MailNickname": {
"type": "string"
},
"OfficeLocation": {},
"PostalCode": {},
"Surname": {
"type": "string"
},
"TelephoneNumber": {},
"UserPrincipalName": {
"type": "string"
},
"mobilePhone": {}
}
}


2.Create a app.
SaveContactinOutlook.Run(JSON(Office365Users.MyProfile()))
