Unable to retrieve all attachments from forwarded Outlook emails using Graph API
We have integrated Outlook with our system using Microsoft Graph API and subscribed to message events. Whenever we receive an event, we process the email message at our end. Currently, we are facing an issue related to attachments in forwarded email conversations. Scenario An email conversation contains multiple replies. Some of these replies contain attachments. When a user forwards the entire email thread, Outlook generates a forwarded email that includes the conversation history in the email body. Problem When we receive the forwarded email event and fetch the message details using the Microsoft Graph API, we observe the following: The forwarded email only contains the latest reply's attachment. Attachments from earlier replies in the thread are not included in the forwarded message attachments. In some cases: The first reply contains an attachment. Subsequent replies do not contain attachments. When the user forwards the email, the forwarded message JSON shows: hasAttachments: false But, the forwarded email body still contains the previous conversation that had attachments. Our Questions Is there a way to retrieve all attachments from the entire email thread when a conversation is forwarded? Can we retrieve these attachments using the current user's access token via Microsoft Graph API? If there is a way, please also let us know how we can identify forwarded emails using the Microsoft Graph API, so that we can apply this solution only for forwarded emails. Our Requirement We need a reliable solution that works in production to ensure that all attachments from the email conversation are retrieved, even when the email thread is forwarded. This issue is currently impacting our production system, so we would greatly appreciate any guidance on the correct approach. Thank you in advance for your support.
Is principalId Always a GUID in Microsoft Graph ??
{ "error": { "code": "Request_BadRequest", "message": "Invalid GUID:HR", "innerError": { "date": "2026-02-13T06:44:24", "request-id": "87678d90-1d94-4131-a705-4356ad3568a4", "client-request-id": "63569c7b-1dea-42d4-8d72-aa3668c78418" } } } We’re encountering an issue with the Microsoft Graph API response for directoryRole Recently, one of our Graph API calls started returning a response where the principalId value appears to be a custom string instead of the expected GUID. In our code, we loop through each id from the delta response, assuming it will always be a valid GUID. However, we are now getting errors because one of the returned principalId values does not match the expected format. Our questions: Is it possible for Microsoft Graph API to return a custom string instead of a GUID for principalId? Has anyone experienced similar behavior with delta queries for directoryRole or any other object? Are there any known scenarios where the principalId format differs from the standard GUID? Any insights would be appreciated.Resource not found while trying to access the available resource
I am attempting to automate CRUD operations on Microsoft Entra objects using the Microsoft Graph API. However, I am encountering a Resource not found error when accessing a resource programmatically, even though the same resource is accessible without issue when invoking the API endpoint via Postman.
Alias for Refinable Managed Property Not Working in Search Queries
Hi, The alias for the refinable managed property has worked as expected in sortProperties for the past year, but it has recently stopped working and now returns an error. Using the original managed property name (RefinableDateSingle01) continues to work as expected. The error is shown below, together with the trace ID. Unfortunately, we are unable to switch to using RefinableDateSingle01 in sortProperties as it does not meet our business requirements. We are currently facing challenges due to the large number of SharePoint sites, many of which we do not have permission to access. As a result, we can only confirm that the refinable managed property RefinableDateSingle01 and its associated alias are configured correctly on the SharePoint sites where we have full access. What is the root cause of this issue, and how can it be resolved? https://graph.microsoft.com/v1.0/search/query { "requests": [ { "entityTypes": [ "listItem" ], "query": { "queryString": "* AND SiteId:\"siteId\"" }, "from": 0, "size": 50, "sortProperties": [ { "name": "RefinableDateSingle01", // This works when I use the refinable managed property name (RefinableDateSingle01), but it does not work when I use the alias I defined for this property "isDescending": false } ] } ] } 500 Internal Server Error (When I used alias in sortProperties) { "error": { "code": "InternalServerError", "message": "The call failed, please try again.", "target": "", "details": [ { "code": "InternalServerError", "message": "The call failed, please try again.", "target": "", "details": [ { "code": "InternalServerError", "message": "The call failed, please try again.", "target": "", "details": [ { "code": "InternalServerError", "message": "The call failed, please try again.", "target": "", "details": [ { "code": "InternalServerError", "message": "The call failed, please try again.", "target": "", "details": [ { "code": "InternalServerError", "message": "The call failed, please try again.", "target": "", "details": [ { "code": "InternalServerError", "message": "The call failed, please try again.", "target": "", "details": [ { "code": "InternalServerError", "message": "The call failed, please try again.", "target": "", "details": [ { "code": "FanoutDownstreamContradiction", "message": "The call failed, please try again.", "target": "", "details": [ { "code": "TwoStepFanout_FirstStepFailed", "message": "The call failed, please try again.", "target": "", "serviceName": "Xap", "moduleName": "SubstrateSearch.FanoutV2.MultiDimensionSearchFanoutPluginV3", "contactTeam": "3sdri", "httpCode": 500 }, { "code": "FanoutDownstreamContradiction", "message": "The call failed, please try again.", "target": "", "serviceName": "FanoutService", "moduleName": "Fanout", "contactTeam": "3STenantSearchDevs", "httpCode": 500 } ], "serviceName": "FanoutService", "moduleName": "Fanout", "contactTeam": "3STenantSearchDevs", "httpCode": 500 } ], "moduleName": "SubstrateFanoutSearchWorkflow", "httpCode": 500 } ], "moduleName": "AscUserSearchFanoutWorkflowV2", "httpCode": 500 } ], "moduleName": "AscUserSearchFanoutWorkflowV2", "httpCode": 500 } ], "moduleName": "G21AscWorkflow", "httpCode": 500 } ], "moduleName": "TenantFileSearchFederationWorkflow_ASC", "httpCode": 500 } ], "moduleName": "TenantFileSearchFederationWorkflow", "httpCode": 500 } ], "moduleName": "FederationWorkflow", "httpCode": 500 } ], "moduleName": "TopLevelWorkflowBase", "httpCode": 500 }, "Instrumentation": { "TraceId": "57c005b9-07fc-453b-8c73-2650d90670e0" } }
The specified object was not found in the store., The process failed to get the correct properties.
Hi, I've set up a change notification using the Microsoft Graph API so that Microsoft sends webhook notifications to our server whenever a new email arrives in a specific mailbox. Each notification includes the ID of the new email. Our server then uses this ID to retrieve the email body via an HTTP GET request to Microsoft Graph. However, we've encountered a few instances where the server receives a error when attempting to retrieve the email. The error message is: Error Message: Exception: Microsoft.Graph.Models.ODataErrors.ODataError: The specified object was not found in the store., The process failed to get the correct properties. Has anyone experienced this before or have any insights into why this might be happening? Thanks!
Correlation between Microsoft Graph Events and bookingBusiness Appointments
Hi everyone, I'm struggling with getting complete attendee information from calendar events. I can successfully get event details from the /events endpoint, but it lacks full attendee information and other details compared to the bookingBusiness/account-id/appointments endpoint. The problem is, I can't find a way to correlate and event and its various ID's and a booking appointment ID. Is there a recommended way to get full attendee details while working with calendar events? Any help would be appreciated!Graph API permission issue to update Office 365 group settings via Application user(ClientId/Secret)

Dear community A third-party monitoring application creates static adaptive cards when an alert is triggered. This application calls a PowerShell script and provides a couple parameters including the adaptive card json. I have now tried to pack this adaptive card into a html email and send it via Graph API. Sadly I cannot get it to render the adaptive card for example in Outlook. HTML message <html> <head> <metahttp-equiv="Content-Type"content="text /html;charset=utf-8"> <scripttype='application /adaptivecard+json'> {"type":"AdaptiveCard","version":"1.4","hideOriginalBody":true,"body":[{...}]} </script> </head> <body> </body> </html> Graph Mail $emailRecipients = @( 'email address removed for privacy reasons' ) [array]$toRecipients = ConvertTo-IMicrosoftGraphRecipient -SmtpAddresses $emailRecipients $emailSender = 'email address removed for privacy reasons' $emailSubject = "Sample Email AdaptiveCard" $emailBody = @{ ContentType = 'html' Content = Get-Content -Path 'C:\...\adaptivecard.html' } $body += @{subject = $emailSubject} $body += @{toRecipients = $toRecipients} $body += @{body = $emailBody} $bodyParameter += @{'message' = $body} $bodyParameter += @{'saveToSentItems' = $false} Send-MgUserMail -UserId $emailSender -BodyParameter $bodyParameter I am grateful for any advice or help with this problem.
