We have a requirement to delete and then programmatically restore calendar events. While our EWS implementation works perfectly, we are struggling to locate the deleted events using the Graph API.\n\n**Current EWS Implementation (Working)**\nIn EWS, we use DeleteMode.HardDelete and then search the RecoverableItemsPurges folder to move the item back to the Calendar.\n\n```\n// How we delete meeting from calendar\nif (msg instanceof MeetingMessage) {\n    MeetingMessage meetingMessage = MeetingMessage.bind(service, msg.getId());\n    ItemId masterId = meetingMessage.getAssociatedAppointmentId();\n    if (masterId != null) {\n        Appointment appointment = Appointment.bind(service, masterId);\n        appointment.delete(DeleteMode.HardDelete);\n    }\n}\n\n// How we restore the message\nItemView itemView = new ItemView(EwsServer.FOLDER_VIEW_PAGE_SIZE);\nitemView.setTraversal(ItemTraversal.Shallow);\n\nSearchFilter filterColl = new SearchFilter.SearchFilterCollection(\n    LogicalOperator.And, \n    new SearchFilter.IsEqualTo(ItemSchema.Subject, message.getSubject()),\n    new SearchFilter.IsEqualTo(EmailMessageSchema.Sender, message.getSender().getAddress())\n);\n\nFindItemsResults\u003cItem> deletedItems = server.getExchangeService()\n    .findItems(WellKnownFolderName.RecoverableItemsPurges, filterColl, itemView);\n\nif (deletedItems.getItems().size() > 0) {\n    for (Item item : deletedItems.getItems()) {\n        item.move(WellKnownFolderName.Calendar);\n        break;\n    }\n}\n```\n\n\n**Problem: Graph API Implementation (Not Working)**\nWhen using the Graph SDK, we cannot find the event in the recoverable items folders after a deletion.\n\nDeletion code:\n```\ngraphClient.users().byUserId(mailboxBeingScanned)\n    .calendar().events().byEventId(eventId)\n    .permanentDelete().post();\n//we have tried delete method as this as well\ngraphClient.users().byUserId(mailboxBeingScanned)\n    .calendar().events().byEventId(eventId)\n    .delete();\n```\n\n\nAttempted recovery code:\nWe have tried searching recoverableitemspurges, deleteditems, and recoverableitemsdeletions using the internetMessageId, but the collection always returns empty.\n\n\n```\nMessageCollectionResponse eventMessage = graphClient.users().byUserId(mailboxBeingScanned)\n    .mailFolders().byMailFolderId(\"recoverableitemspurges\")\n    .messages()\n    .get(requestConfiguration -> {\n        requestConfiguration.queryParameters.filter = \"internetMessageId eq '\u003cMN2PR13...prod.outlook.com>'\";\n    });\n```\n\n**Questions**\n1) When using permanentDelete() on a Calendar Event in Graph, does it land in a different folder than it would via EWS?\n\n2) What is the correct mailFolderId or endpoint to query for items in the \"Recoverable Items\" partition specifically for Calendar events?","author":{"url":"https://github.com/raghucha","@type":"Person","name":"raghucha"},"datePublished":"2026-03-24T01:50:27Z","url":"https://github.com/microsoftgraph/msgraph-sdk-java/issues/2561"}
