Office.context.mailbox.item.itemId is differ in IOS
Hello, I have developed an outlook add-in to save an email to SharePoint list. Which were working fine in web, client, IOS, and android properly. To save an email to SharePoint i read the email using EWS. From few days I notice the add-in is not working properly for IOS. I debug code and found when I request in my service to read email Office.context.mailbox.item.itemId is returning wrong formated id which is not matching with web or client id. To read the email I invoked EWS service EmailMessage.Bind which throws "This protocol does not support ImmutableIds". Some body help me how can i get the proper id in IOS from office context i have tried Office.context.mailbox.convertToEwsId which does not help.
