Can I use immutable identifiers link from GRAPH API in office.js.api? Somehow setting needed header to make identificatory not changeable if email is switched from Draft to Sent folder for example?

CodePudding user response：

No. Immutable IDs do not work with any office.js apis. The only itemID available is the EWSId via Office.context.mailbox.item.itemId. However, as you noted the EWSId will change if the item switches folders.

You may be able to use Graph/REST to translate the EWSId into immutable: https://docs.microsoft.com/en-us/graph/api/user-translateexchangeids?view=graph-rest-1.0&tabs=http

But Office.js inputs/outputs are always EWSId's in the function.
