We have the same issue with the To, Cc, Bcc fields. We've also tried Office.context.mailbox.item.to.setAsync([],console.log). The To, Cc, Bcc fields are cleared after calling this method but the Web interface is not updated and shows the one of the recipients in the field.

We also have the same issue. Empty array does not "remove" all recipients in the field(to/cc/bcc) anymore. When provided with at least one recipient in the array, it does work as expected.

Hi @exextoc! Any update regarding this issue?

Hi @ElizabethSamuel-MSFT and @exextoc . Indeed also very much hoping on an update! Thanks!

[exextoc]

Apologies for late reply on this. We somehow missed looking at this issue.

We tried reproducing this issue by setting 3 recipients in "Bcc" field and then running following code from add-in. This code was able to remove all recipients from 'Bcc' field successfully.

Office.context.mailbox.item.bcc.setAsync([], function(asyncResult) {
  if (asyncResult.status === Office.AsyncResultStatus.Succeeded) {
    console.log("Succeeded in setting Bcc field.");
  } else {
    console.error(asyncResult.error);
  }
});

Question: Can you please share video from "Outlook Web" running this add-in code and then showing "Bcc" field is not getting updated?

@exextoc, sorry, but I cannot reproduce this issue anymore. It seems to have been fixed. Thank you.
