Hi @whoanuragverma
This issue I see on a customer online session, I only have time to see it occurs on OWA.
And only with simple code snippet is:

Office.context.mailbox.item.saveAsync((res) => {
if (res.status.toString().toLowerCase() === "succeeded") {
ewsId = res.value;
// convert the item ID to a REST ID
id = Office.context.mailbox.convertToRestId(res.value, Office.MailboxEnums.RestVersion.v2_0);
resolve(id);
console.log(id);
} else {
resolve();
reject();
}
});

After that I use for call additional API to our back-end that use some EWS connection, but it return ID malformed error

I use some console code to check and I see request on customer machine request have this header.. so wonder why it happens on Outlook and where to turn on or off this on Outlook since I never heard Outlook have kind of this setting

What error are you getting while making the EWS request?

[ttuyen1529]

here... @whoanuragverma
that why I take some investigate and found out that ID is ImmutableId

[whoanuragverma]

I see you are trying to make an EWS call but you are converting it to Outlook REST API Id in the snippet you provided, can you try sending the EWS request without converting to Outlook REST ID?

It is mentioned in our docs as well, these two IDs are not identical. https://learn.microsoft.com/en-us/javascript/api/outlook/office.messagecompose?view=outlook-js-1.11&preserve-view=true#outlook-office-messagecompose-saveasync-member(2)

@whoanuragverma I already tried that and it is the same..
Only one way works is actual using ID return from getItemId function and call EWS..
And noted that this is actual running product, and only see this in one of our customer tenant, so...
