We’ve encountered a discrepancy with mailboxItem.getInitializationContextAsync. In Outlook on the web(OWA), asyncResult.value returns a string, whereas in the desktop version, it returns a JSON object.

https://learn.microsoft.com/en-us/office/dev/add-ins/reference/objectmodel/preview-requirement-set/office.context.mailbox.item#methods

Because of this inconsistency, JSON.parse of async result fails on the desktop version, while it works fine in the browser.

Maybe it is possible to determine the type of the value (probably using typeof and instanceof). If it is a string, the use JSON.parse. Otherwise, use the object that is already made.

However, the wrong documentation should be fixed.
