Provide required information needed to triage your issue

Your Environment

Platform [PC desktop, Mac, iOS, Office on the web]: Windows, Office on the web
Host [Excel, Word, PowerPoint, etc.]: Outlook
Office version number: Microsoft® Outlook® 2019 MSO (Version 2110 Build 16.0.14527.20234) 32-bit
Operating System: Windows 10 Pro version is 21H2, OS build 19044.1469
Browser (if using Office on the web): Chrome

Expected behavior

Message saved as a draft with some custom internet headers in one Outlook client (for example Outlook on the web). I should be able to open the same draft in another Outlook client (for example Windows Outlook) and see the same custom headers.

Current behavior

Message saved as a draft with some custom internet headers in the Outlook on the web. Then I open the draft message in the Windows desktop Outlook the headers are lost. The same happens if I save a draft in the Windows desktop Outlook and try to open it in the Outlook on the web.
If I use the same Outlook client to create and then open a draft message I can access my custom headers.

Steps to reproduce

Compose a message in the Outlook desktop, use add-in to set up some internet headers.
Save message as a draft
Open the draft message in the outlook on the web, use add-in to read the custom internet headers.
internetHeaders.getAsync does not return any values.

Provide additional details

Looks like the different Outlook clients use the different properties to set/get custom Internet headers.

In Win32, all internet headers are saved to a MAPI prop while composing / in draft mode. They are converted to actual internet headers when sending the email.

OWA doesn't care about the Win32 MAPI prop since they handle internet headers differently.

If you do believe The consistency of internet header is important, you can always submit a feature request on our Tech Community Page with the appropriate label(s).
