Native external sender callouts on email in Outlook

Hallo,

After our troubles during the weekend, let me share with you the answer I received from O365 support, in reply to my query

1. Can you please confirm if this (External Tag in Outlook) feature is supported also on Outlook for Windows?
1. If yes what are the minimum requirement for office365/Outlook for Windows version/builds?
2. If, no is there a planned release date for this feature to cover also Outlook for Windows?

I hope I can spare some troubles to someone else.

Based on our conversation over the phone on your support request 2949xxxx, the effectiveness of the setexternalinoutlook depends on the version of so many things of which API is one of the most crucial factors on outlook app.

According to this documentation https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.microsoft.com%2Fen-us%2Fpowershell%2Fmodule%2Fexchange%2Fset-externalinoutlook%3Fview%3Dexchange-ps&data=04%7C01%7Cn.guarino%40ebaclearing.eu%7Cda5975dc5be04f4917b908d9e5ce3d4d%7Ca716661474044f3494666fb44a5d2368%7C0%7C0%7C637793496227307804%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=yeCMwsYjqmf3jkBfer3KN2h3Uxu4c8eWarUAeAmhIy4%3D&reserved=0 windows PC was not added to the device listing in the first paragraph. This shows the feature is still not in full release mode.  Hence, I believe there will be improvement in that aspect soon.

Furthermore, in this document https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.microsoft.com%2Fen-us%2Foffice%2Fdev%2Fadd-ins%2Freference%2Frequirement-sets%2Foutlook-api-requirement-sets&data=04%7C01%7Cn.guarino%40ebaclearing.eu%7Cda5975dc5be04f4917b908d9e5ce3d4d%7Ca716661474044f3494666fb44a5d2368%7C0%7C0%7C637793496227307804%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=mv0bnz2j6qbGSWdMmLIw%2B9oXBkyA85EFJnGnWQegpvE%3D&reserved=0 it shows the feature is still in developer mode and it shows the diverse versioning from API to server that will be needed plus exact supported add-ins in windows platform that can facilitate this feature.

Here is the resolution, this feature is available but due to the absence of some of the required prerequisites in your windows PC, the installation or configuration might be unsuccessful for now, as more updates are rolled out the issue will be eliminated.

 
Thank you for choosing Microsoft.

I am afraid we will stay with our good old transport rule for a while.
