Hello, When user chatting in Teams 1:1 automated email comes in local inbox. That email contains no headers and it can't be found in 0365 extended mail search. User mailbox is Cloud only, account created on prem then synced to cloud. It started from day one when user account was created. It is happening on local Outlook client and OWA. STEPS TAKEN: Checked Ad-Sync no error, Checked user mailbox flow no error, Checked Teams conversation policy > same as everyone else, User does not have any other devices connected to Teams or Exchange, no federation for this domain, end-user UPN points to Cloud mailbox, Soft delete mailbox is not a option due to VIP position. Please help on the next step and where to look, or what would be the reason. It is only one user. Thank you, _tim

Hi! Do you mean you cannot found the email notification such as missed conversation history or channel messages in outlook? If so, you can try to search these email notifications by sender. You can type “Microsoft Teams” keywords to see if it can be found in your inbox like the following picture: If I misunderstood your requirements, please let us know more details.

Thank you for replying Jimmy :)
End-user is keep getting emails on each reply.
For example I have send you a Teams msg "Hi Jimmy", you reply "Hi Tim" few sec later email comes with Jimmy replied "Hi Tim"

And that is for every single Teams msg, nightmare. So end user is keep deleting these. I really lost all recourse on where and why that is happening for each msg. Only on the local Outlook client. :(

STEPS TAKEN:

cleared Teams app cache

re-installed the app

Configure the chat messages to be “Banner and Email” then close or restart the Teams desktop or close the browser. Then set the notification again back to “Banner only” or off then restart Teams desktop or close browser

Forced log out user to all her devices (via admin center)

New Outlook profile

Removed Win10 creds.

Hi!

Thanks for your replying!

What is your Teams version? My current version is 1.3.00.21956 (64-bit) and we found the message notification cannot find the email in the Teams settings. Maybe you can try to this version to see if it works for you.

If you want to block these Teams message notifications, as a workaround, you can try to block the specific sender in your outlook client. For more details, you can refer to:

Hello Jimmy,
Thx for the link but looks like you did not understand my question ;)
**cleared Teams app cache

re-installed the whole office 365 including Teams app, and yes it is a latest version :) using

https://support.microsoft.com/en-us/help/4027149/how-to-uninstall-office-automaticall

For example I have send you a Teams msg "Hi Jimmy", you reply "Hi Tim" few sec later email arrives in your local client Outlook with the message Jimmy replied "Hi Tim"

There are no headers for that email and it is only saying sender and the body, no subject, see attached.

In the extended mail trace, you can't see that Jimmy sent email to Tim... for example
And that is for every single Teams message
. So the end-user is kept deleting these.
... any thought of troubleshooting :)

Hi!

Sorry for misunderstanding your issue.

Can you see the internal headers like the following picture?

I have consulted with outlook engineer and if you have headers in this box, you can try to copy it and paste it in this site (Link:https://mha.azurewebsites.net/) to analyze the detailed information from it.

Besides, considering this issue is related to only one account, we recommend you try to disable it and recreate a new account to see if it works.

Hi anonymous user

Here are some possible reasons why you receive an unexpected message for your reference:
-The message was released from quarantine.
-The message was awaiting moderator approval and was released.
-The message was spam that was not detected.
-The message matched a rule that added you to the message.
-The message was sent to a distribution list of which you are a member.

Considering this issue is occurred only one user, we recommend you check if you have assigned the specific policy to users.

In addition, please check the mail flow from Exchange Online and found the cause about it. We recommend you go to Mail flow > message trace in the EAC, it will show you what events have occurred to the message before reaching its final status. For more details, you can refer to:
