MessageDeliveryFailedException: Failure code: 9932

Question

Hello everyone,

I have been having three users get an error message only whenever they reply to an email on their mobile phone, the desktop app works fine. I have tried to look up the error but I cannot find anything about the issue. We have an exchange server 2016, I recently updated our CU and I think this could be the issue. The full error message is
technical details MessageDeliveryFailedException: Could not deliver the message [len=70, data=00000000.... sent at 4/22/2024 11:09:20 PM. Failure code: 9932

Any help would be greatly appreciated.

Hi,

Based on your description of the issue, the problem may be with the Outlook mobile client, as you have updated the version of Exchange 2016, which may result in unsupported versions of certain outlook versions, I would like to confirm the following information with you so that we can better troubleshoot your issue:

1. May I please know if this issue is particular to the three recipients or all recipients are affected when using mobile?
2. Can these three users send emails normally or is it only when replying to emails that the error is reported.
3. What mobile client are they using?Native mail App or Outlook for Android/IOS？ Is the outlook mobile they are using a new version or an old version, if it is an old version please try to update it, if it is a new version please try to fall back to the old version.
4. Check if the UPNs of these users match the SMTP address.

Please feel free to contact me for any updates！

I've already opened a ticket with the mobile app support, but the process is moving very slowly. It seems like Microsoft is playing ping pong. Follow my example and also open a ticket through the mobile app; maybe then the process will go faster. My ticket number is 1059288513. You can reference it and also include the link I provided above in your request. Good luck to everyone."
