Dear Sir,

Lately, my staff had been receiving the following emails from our clients of the specific domain, with its email content contains question marks symbol in place of tabs and enters (line spacings).

We are using Outlook of the Microsoft Office Home and Business 2013 with the latest version being 15.0.5407.1000.

Our Microsoft Exchange Server is 2019 with all the update being installed.

Our client reported that we are the only company that reported these issues receiving them from their side . I think it is more of the encoding issues.

Is it possible for you to look into this and if possible what configuration needed to be set for the incoming side?

Issues here:

    Hi @Wu Rui Qiang ,

    Welcome to our forum!

    Does this issue occur with all users around you or only some specific users?
    And what's the format of the email?

    According to your description, I noticed that "I think it is more of the encoding issues", which is consistent with what I think. Considering the impact of coding, please double click to open the email>in Move group click Actions>Other Actions>Encoding to check what the coding is.

    If it's not Unicode (UTF-8), please change to it and check if there're any differences.

    In addition, considering that the screenshot you provided contains personal information, I have hidden it in order to avoid privacy disclosure. Please remember to hide your personal information before uploading.

    Of now it is for the two staff, we are actually referring to our RECEIVING side (receiving emails from the our clients of that specific domain), not our sending side.

    The one you recommended us to configure is based on the sent Folder email function right? I wonder whether it will work or not. Is there a similar setting for the receiving side?

    Hi, my apologies for the long delay in response here, we are still receiving the emails with Question Marks from our clients of that specific domain. Any solutions to be set up for our receiving side on both client and webmail?

    As above, please help, after some monitoring, the CISCO engineer had pointed out our Microsoft Exchange 2019 server configuration may be the cause, not on their CISCO ESA, the additional character is likely added by the server itself. She referred me to check with you to resolve the issue.
