    What level of support do you have for the Outlook app for Android and iOS?
    On Android, I'm noticing that 2 column blocks get stacked, but they are left aligned. Social media icons get stacked/left aligned and buttons seem to get left aligned as well. This screenshot ( ) is an example from my Samsung S6 using the Outlook app.
    For my test, I did the following:
    -added a two column row with some text in each column
    -did a "send test" to my email account

    Hi Gharmel, we previously tested the Outlook application in Windows device, as the combination with other SOs represent a low percentual of the worldwide email recipients.
    Thanks for the feedback, recent updates of the application in Windows cause issues with buttons, so time for new tests arrived 😉

    In doing our litmus testing the Android tests are showing stacked columns as being left-aligned. This happens for all the versions I have checked in litmus - 4.4, 5.1, and 6.0 - and is happening for both 2 and 3 column layouts. These are showing in whatever client litmus supports for Android, which I believe is the Gmail app.

    Do you support responsive 2 and 3 column layouts on Android mail clients?

    I'm having the same issue with stacked columns being aligned left on the native email client for Android. I've got it plugged into Office 365 right now The text doesn't seem to be responsively sizing, either.

    Some useful information for Outlook App users:
    - The last versions of the app dropped support for media queries (you can easily find some blog posts and forum threads about this)
    - The weird thing is that media queries perfectly work when using a non-Microsoft email account
    - Litmus announced last August a partnership with Microsoft to improve their email clients. That's their last update:
    Hint: they ask everybody to submit those bugs to Microsoft.

    Having said that, we continue working to handle specific clients issues including the lack of support for modern HTML/CSS.
    Please, use the "follow" link at the top to receive updates about compatibility changes.

    I found a work around for the aligning left issue,
    By replacing the width: calc((int)% – (int)px ); with
    width: 100%;
    in the html output file.

    I just spent hours laying out a beautiful email in BEE, excited about the features and interface, only to realize I wasted my time:

    "Microsoft Outlook for Windows 2007, 2010, 2011, 2013, 2016 *
    * Background images and web fonts are not supported"

    This is a deal breaker for us. We were using Campaign Monitor because their code was solid and consistent across all mail clients — desktop, mobile and web. I wanted to switch to BEE because I like your email building interface. But since so many of our recipients company-wide use Outlook app on Windows, this is unacceptable. There really should be failsafe code for all email clients, whether you consider this to be bloated or not.

    Hi Adfed Team, unfortunately, Outlook usually changes its rendering engine causing issues - it's a known behavior and we are always trying to do our best to make our code as responsive as we can.

    Hello,you do not have a very helpful support center. Where I would normally be able to call or online chat, all that is supplied is a "community forum" where I can wait for my question to be approved. Not a very expedient way to move forward with an online system. 
    That being said I love the BeeFree editor. I need to know how to fix the flyers I create to work in an outlook format. I'm sure you are aware Microsoft cannot read the code well and messes the whole symmetry, font, photos, buttons, and sometimes color scheme up. What are your solutions for this. I am looking forward to keeping my premium membership, but I need it to work on outlook too before I commit to membership for my team and I. Thank you,Michelle 
    PS: Can I input a pre-made flyer and edit it in BeeFree?

    Hi Michelle, thanks for reaching out. I'm really sorry for any confusion. We do offer support to BEE Pro users. You can open a ticket with us by using our contact form ( or the support widget when you are working inside BEE Pro.

    In terms of your questions, you can find more information on how we approach Outlook in this article:

    Finally, you're not able to import pre-made templates into BEE. This is because converting HTML into a BEE-compatible template is unfortunately not technically feasible since HTML documents follow all sorts of different coding patterns, and it's virtually impossible for us to perform an accurate conversion. Sorry that we don't have better news!
