    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.
