  1. Hi Richard,

    The Outlook app for Android and iPhone doesn’t support HTML email signatures, unfortunately. This means you cannot insert an image into your signature block.

      1. Because unfortunately they leave out what is needed in apps.
        I now use Aquamail. At least i can set up a signature that is the same as my PC signature

        1. Based on your comment I downloaded Aquamail, but when i pass signature it does not show full proper formatting. It doesn’t show pictures and whole block is with dark semi-transparent overlay. What am I missing here? Can you help please?

  2. My signature does not show when replying to or forwarding an email. It only shows when creating a new email. Can someone please assist me with resolving this issue?

    1. Hi Joel,

      When you put in your signature, it should also work for replies and forwards. When replying or forwarding an email, you may need to expand the window in order to see your email signature there. If you don’t expand the window, it doesn’t show you the signature.

      Hope that makes sense.

  3. Any plans of releasing HTML capabilities? If I leave the signature blank, will it default to the HTML version that is created/saved on my desktop?

    This limitation is surprising and disappointing. A non-HTML signature does not comply with my company’s brand guidelines. It’s also an automatic indicator to my recipients that the email was sent from my phone. As a remote worker, sometimes, I don’t want my recipients to know which device I’m currently using. Honestly, remote or not, I don’t want people to have that info, and a non-HTML signature does just that.

    Perhaps, you’re thinking, “Well, only send emails from your laptop, but that’s not how business gets done.”

    1. Hi Patrick,

      At present, there is no indication that Microsoft will add HTML signatures to their Outlook app for Android and iOS. If you leave the signature blank, your email simply won’t have any email signature. It won’t use your desktop version.

      I completely understand its a frustrating limitation, but we have to work with what we’re given. We also would have thought that a product as big as Outlook would have HTML compatibility for their app, but apparently not.

      As for a workaround, some others have suggested using a different mail client which supports HTML signatures, but I am not sure what your company policy is on that.

    2. I have exactly same issue. I am a medical professional who must often work remotely. Office 365 with HTML signatures are required for company email. Lack of HTML in mobile app is a huge problem for me.

  4. The Outlook app should synchronize with the signatures setup on Microsoft, if you’re paying attention, please fix this.

  5. I’m thinking this was a design based on data prices for mobile devices. When Outlook mobile was originally designed, it may have been an issue sending images back and forth with each e-mail over a wireless carrier.

    Is that still the case? I have an unlimited data plan, so an HTML signatures with an image would not be an issue. Could re re-evaluate this. Right now GMAIL app on android doesn’t seem to support this either – get the jump on Google…

    1. You could be right David. However, with data prices being really cheap these days, you would think an update to the Outlook and Gmail app’s would be in order to allow HTML signatures to work to work on them. We can only hope in the future that Outlook and Gmail app’s will work with HTML signatures.

  6. You can use Blue Mail, with Blue Mail you can use jpg in signature, sync calendar, contacts and several function, Blue Mail is a great app


  7. The mobile outlook app used to support HTML signatures.
    I wonder why it stopped working…
    Someone must have ruined it for everyone else.

  8. Fixed it. You need to declare the document type. I’m on the latest version [4.9.0] as of right now.

    1. Hi Hiraka,

      Interested to know how you got the HTML signature working on Outlook for Android? The document type is already in the raw HTML code which is copied from Gimmio, but it doesn’t work and the signature format ends up looking inconsistent.

  9. Hi Hiraka and Gordon

    May you share how, if you have found a way to add images to the signature in the app for Android/IOS?

    1. Hi Ralitsa,

      Unfortunately at this stage, there is no way to add an HTML signature to Outlook for Android. In order to add pictures to your signature, you would need to be able to add an HTML signature.

  10. It converts the basics like HR and BR. But it drops things like A, images, etc. Yet, they have a link ! ;(

  11. The only solution I found to have an image of my corporate signature is to inserting It by Clicking on attachment “choose photo from library”
