  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. Go to
        Upload your logo to convert to Base64 format.
        select [Show Code]
        ‘For use in elements:’ [Copy to clipboard]
        Copy the code into an email on your PC and email to your Android phone.
        Copy and paste the code into Outlook’s signature box, and then add the following to the front of it

        The apostrophes are important that they’re the correct one’s.
        When I tried using the apostrophe on my Windows PC, it didn’t like that one, so make sure you type it on the Android phone instead.
        Note: once you’ve setup the sig, Outlook will turn it in to a weird, coloured box if you go look directly at the signature box again.
        If you need to edit your signature, you’ll have to re-paste the code again to get the logo again.
        Probably best to keep the email with the Base64 code in your drafts or another folder.

        1. Hello Adrian, what apostrophes are we talking about? There is no symbol inserted by you or I can’t see any! Thank you!

  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.

      1. The pasted signature works for new and forwarded emails, but NOT for reply/reply all.
        Any ideas?

  3. I Use typeapp Mail software for android and very happy with it. You can insert image as signature

  4. 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.

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

  6. 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.

  7. 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


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

  9. 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.

  10. 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.

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

  12. 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”

  13. This has to be the most unprofessional aspect Android has overlooked. Definitely thinking of moving to iPhone for business.

  14. I’m using Outlook for Android and it seems to work okay. I’ve got a signature setup in the Outlook desktop client, I’ve deleted the ‘Get Outlook for Android’ signature on my phone and it seems to just use my signature from Outlook. Edit – hang on, I also have an Office 365 account, so that could be what’s doing it but it does work for me, once I removed the ‘Get Outlook for Android’ on my phone (It was just sending that before).

  15. I have 2 different accounts through 365. When I follow the signature directions on my mobile device (an Android), it uses the same signature for both accounts. How can I make 2 different signatures, one for each account? Thanks!

  16. My Android device have always supported HTML signature in Outlook App, infact currently, I have that set up.

    I was trying to setup a new account recently and it suddenly stopped working.

    Was there any changes recently to the ‘Outlook’ Application from Microsoft?

  17. Hello,
    I am now full time working from home so have purchased a Chromebook. As great as it is, there are a few minor issues with it. The main one being the fact that i cannot add my company logo to my signature on outlook (app downloaded) I have also tried Gmail- same situation occurs.
    Anyone found a way around this?
    Not the end of the world for me, but comes across more professional with a logo attached.
    Happy to try other mail platforms if anyone can recommend any?


  18. Hello All,
    I have found a workaround for getting your signature onto the mobile app. By sending yourself an email with your signature from the PC, and then opening it on your mobile and forwarding it, and then edit the forwarded message, the signature will remain when you send that email.
    But the hassle now is that every time you need to send an email, you have to use the email with your signature and forward it and edit it before sending it.

  19. Very disappointed with the Outlook App. Have tried to use it many times but just fails to impress. Main reason now is the same as everyone else, not able to add company logo to signature block. I don’t want people to know whether I’m on my computer or phone, want it to be seemles integration with desktop or online. Once again,I will delete it.

  20. Same issue, Sept 2021 company has facebook and linkedin logos after website link in signature and can’t see how to make it work, thanks for this discussion though!

  21. Why has NOBODY bothered to answer this???

    Open the signature editor (click on ‘signatures’ on the drop-down list of signatures in a composer window), click the drop-down selector next to ‘replies’ and select the signature that you would like used for replies. You will note that the signature is already selected for ‘new emails’ just above this- just replicate your choice for replies also.

    Why are signatures not automatically added to replies by default? Well, that would be because announcing your signature and its twenty oversized logos, poorly-formatted hyperlinks and legally-dubious disclaimer at the foot of every single reply in an email chain wastes bandwidth and storage (and therefore energy), looks awful, and hinders attempts to locate any meaningful information- the average conversation by email consists of about a kilobyte of text and a megabyte of visually-unappealing crud.

    Something to keep in mind.
