Outlook signature on android mobile web browser

Copper Contributor
I am trying to insert a signature in the mobile web browser version of Outlook 365 at following link:

The "Use my signature from Outlook on the web" option is greyed out and not inserting my signature.

Any advice? Thx

But you can use the "Use a different signature" option? I think you have to configure a signature in the web browser (desktop) version of Outlook web and you will see it in the mobile version?

@Harm_Veenstra Thanks for reply.

Used the only other option but that was text only.

Configured the outlook web app signature but still does not appear on mobile.

Contacted support that said image signature unsupported :facepalm:

Ok, didn't know that.. Perhaps a third party tool like codetwo for signatures is an option? (If it's for your company)

Thanks for the mention. That's right, our third-party tool can be used to automatically convert all emails to HTML and apply email signatures with images, styling and so on. Neither Outlook for Android nor the default Android's Mail App supports HTML email signatures natively at the moment, you can only set a plain-text signature in those email clients (


Making an email signature in Outlook on mobile devices

If you want to add an Outlook email signature using mobile app on iOS, firstly open it and press on the icon of your account.


Then click on the gear icon to enter settings. You will find a ‘Signature’ section there.


Now you can add any text you want to your signature. However, as you might have noticed, there are no editing options.


Note that Android application does not support HTML email signatures.
