Sadly Microsoft Outlook for Mac does not allow HTML email signatures but there is a solution — an additional plugin by element26 for $2.99 which adds the ability to install a Mirosign HTML email signature on Microsoft Outlook for Mac 2011, 2016, 2019 and 365.
We do recommend using alternative mail programs for Mac if you require a good looking email signature. Try using Mac mail native email app or Spark mail instead.
Step 1 — Create your signature
Create your email signature in Mirosign.com.
Step 2 — Install HTML Email Signature plugin
Purchase and install HTML Email Signature – Outlook for $3.99
This is an independent third-party plug-in that allows html email signatures to be added to Outlook for Mac. After a recent update we have had slight problems with the email signatures displaying in google app on iPhone after sending from Outlook for Mac with this plugin.
Step 3 — Open Outlook for Mac signature settings
Open Outlook for Mac
Select New Email.
Select Signature > Signatures.
Select + and type a name for the signature called “Mirosign.com”
Step 4 — Copy HTML signature code
