Outlook on your phone

In Outlook for iPhone and Android, Microsoft's steps are: open Settings, then under Mail, tap Signature. You can set one signature for all accounts or turn on Per Account Signature. Microsoft doesn't say whether a pasted signature keeps its pictures there, so we don't make a claim about it.

Pictures and logos

Classic Outlook for Windows blocks automatic picture downloads by default. A reader who sees an empty box where your photo or logo should be can click “Download Pictures” in the bar at the top of the message, or add you to their Safe Senders list so pictures from you load from then on.

Your photo and logo are ordinary image links on your own host. The HTML we copy doesn't attach them to the message.
