Hi @Trisha Bjorklund ,
Welcome to our forum!
Looks like your issue is more related to Outlook for Android. Based on my research, i found a thread mentioned that you could export signature from Outlook for desktop and then import it to Outlook for Android. It's suggested that you could refer to it: Matching Mobile to Desktop Signature.
If it doesn't help, please kindly understand that the Outlook tag here we mainly focus on general issues about Outlook desktop client. In order to better solve your problem, it's suggested to post your issue on this dedicated forum for Outlook for Android for more professional help.
Thanks for your understanding and support!
