Hi, Chaz Stewart
Good day!
Thank you for posting to Microsoft Community. We are happy to assist you.
According to your description, I understand that you would like to synchronize your signature across devices automatically
Unfortunately, it is not attainable for Outlook on android mobile devices. Nevertheless, as a work around that you can save the signature file to your OneDrive or other cloud storage service and access it from any device.
To export your signature from the desktop version of Outlook, you can follow these steps:
1. Open Outlook and click on "File" in the top left corner.
2. Click on "Options" and then select "Mail" from the left-hand menu.
3. Scroll down to the "Signatures" section and click on "Signatures".
4. Select the signature you want to export and click on "Copy".
5. Open a text editor (such as Notepad) and paste the signature into the editor.
6. Save the file with a .txt extension.
To import the signature into the mobile version of Outlook for Android, you can follow these steps:
1. Open Outlook for Android and tap on the three horizontal lines in the top left corner.
2. Tap on the gear icon to open the settings menu.
3. Scroll down to the "Signature" section and tap on "Edit signature".
4. Tap on the three dots in the top right corner and select "Import".
5. Select the .txt file you saved earlier and tap on "Import".
Thanks for your precious time and your understanding would be highly appreciated.
Hope you all the best!
Sincerely,
