Need help with Office 365 signature

[Chrisko22]

I have been using Office 365 for awhile now, and really enjoy the setup simplicity. But I'm having trouble adding a new signature. The signature is created for my Expect Mortgage Co. business and when I launch a new email the signature doesn't auto-fill. It works fine for my other business Expect Technical Staffing.

Does anyone else experience this issue when adding additional signatures?

Thanks,
CHRIS
