Skytech webmail? Open your webmail, click Settings, then Identities, click your email address, and type your signature in the Signature box. Click Save. The name may be slightly different on your webmail.
One signature may not appear everywhere. Signatures made in New Outlook or on the web are usually saved with your Microsoft 365 mailbox, so they show wherever you use New Outlook or the web. Newer Classic Outlook versions also save signatures with a Microsoft 365 mailbox, but a signature stored on that one computer (or used with Skytech-hosted IMAP email) stays on it, and the phone app keeps its own. If you use more than one place, check each one.

Your signature is set

Send an email to yourself to check how it looks, on your computer and on your phone.

Still not working?

My signature does not appear on new emails

Open your signature settings and check the New messages drop-down. It must show your signature name, not (none). In Classic Outlook, also check that the right E-mail account is chosen at the top.

It shows on my computer but not on my phone

Your phone app keeps its own signature. Follow the Phone app tab and type it there.

My logo shows as a red X or an attachment

Some email programs block pictures. Keep the logo small and put your name and phone number in text. Do not use the whole signature as one picture.

The signature appears twice

You may have it set for both new messages and replies, or you typed it into the message by hand. Choose (none) for replies, or delete the extra copy.

I cannot find Signatures in my settings

The name or place changes between versions. Look under Mail and Compose and reply. If you still cannot find it, message us a screenshot (see Take a screenshot).

Still stuck? We'll sort it out.

Message the Skytech team and we'll help you directly.
