Email signature disappeared after moving to new Outlook

After switching to the new Outlook, saved signatures vanish, stop being added to new messages, or only one signature can be kept.

What you’re seeing

  • After switching to the new Outlook, the signature that was there for years no longer appears on new emails.
  • The signature exists in settings but isn't added automatically to new messages or replies.
  • Logos and images in the signature show as broken boxes or vanish entirely.
  • Different signatures for multiple accounts or for replies seem to have collapsed into one, or into none.

Common causes

Every environment is different, but these are the causes our engineers find most often:

  • Classic Outlook stored signatures on the PC, while the new Outlook stores them with the mailbox, so they do not always carry over.
  • Default signature choices for new messages and replies were not set again after the switch.
  • Images embedded from the local PC or referenced from old locations do not survive the move.
  • A third-party signature tool was built for classic Outlook and does not integrate with the new version the same way.
  • Signatures created on one account do not apply to other accounts or shared mailboxes added in the new Outlook.

Why it matters

Email signatures carry contact details, licensing numbers, legal disclaimers and the brand look clients expect. When they vanish, emails look less professional and customers lose the quick way to call back. In regulated industries, missing disclaimers can create compliance problems. Staff also waste time recreating signatures by hand, each slightly different, which undermines a consistent brand.

Frequently asked questions

Can we get our old signatures back?

Often yes. The old signature files are usually still on the PC from classic Outlook and can be reused if they haven't been deleted.

Is there a way to make signatures consistent for everyone?

Yes. Many businesses manage signatures centrally so every employee's email looks the same regardless of which Outlook they use.

Can AskTechGurus set this up remotely?

A certified US engineer can help in a remote secure session, from $99, and you pay only when it's resolved.
