• 1. Initial basic checks (please always start here)
• 2. The signature is still not displayed
  • 2.1 Check whether the add-in is active
  • 2.2 Check whether the rules apply

If your email signature is not displayed, in many cases this is not due to a technical error but rather to simple settings or a temporary synchronization issue.

Please go through the following steps in order.

1. Initial basic checks (please always start here)

Before diving deeper, please check the following:

• Are you using the latest version on all devices (Outlook Web, Desktop, Mobile)?

• Sign out of Outlook and sign back in

• Restart your computer or smartphone

• If you are using an add-in:

  • Uninstall the add-in

  • Reinstall it afterward

Note:
If the add-in was deployed centrally by your IT department, Microsoft may roll it out with a delay. In this case, a bit of patience often helps.

2. The signature is still not displayed

Have you completed all steps in section 1 and the signature is still not showing? In most cases, there are two possible causes:

• The add-in is not being loaded

• No applicable rules are assigned to your user

2.1 Check whether the add-in is active

Create a new email (automatic signature)

• Open a new email

• Is the signature inserted automatically?

  • Yes → The add-in is active

  • No → Please continue checking

Open the add-in sidebar (Desktop & Web only)

Note: This step is not available on mobile devices.

• Open the signature add-in sidebar in the email editor

• Important:

  • Is the add-in icon visible?

  • Can the sidebar be opened?

Simply being able to open the sidebar confirms that the add-in is loaded correctly.

2.2 Check whether the rules apply

Sidebar opens, but no signature is shown

• This usually means that no rules apply to your account

• Please review your rules or adjust them for testing purposes

Add a recipient (also important on mobile)

• Enter a recipient in the “To” field

• The signature will then be re-evaluated

• Is it displayed now?

  • If yes, the issue was related to the rule configuration—not the signature itself

3. When should you contact support?

Please contact support if all of the following apply:

• None of the steps above resolved the issue

• The add-in is clearly loaded (icon and sidebar are visible)

• No signature appears despite correct rules
