With Fully server-side setting enabled, the default/reply email signatures are added when the email is sent. The email signatures are visible at the recipient end, not when you compose the email.
The default email signature is added at the bottom of the email chain. The reply/forward email signature is added in the email chain.
If a 'divider' is found in the email chain, the reply signature is added above the divider' (screenshot below). The 'divider' is found in Outlook on Windows/Mac and in Outlook on the web (browser).
For Mobile devices, we recommend using Outlook for iOS and Outlook for Android for the best experience. Xink also works with the native Mail app for Android and iOS.
Office 365 environment is required.
