SUMMARY


This article describes troubleshooting why email signatures do not appear in OWA when composing email.


INFORMATION


The following are common reasons why email signatures that have deployed without any errors do not show in OWA when composing email:


  • HTML signature size exceeds maximum size imposed by Exchange Server and is not configurable. In Exchange Server 2007, the maximum signature size is 16KB, and in Exchange Server 2010, 2013 and 2016, it is 8KB. Remove white space from HTML template to decrease size.

  • OWA Light supports only plain text email and signatures. If a Plain Text template has not been created, then no signature will be applied when composing email in OWA Light. When using a web browser that does not support the full feature set, OWA opens in the light version.
