I’m working with both Outlook and Outlook Web App (OWA) and therefor want to configure the same default signature in both clients.

To do this, I opened the Signature Editor in Outlook and copied my signature text. Then I logged on to OWA and pasted the signature in the Signature Editor there. However, when pressing “Save Settings”, I get the error:

The text you typed is too long. Please shorten it and try to save it again.

This made me wonder; Up to how many characters are allowed for the Signature in OWA?
