In Dynamics 365 on-prem, I have created a Email signature with some text bold text and hyperlinks in it (email address/website URL etc).

When I try to forward an existing email within CRM and use the above created signature (i.e. "insert signature") and click on Save button it (before sending) then that save operation makes the signature text disappears all of sudden.

This seems to be random behaviour and possibly depends upon the FROM field value of an user vs Queue name!! May I get some help as to how to troubleshoot and possibly resolve this issue. Has some experience this issue before? Is this caused because of browser type or its settings etc.

Thanks in advance, AR
