Cannot edit signature on outlook 365 mail

Copper Contributor

I recently subscribed to outlook 365.  I am not able to edit my signatures for emails. When I go to File - Options-Mail-Signature I am unable to open and or edit Signature.

My old signatures are still there  but I cannot edit or add new signatures.


Can anyone help?

In Outlook, Go to File --> Options-->Mail-Signature . Then you can add new signatures using New action. 


For editing the signature, select the required one from the list, then it will populate the content below. save the content once edited and check. 


Let me know if this works for you.

First thing I tried.

Nor response when I hit Signature nor can I edit.
