Using older versions of Outlook for Mac in business environments
Hi Leo,
Assuming the scenario is identical;
Outlook>Preferences>Signatures
select the signature in use so it shows up in the right hand pane for editing
Where there is a URL e.g. email address, right click>Hyperlink>Edit Hyperlink
In the Edit Hyperlink pane you then see a typo error as the "text to display" field may be different to the "email address" field for example.
For me this must of existed prior to the MS office upgrade, but the upgrade exposed it.
