I have tried codetwo and I see it put the photos into the active directory thumbnail but it doesn't seem to sync with exchange. OWA, cached exchange mode, or non-cached exchange mode see the imported pictures.
A good email signature generator should play nice with your email platform of choice, whether that's Outlook, Gmail, or anything in between. We favored tools that sync up easily, so your signature is consistently attached to every email without a manual copy-paste every time.
