Using older versions of Outlook for Mac in business environments
Last week I had numerous chats with MS second level support and a clean install of Outlook on an installation package they sent me the outcome of which was that legacy for Outlook for Mac is broken. They acknowledge that and their work around is the use of New Outlook which I find unusable for my purposes. They informed me that they will escalate and try and accelerate a fix and would contact me once a week to provide progress - which of course they have not done! Go figure! It's Microsoft!
I am currently using Spark which I am quite enjoying. Its different and requires some getting used to. But it's very responsive and so is the support who I have been in touch with to learn how to use and set up. They are a Ukrainian outfit and their enthusiasm and drive to succeed shines through.
