    Well, the title says it all.
    When I press the send/receive button for my emails accounts, the progress box appears, shows the tasks that are running and ends up with an error stating that the synchronization cannot be completed (the error detail usually states that the server cannot be found).
    However, when I check my emails in Apple Mail on the Mac, everything has been updated - so there seems to be some problem with the internet connection via the VM.
    How can this be fixed?
    Thanks
    Rex

    Hello GampaA. I am now getting the error that the server connection has been interrupted (see screenshot). It used to be the error that the 'server could not be found'. I checked the knowledge base article - it refers to Outlook 2013. Is it still relevant for me as I'm using Outlook 2016 with Office 365? If yes, i will execute the instructions.
    Thanks

    What do I need to check about my internet connection - that it's on, speed, something else?
    Isn't it risky to turn off my anti-virus and firewall? I thought that the purpose of these was to provide a secure internet environment - web browsing, email etc?
    I have increased the timeouts for the Outlook server => no change in performance.
    What is the purpose of running Outlook in safe mode?
    I have not tried repairing the Outlook PST files yet.
