    How do I open MS Outlook and Team in my MS Office 2021 Professioinal Plus.  I do not want to use my Email address nor do I want to use a Microsoft account.  I previously used MS 2010 and liked the calendar where I could make meeting times etc without using my email. Is this feature not available without having to create an email in  MS 2021?

    I recently purchased Office 21 professional plus and have downloaded the software.  However, I can't see the individual icons for each of the Microsoft Office applications in the start-up menu.  How can I make them visible so I can start using them? I have uninstalled and installed the software twice.  Thanks, Antonio

    I have repeatedly tried to update to Office 2021 but everytime I open Word it shows the old version and won't let me choose the new version.  I tried inputing product key for Office 2021, but it ignores me and reloads Office 2016.  I hope you have an answer, else I want a refund!  Frown

    after nearly 5 hours of following useless and complicated information on how to install an upgraded version of Office, I realised I had to (1) sign out of microsoft account inside Word (2) make sure ALL versions of Office were uninstalled and deleted even in file history and back up disk (3) PUT MY internet connection into FLIGHT MODE so Office install could not communicate with my Microsoft account (else an install of Office will install the most "recent" version as listed in you M/soft account Order History (4) then, with a clean slate and fully offline, I installed Office 2021.  Opened Word and there it was in Account page of File tab.  So, these instructions are very confusing AND failed to tell you to disconnect from the internet (ie, go into Flight mode) before the update is installed.  I also blame Microsoft, it is their stupid idea to force Office install to run last known version of office as per their account; nothing except disconnecting internet will stop this.  Typical Microsoft Frown

    Followed your instructions to install MSOffice 2021 and it worked, no problems.
    Tip: Use the MSOffice un-installation tool to remove any previous installs.
