Office 365 2016 For Mac re-installation RRS feed

  • Question

  • I was downloading/updating my office 365 for Mac when something went wrong with my Internet and the update just stopped. When I tried reinstalling the update, it could not anymore. From that point on, Word and Excel became cumbersome and difficult to use. I need to reinstall Office 365 2016 For Mac on my El Capitan OS.

    How do I reinstall my Office 365 2016 For Mac  . . . .

    a. keeping all my Outlook accounts, email and contacts

    b. without disturbing my Documents in One Drive

    c. keeping all the settings in my Word, Excel, PowerPoint and Outlook.

    Thank you.

  • Hi,

    I haven't actually got the chance to do this, but we may consider the items as below:

    1. For Outlook Accounts, if they are Exchange Accounts, you don't need to backup anything, just reconfigure them in Outlook and all emails and contacts should be available.

    As far as I know, Outlook data is stored in:


    I suggest you back up them, then after the reinstallation please restore them.

    2. For your documents in OneDrive, a reinstallation of Office won't affect them.

    3. For the settings in applications, they should be stored in your user preference files, I suggest you back them up and after the installation replace the existing ones with the backups, check if this helps.

    We can refer to these two links below and learn what files we should back up. Most of them are introduced in the "remove" steps, but in your scenario you will need to back them up and restore them after the reinstallation:
