Office 2016 For Mac Unable To Activate

Re: Unable to Activate Office 365 Office 2016 proplus on Windows 7 SP1 machine I would suggest one of two ways, as I have had the same issue. Get off your network.

Learning has never been so easy!

This is the video of how to download, install and activate MS Office 2016 on MAC OS X. Just have a look on it and try this experiment on your MAC and if you. Outlook 2016 for Mac integrates with a variety of different email clients, including Exchange, Office 365, Outlook.com, Hotmail, iCloud, Google, and Yahoo! This means that when you add all of your email accounts to Outlook, you can compose new messages and read and respond to email messages from one application—no need to open multiple email. This is a domain machine with Windows 10 Pro 64-bit and Office 2016 Standard volume license version installed, and was successfully activated via a MAK key. How can I keep the wizard from running for all users? The machine is a new ThinkPad, that originally had a trial version of Office 2016 on it.

So, I was having this BRUTALLY annoying issue on my macs (when I work from home, I work on my mac) where, every time I launched Outlook 2016, I would be prompted to login with my credentials... Just super annoying and unnecessary.

Theres a ton of documentation on 'how to fix this' but a lot of it misses an important step (also, a facepalm step).

6 Steps total

Step 1: Open the Keychain

Theres a bunch of ways to do it, but ultimately, the easiest way is to press CMD+Space, to open spotlight, then search 'Keychain Access'.

Step 2: Clear old items relating to Exchange/MS login in the keychain

According to a Microsoft Representative, the best option here is:

Make sure you quit Outlook and other Office apps.

Search 'Exchange' under Login --> All Items and delete everything (NOT EVERYTHING - take a look and make sure you're only deleting entries that are in some way related to Microsoft)

Search 'Office' and delete everything
Search 'ADAL' and delete everything

Step 3: Open Outlook & Login

Yea, I know, we're trying to fix this - but you have to log in this ONE more time...

Step 4: Open Outlook Preferences from the menu

How To Activate Office 365 On Mac

Click Outlook -> Preferences in the menu bar

Step 5: Open Accounts

Open the Accounts Section...

Step 6: Finally... Add your password

Seriously - this is critical! Add your password in the password field for the account in question, then close the preferences window.

NOW - when you restart Outlook you SHOULD NOT have to login!

While this isn't the most difficult or pressing issue in the world, it most definitely is annoying! I hope this guide helps some folks!

  Thanks for posting, but the login box still appears. A question -- when I searched Exchange, should I delete the Private Exchange Key (two of them) and Public Exchange Key (also two files)?

  still not working for me. I have 3 office 365 accounts, and every time I should enter the password 3 times for each account. It is really annoying

  A couple of steps we added to our recipe to workaround this longstanding issue:

  - Open Keychain Access > View > Show Invisible Items
  - After deleting entries in Keychain related to office, exchange, and adal > restart computer.
  - In Keychain > lock the login entry.
  - Open Outlook > input password to allow access to Keychain again
  - Continue with steps to input password into the password textbox under Tools > Accounts > mailbox(es) having issues
  - Restart Outlook
