• Microsoft Outlook On Mac Keeps Asking For Password Windows 7

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. Should i buy microsoft office 2016 for mac.

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

It is evident from the above that Keychain Access is an important part of the Mac operating system. It keeps all the password in macOS. However, due to the creation of multiple tokens of the same kind in Keychain, Microsoft Outlook 2016 for Mac keep asking for password. Feb 03, 2019  I have outlook email on PC, Mac, iPhone and iPad. I have other email services too and these other services, on the same devices, using the same email client (Thunderbird and Apple Mail) work 100%. Outlook email keeps asking for the password. Over and over. Mostly this happens on.

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

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

After you or your Mac administrator resets the password of your macOS user account, your Mac might ask you to update your keychain password or enter the password of your login keychain. It might also tell you that the system was unable to unlock your login keychain. That's because your login keychain is still using your old password.

If you don't know your old password

If you don't know your old password, the solution is to create a new login keychain.

If you know your old password

If you know your old password, use that password to update your existing login keychain:

1. Open the Keychain Access app, which is in the the Utilities folder of your Applications folder.
2. From the list of keychains on the left side of the window, select 'login.'
3. From the Edit menu in the menu bar, choose “Change Password for Keychain 'login.'”
4. Enter the old password of your user account in the Current Password field. This is the password you were using before the password was reset.
5. Enter the new password of your user account in the New Password field. This is the password you're now using to log in to your Mac. Enter the same password in the Verify field.
   
6. Click OK when done, then quit Keychain Access.
