Outlook 2016 for Mac; In this article Summary. You can set Outlook 2016 for Mac to delay trying to renew a Kerberos ticket. This will prevent Outlook from prompting for credentials during the defined period. When Outlook is set with the delay and a Kerberos ticket is renewed, the program will use the new ticket and try to connect online. To fix this issue, update Outlook 2016 for Mac to version 15.23 or a later version. Then, disable the preview feature for encrypted email messages by running a command in Terminal. To do this, follow these steps. Step 1: Check the Outlook for Mac version number. On the Outlook menu, click About Outlook. View the version number that is listed.
Learning has never been so easy!
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'.
Outlook For Macintosh
Step 2: Clear old items relating to Exchange/MS login in the keychain
According to a Microsoft Representative, the best option here is: Move microsoft office 365 from windows to mac.
Office microsoft mac free trial. Make sure you quit Outlook and other Office apps.
Download Microsoft Outlook For Mac
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
