  • Steps to Fix Outlook 2011 For Mac Keeps Asking Password of Office 365 Account. If the Keychain Access program is corrupted, then whenever the Outlook user is trying to connect with O365 on Mac platform, the password problem arises. As a result, Outlook 2016 for Mac keeps asking for password of Office 365 account.
  • How to fix Outlook deleting all the messages from the server when it shouldn’t, or downloading the same messages repeatedly. Certain versions of Outlook 2016 have a bug that causes this behavior with POP3 connections. A Microsoft page about this bug explains in more detail what happens and how to fix it.
  • Outlook 2016 keep getting prompted for 'Sign in with your Google account' every few. Enabled 2 step verification with an Outlook app password in my gmail but I'm not sure if this is necessary to fix the pop up issue. Hope this works for you all:-).

Windows 10 - Go to Control Panel in search box type'mail'. Click on Microsoft Outlook 2016 and open general tab add new profile. Then when you open Outlook go account.
  • Ahhh microsoft, you have done it again! For mac users, go to toolsaccounts and under server information be sure that the user name is your complete email address. Then close and restart Outlook. This worked for me, after much frustration with popups repeatedly telling me that i was signing in with the wrong account.

May 20, 2019  In Microsoft Outlook 2016 for Mac running on Mac OS X Yosemite (10.10) or later versions, you cannot set Outlook as the default application. In Outlook Preferences, under General, you enable the Make Outlook the default application for e-mail, calendar, and contacts option.However, when you check the general preferences again, this option is not enabled.

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'.

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!

Select Yes.The install begins.Your install is finished when you see the phrase, 'You're all set! There could be an issue with your account. Office is installed now' and an animation plays to show you where to find Office applications on your computer. Select from above and review the solutions under Account questions.Install Office.Depending on your browser, select Run (in Edge or Internet Explorer), Setup (in Chrome), or Save File (in Firefox).If you see the User Account Control prompt that says, Do you want to allow this app to make changes to your device? Microsoft office mac family center.

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!

    Tried and still not working for me. Box will not go away. :(

    Microsoft user data folder mac office 365. Mar 19, 2020  I just upgraded from Office 2011 for the Mac to office 2016 (via an office 365 subscription). Can I delete the old 'microsoft user data' folder in my documents folder. My understanding is that office 2016 doesn't need it. Since I didn't use Outlook, the folder is small, but it is still clutter I'd like to get rid of if not needed. The first time that you use Office, a folder named Microsoft User Data is created in the Documents folder provided by the Mac OS. The Microsoft User Data folder contains an Office 2011 Identities folder that stores the Office database for each identity in its own folder. You can move the folder for an identity.

    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
