Logging out of Outlook on your Mac involves accessing the application’s preferences and account options. If you are searching for how to log out of outlook on mac, you likely need to remove an account, switch users, or troubleshoot a syncing issue. This guide walks you through every method, from the standard logout to removing cached data, ensuring your email stays private and your app runs smoothly.
Outlook for Mac stores your email, calendar, and contacts locally. Logging out properly prevents others from accessing your data if you share your computer. It also helps when you want to add a different account or fix persistent errors. Let’s start with the simplest approach.
How To Log Out Of Outlook On Mac
The most direct way to logout is by removing your account from the application. This process clears your credentials and stops syncing. Follow these steps carefully.
Step 1: Open Outlook Preferences
Launch Outlook on your Mac. Click on the “Outlook” menu in the top-left corner of your screen. Select “Preferences” from the dropdown list. This opens a new window with various settings.
Step 2: Navigate To Accounts
Inside the Preferences window, look for the “Accounts” icon. It usually appears under the “Personal Settings” section. Click on it to view all email accounts configured in Outlook.
Step 3: Select The Account You Want To Log Out From
You will see a list of your accounts on the left side of the Accounts window. Click on the account you wish to remove. This could be your work email, personal Outlook.com, or any other provider.
Step 4: Sign Out Or Remove The Account
Once the account is selected, look for a button labeled “Sign Out” or “Remove Account.” In newer versions of Outlook, you may see a minus (-) sign at the bottom of the list. Click it. A confirmation dialog will appear. Confirm that you want to sign out or remove the account.
After confirming, Outlook will disconnect from the server and remove your cached data for that account. Your emails, calendar events, and contacts will no longer appear in the app. You have successfully logged out.
Alternative Method: Deleting Account Data Manually
Sometimes the standard logout does not clear all local data. If you want to ensure no traces remain, you can manually delete the Outlook database files. This is useful for troubleshooting or preparing your Mac for a new user.
Step 1: Quit Outlook Completely
Make sure Outlook is not running. Click on “Outlook” in the menu bar and select “Quit Outlook.” You can also press Command + Q on your keyboard.
Step 2: Locate The Outlook Data Folder
Open Finder. Click on “Go” in the menu bar and select “Go to Folder.” Type the following path: ~/Library/Group Containers/UBF8T346G9.Office/Outlook/Outlook 15 Profiles/Main Profile/. Press Enter. This folder contains all your Outlook data.
Step 3: Delete The Account Data
Inside the Main Profile folder, you will see subfolders named “Data,” “Preferences,” and “Accounts.” To fully logout, delete the entire “Main Profile” folder. Alternatively, you can delete only the subfolder corresponding to the account you removed. Be careful: deleting this data is permanent and cannot be undone through the app.
Step 4: Restart Outlook
After deleting the folder, relaunch Outlook. The app will treat you as a new user. You will be prompted to add an account. This confirms you are fully logged out.
Logging Out Of Outlook Web Access (OWA)
If you use Outlook on the web through a browser on your Mac, the logout process is different. This method does not affect the desktop app. It only signs you out of the browser session.
Step 1: Open Your Browser
Launch Safari, Chrome, Firefox, or any browser you use for Outlook web access. Navigate to the Outlook website (outlook.com or your organization’s portal).
Step 2: Click Your Profile Icon
In the top-right corner of the Outlook web interface, you will see your profile picture or initials. Click on it. A dropdown menu appears.
Step 3: Select Sign Out
From the dropdown, choose “Sign out.” This logs you out of the web session. For added security, clear your browser cache and cookies afterward, especially on a shared computer.
Why Logging Out Matters
Logging out of Outlook on your Mac is not just about privacy. It also helps with performance. Over time, Outlook accumulates cached data from multiple accounts. Removing unused accounts frees up disk space and reduces app lag. It also prevents accidental email sends from the wrong account.
If you are selling or giving away your Mac, logging out of all accounts is essential. Your email credentials remain stored in the keychain even after removing the account from Outlook. You should also delete the keychain entries to be fully secure.
How To Clear Outlook Keychain Entries
Open the “Keychain Access” app on your Mac (found in Applications > Utilities). Search for “Outlook” in the search bar. You will see entries like “Exchange,” “Outlook Account,” or your email address. Select each entry and press the delete key. Confirm deletion. This removes stored passwords.
After clearing keychain entries, restart your Mac. Your Outlook accounts are now completely logged out with no saved credentials.
Troubleshooting Common Logout Issues
Sometimes the logout process does not work as expected. Here are common problems and fixes.
Account Not Appearing In Preferences
If you cannot see your account in the Accounts list, try restarting Outlook. If it still does not appear, the account may be configured through a different profile. Go to “Tools” > “Profiles” in Outlook and check for multiple profiles. Switch to the correct profile and try again.
Sign Out Button Is Grayed Out
A grayed out Sign Out button usually indicates the account is managed by your organization’s IT policy. In this case, you cannot logout through the app. Contact your IT admin for assistance. They may need to remove the account remotely.
Outlook Keeps Re-adding The Account
If Outlook automatically re-adds an account after you remove it, the issue is likely with your keychain or Exchange autodiscover. Delete the keychain entries as described above. Also, check if your Mac is enrolled in a device management profile that pushes accounts.
Logging Out Of Outlook For Mac Using Terminal
For advanced users, the Terminal offers a quick way to remove Outlook accounts. This method is faster but requires caution. One wrong command can corrupt your system.
Step 1: Open Terminal
Go to Applications > Utilities > Terminal. Type the following command to list all Outlook accounts: defaults read com.microsoft.Outlook. This shows a long list of settings. Look for the account name you want to remove.
Step 2: Delete The Account Plist
Outlook stores account data in a property list file. Navigate to ~/Library/Preferences/ and find files named “com.microsoft.Outlook.plist” or similar. Delete the plist file after backing it up. Restart Outlook. The account will be gone.
Using Terminal is not recommended for beginners. Stick to the Preferences method if you are unsure.
What Happens After You Log Out
After logging out, Outlook stops syncing with the server. Your local data remains on your Mac until you delete it. If you log back in with the same account, Outlook will re-download your emails and calendar. This can take time depending on your mailbox size.
If you removed the account permanently, you will need to add it again from scratch. All offline data from that account is no longer accessible through Outlook. However, the data may still exist in the Outlook database folder until you delete it manually.
How To Log Out Of Outlook On Mac For Exchange Accounts
Exchange accounts are common in corporate environments. Logging out of an Exchange account is similar to removing a regular account, but there are extra steps to fully disconnect from the server.
Step 1: Disable Cached Exchange Mode
Before removing the account, go to Outlook Preferences > Accounts. Select the Exchange account. Uncheck “Use Cached Exchange Mode.” This forces Outlook to sync directly with the server. Then remove the account as usual.
Step 2: Remove Exchange Server Certificate
If you want to be extra thorough, remove the Exchange server certificate from your keychain. Open Keychain Access, search for your Exchange server name, and delete the certificate. This prevents Outlook from automatically reconnecting.
