When working with Microsoft Outlook on your Windows 11/10 PC, you receive a server message A specified logon session does not exist; It may already have been terminated for long periods, then this post may help you. This message can also be seen while trying to log in to your OneDrive account.
Specified logon session does not exist error in Outlook
If Microsoft Outlook displays an error message – A specified logon session does not exist, It may already have been terminated, then try these suggestions. This usually happens after a domain migration, if Outlook doesn’t accept your account credentials, but keeps prompting you with the error message.
- Delete all files from the Accounts folder
- Create a new Registry key ‘DisableADALatopWAMOverride’
- Create a new Registry key ‘EnableADAL’.
The method requires you to make changes to the Registry Editor entries. Please note that serious problems can occur if you make changes incorrectly, so back up your Registry first.
1] Delete all files from the Accounts folder
Navigate to the following Explorer location:
%LOCALAPPDATA%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\AC
Here if you see \TokenBroker\Accounts folder then delete all the contents of the Accounts folder.
Restart your PC and re-create an Outlook profile.
Did this help? If not, then proceed.
2] Create a new Registry key DisableADALatopWAMOverride
Open the Registry Editor and navigate to the following path address –
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity
Switch to the right-panel window and create a new key with the following name (DWORD 32-Bit value) DisableADALatopWAMOverride.
Double-click on the value to change its Value Data from ‘0’ to ‘1’.
If this helps, great, else create another key.
3] Create a new Registry key EnableADAL
Follow the same path address and create another key bearing the following name EnableADAL. As earlier, this key too is a DWORD 32-Bit value.
When created, double-click the entry and set its value to ‘0’.
Finally, restart Windows and attempt to create a new Outlook profile again to see if the problem is resolved.
