Login fails in Outlook Add-In or in Spider web Access
Posted past Philip Schaffrath on ii Aug 2022 ten:54
Outcome: Authentication in the MailStore Outlook add together-in or Web Access fails.
Background: When authenticating to MailStore, various components play a role, eastward.g. the connexion to the directory service, the domain membership, client settings, and more. Since an error in one of these components tin can atomic number 82 to an error in the authentication, it is often non seen at commencement sight exactly where the fault lies. The well-nigh common potential root causes are listed here.
General reasons :
Cause 1:
The client must accept cookies from the MailStore server in order for the logon to be successful. This may be restricted by security guidelines.
You tin can check the settings under "Control Console" > "Internet Options" > "Privacy".
This error is often seen in the fact that some other login screen or the redirection to the new Web Access is displayed within Outlook.
Cause 2:
The logon fails if the hostname of the MailStore server contains an underscore.
The Internet Explorer and the Internet Explorer component in Outlook check if the hostname is a valid DNS proper name. Underscores are non allowed in DNS hostnames, therefore the Cyberspace Explorer refuses to take cookies and the login fails.
Crusade 3:
If the login is successful when using the IP address of the MailStore server, simply not when using the host proper name, in that location may be a problem in the DNS.
Cause 4:
If your company uses a HTTP-Proxy, delight make sure that users log in to MailStore Web-Access by bypassing the Proxy-Server, because there could exist problems with the Windows-Authentication / Unmarried Sign-on.
To set upward this bypassing within the Internet Explorer, please follow the next steps:
- Open the Extras in the Card from the Internet Options. If the Carte du jour is non visible, hold the Alt-fundamental.
- Open up the Connections.
- Click on LAN settings.
- Click on the Tab Advanced in the Proxy Server section.
- Enter the IP-Address or the Hostname (depending on the configuration) to the list of exceptions.
- Close all previous opened windows by pressing OK
These settings can be centrally managed by an ambassador via group policy and cannot be changed past the end user under certain conditions.
Outlook Add-In:
Cause 5:Login with Standard Authentication in the Outlook Add-In fails, when the password contains ane or more of the following characters:€ Š š Ž ž Œ œ Ÿ
The reason for this is that a different grapheme encoding is used when sending (Windows-1252) and receiving (ISO 8859-15) user credentials. To circumvent this problem, either employ Windows Authentication or change the countersign in MailStore or the directory service that MailStore is synchronized with.
Cause 6:The login fails with an error bulletin: Could not find fellow member 'OpenIDError' on object of type '#v8n'. Path 'OpenIDError', line 5, position 16.To fix this: Delight install the electric current version of the MailStore Outlook Add-in and update to the current MailStore Version.
Windows-Hallmark:
Crusade 7:
Windows authentication only works when you use Active Directory services. Other types, such as LDAP Generic or Role 365, do non back up Windows hallmark.
Even if you synchronize your mail service server with Agile Directory and then synchronize MailStore with the postal service server, Windows authentication will not work.
Cause 8:
The users synchronized in MailStore are no longer up-to-date.
In the MailStore Directory Service Settings, check if clicking on Test Settings displays all affected users as unmodified users.
If this is not the case and users are displayed under modified users or added users run the synchronization, to update those users in MailStore.
If an affected user appears nether deleted users or does not appear at all, yous must adjust your synchronization settings so that the user is captured past the synchronization procedure.
Users must be able to be captured past the synchronization process in order to make the logon permanent. If your users or their properties change more than frequently, east.yard. a user is moved to another organizational unit, you should perform the synchronization periodically and automatically. This may be east.grand. from a "Task", or for some archiving profiles before execution.
Cause nine:
If multiple MailStore users take the aforementioned LDAP DN string (Distinguished Name) in the properties, Windows authentication may not work.
If a user has been renamed within Active Directory, eastward.g. because of marriage, and the automatic deletion of users in the synchronization settings is not activated in MailStore, the user is created again under a new name. However, the LDAP DN string is the same as the one-time user. In this case, mapping between MailStore users and Active Directory users may fail, and the user can not be authenticated.
Cause 10:
To enable Windows authentication in the Outlook add-in and in Internet Explorer, the appropriate functionality must be activated in the Internet options.
To enable Windows authentication, follow these steps:
- Quit Outlook.
- Open Net Explorer, and and then click in the the Tools bill of fare on Internet Options. If the carte is non visible, printing the Alt key.
- Select the Advanced tab.
- In the Security department, activate Enable Integrated Windows Authentication.
- Restart Net Explorer.
- Now start Outlook, select the MailStore tab, open up the MailStore Outlook add-in Settings and click on theClear Cached Credentials button.
- Shut the window, and and then try again to connect the MailStore Outlook add-in to the MailStore server using Windows authentication.
These settings can be centrally managed by an ambassador via group policy and cannot be changed by the finish user under sure conditions.
Cause eleven:
To enable Windows authentication in the Outlook add together-in and in Internet Explorer, the server on which MailStore is installed must be assigned by Internet Explorer to the zone Local Intranet.
To brand this consignment, go on as follows:
- Quit Outlook.
- Open Internet Explorer, and and then click in the the Tools menu on Cyberspace Options. If the card is non visible, press the Alt fundamental.
- Select the Security tab.
- Select the Local Intranet zone.
- Select Sites -> Advanced and add the address of the MailStore server to the zone.
- Restart Internet Explorer.
- Become to the archive page.
- Click on File -> Backdrop and check whether zone Local Intranet is set up correctly.
- Kickoff Outlook.
- Select the MailStore tab, and then open up the MailStore Outlook add-in Settings and click on the Clear Cached Credentials button.
- Close the window, and then try again to connect the MailStore Outlook add-in to the MailStore server using Windows hallmark.
These settings can be centrally managed past an ambassador via group policy and cannot be changed by the end user nether certain weather.
Crusade 12:
If Windows authentication is used, the credentials are stored in the Windows Credential Director. It may be that the information stored at that place is invalid or incorrect, and logging on with the credentials will fail. In that location may be Kerberos Events with the ID xiv in the Windows Eventlog.
- Open the Run dialog by pressing the Windows-Fundamental + R .
- Enter
"rundll32 keymgr.dll, KRShowKeyMgr"without quotes and confirm with the Enter central. - Remove any entries that might be used by MailStore.
- Exercise non use the Control Panel > Logon Information Management to delete the entries because this dialog may non display incorrect entries.
- If the user does not have permission to execute the in a higher place command, open an elevated control line equally an ambassador and run the
runas /user:<domain>\<username> "rundll32 keymgr.dll,KRShowKeyMgr"command, replace the the placeholder <domain> and <username> with the values of the afflicted user.
Example
domain: testdom2
user: testuser01
command:
runas /user:testdom2\testuser01 "rundll32 keymgr.dll,KRShowKeyMgr"
Crusade xiii:
Windows authentication may apply the Kerberos mechanism. In club for this mechanism to work, all systems involved must be correctly configured. These systems are the client, the MailStore Server, and the domain controller running the Key Distribution Center (KDC).
The system time on these systems must not differ by more 5 minutes and the timezones must exist configured correctly.
Common Kerberos errors are logged in the Windows system event log.
Specific unsuccessful login attempts are logged in the Windows security effect log. Cause 14:
The error "Authentication failed on the remote side (the stream might even so be available for boosted authentication attempts)." appears when using Windows authentication. To solve this trouble unjoin the computer where MailStore Server is installed on from the domain, then join it once more.
Crusade xv:
The Windows authentication is merely successful if the MailStore Server Service is running nether the Local Organization account. This can be checked and corrected if necessary in the Windows Services or by running services.msc.
Miscellaneous:
If the Windows-hallmark is further not working, the following steps can be washed to incorporate the issue:
- Test the login with standard-authentication. Enter the username without domain and apply the domain password of the user.
- If the login with standard-authentication is working, the trouble might be between the connexion from the Client to the MailStore Server.
- If the login with standard-authentication is not working, the trouble might exist between the connection from the MailStore Server to the Active Directory.
