If errors occur when
testing the connection to the Administrator account, please check the following points.
To successfully log in, the following login information needs to be entered correctly:
MediaGateway connection data
Make sure that the connection data entered for the host and port are
correct. The address of the server where the Intrexx MediaGateway is
installed should be entered as the host address. If the Intrexx
MediaGateway is not on the same server as Intrexx, you need to check
wheterh the server is accessable in general, i.e. available in the
network or selectable via ping. The specified port
(default 8087) must be available and may
not be blocked, e.g. by a firewall.
The default password after installing the Intrexx MediaGateway is
"1234". If the login is not successful
with that password, it may well be that the password was change. If
you have forgotten the changed password, please contact Unitex Planet
When MediaGateway is installed successfully, a Windows service
called Intrexx MediaGateway Server is created.
Check whether the service was started and is running correctly.
Username and password
Specify the username and password of the Exchange account here.
The data are the same as those used for logging on to the Windows
The email address assigned to this account must be entered here.
Check the Exchange Server URL as well.
Use the fully-qualified domain name.
Usually, the URL starts with the protocol https://
followed by fully-qualified server name and
If the URL is correct, check whether the server is reachable from
the current computer using ping, telnet or nslookup
within a command line.
Exchange account is locked
When testing the login information, the account can be locked
after multiple failed attempts. In this casse, contact your administrator
to unlock the account once more.
To initialize the mailbox for newly created Exchange accounts,
the account needs to be accessed once via OWA or Outlook.
Outlook and OWA
Has OWA been installed on the Exchange Server and has its
functionality been started correctly. Furthermore, the virtual
directory "/exchange" must be available
in the IIS of the Exchange Server.
If this is not the case, please contact your
Exchange Administrator. For reasons concerning the system security,
accessing the virtual directory "/exchange"
can be locked or only be callable from certain computers/IP addresses.
Check the access permissions in the ISS of the Exchange Server.
2. Kerberos - Exchange 2010 / 2016
2.1 Modify EWSFindCountLimit
For security reasons, there is a limit on the maximum number of objects
that can be taken into account during a request from Exchange Server 2010.
If a request exceeds this limit, then no results will be returned.
The maximum amount is determiend in the property "EWSFindCountLimit"
of the "ThrottlingPolicy". From Exchange 2010 SP1,
"EWSFindCountLimit" in the "DefaultThrottlingPolicy"
is set to 1000 by default. If, for example, the folder Inbox contains 5000
messages and "EWSFindCountLimit" is limited to 1000,
a request to this folder will not return any results. Only when the limit is
set to at least 5000 can objects in the Inbox be requested.
The value for "EWSFindCountLimit" can either be
defined globally or for individual mailboxes. With the following commands, which
need to be performed in the Exchange Management Shell, the limit can be modified.
Identify the name of the default policy in the output
Set-ThrottlingPolicy <PolicyName> -EWSFindCountLimit 10000 (or $NULL to remove the limit)
iisreset (restarts the IISso that changes are effective immediately)
New-ThrottlingPolicy -Name "IntrexxThrottlingPolicy" -EWSFindCountLimit 10000 (or $NULL to remove the limit)
Set-Mailbox <UserName> -ThrottlingPolicy "IntrexxThrottlingPolicy"
(must be performed for each user/mailbox that access Exchange
You can only access recurring appointments if a date and time period is
specified during the request to the "Appointment"
table. To do that, you need to filter by the fields
If the "Appointment" table is sorted by start
and end date, the appointments from the Exchange 2010 / 2016 Server are always
returned in ascending order from the start data. Custom sortings in the
applications or in the browser are not supported in this case.
3. IIS Server
If you implement an IIS for your Intrexx portal, the following configurations
may be required for using the Intrexx MediaGateway.
3.1 File up- and downloads
To upload and/or download Exchange file attachments, e.g. in emails,
the file size limits may need to be adjusted. To do that, open the
Information Information Services (IIS) Manager
and adjust the ASP limit properties:
For the upload: "Maximum Requesting Entity Body Limit" (in bytes)
For the download: "Response Buffering Limit" (in bytes)
3.2 Maximum query string
In the application Exchange – Resource, it may
be necessary to extend the length of the query string when requesting
multiple overlapping resources. You can recognize this when the error
"Http Error 404: Not Found" is shown in the
browser when trying to edit overlapping resources.
In this case, proceed as follows:
Open the Information Information Services (IIS) Manager
Adjust the Feature Settings for the Request Filtering: Maximum query string (in bytes)
