UCCX E-Mail MAPI Connection Limit

Wanted to poll the userbase out there utilizing UCCX E-Mail. My question is did you complete the Exchange registry steps to set the MAPI session limit to 2,400 connections per user?
If not, what is your currently set at? Do you experience any issues?

Hi,
no, actually it is just a simple SMTP session without any queuing capabilities.
You have two options:
1. (easy) set up a small SMTP server with queuing capabilities someplace near the UCCX server,
2. (challenging) before using the Send Email step, make a copy of all emails, for instance, in a database, and make the same script delete this row when it exits on the Successful branch of the Send Email step. If for any reason the send fails, the email remains in the database and you can use any Python/Perl/**your favorite language here** script to periodically check for these rows and send them.

The TFO accelerator is overloaded (connection limit) and MAPI problems

Hi All!
Problem description:
When MAPI acceleration (exchange/outlook) is Active in our WAAS environment, the remote site users randomly lose connection to the Exchange server (on hub site), if I disable the MAPI acceleration everything works ok. so right now we are running with MAPI accelearation Disabled
I can see that we often get max_conn_reject The TFO accelerator is overloaded (connection limit), we haven't done any adjustments to the default configuration.
The environment is one Hubsite with two remote sites.
[Hub Site] 34mbit
HW=OE674
SW=4.1.5
inline
Enterprise Lic
[Remote Site1] 4 mbit
HW=OE474
SW=4.1.5
inline
Enterprise Lic
[Remote Site2] 4mbit
HW=OE474
SW=4.1.5
inline
Enterprise Lic
So the question is how to solve this?!

I had a feeling that you might have alot of computer remotely.
One of the main factors in sizing a WAAS soluiton is to keep in mind the number of TCP connections that a single WAE can optimize.
We limit the device on optimized TCP connections.After you hit the limit the device will go into the overload state that you mentioned.
274 - 200 connections
474 - 400 connections.
Typically from a sizing a single workstation would be sized from 7-10 TCP connections.
The 2nd factor in sizing is bandwidth - WAAS doesn't limit bandwidth but this is recommended for the CPU throughput.
274 - 2 Megs
474 - 4 Megs
The 3rd factor is redundancy,. HA, etc.
Thanks,
Eric
remember if this answrs your questions, please mark as answered and with a 5.

How can I script out automatic mail profile connection to Exchange 2013

We use a program called Desktop Authority 9.1 that is a fully featured kixstart based logon user profile customization tool. It does a full gamout of things like map drives, folder redirection, import registry edits, run silent application installers,
and of course create the Outlook profile.
There's no issues with this tool creating an outlook profile internally to mail.domain.com, and even detecting laptops and configuring it for outlook anywhere to webm.domain.com and cached mode.
Issue I'm having is trying to roll out Exchange 2013. This tool simply does not seem to create the mail profile. On a test computer I have the hosts file pointed to the new 2013 server from these names: webm, mail, autodiscover. At log
on I simply get an error "The name cannot be resolved. The name cannot be matched to a name in the address list." When you click OK you get a little confusing dialog box with the exchange server name: mail and the mailbox: windows
user ID.
So I tried to do this manually in the Mail (32-bit) control panel applet. It doesnt matter if I put in mail, mail.domain.com, webm, webm.domain.com, email (the netbios name of exchange 2013), etc.. I get the same error. I went into More settings
> Connection > connect to microsoft exchange using HTTP and in the proxy settings I have webm.domain.com, connect SSL Only, only connect to proxy servers that have the name: msstd:webm.domain.com, and the rest is checked and NTLM Authentication is checked.
I simply CANNOT manually create an outlook profile at all. I can surely delete this one, start outlook, click next through the wizard taking all the default options and get Outlook configured that way (via Autodiscover service), but I need a way to
do it manually so I can have Desktop Authority do it manually. Why? Two major reasons:
1. If our end users are greeted with an Outlook startup wizard every time they go to a different computer, and have to click next through it, our help desk is going to be overwhelmed with "what is this outlook startup wizzard?" questions.
2. Desktop Authority also attaches additional mailboxes. We need the outlook profile passed through DA's scripting so different users departmental voice mailboxes are attached in their outlook. IE) Mailbox VM_FAX_Accounting is attached
to all of the accounting associates Outlook.

Ok I found another way to get autodiscover to work..
In Group Policy go to User Configuration > Administrative Templates > Microsoft Office 2010 (and 2013 in my case) > Miscellaneous > Suppress recommended settings dialog > Change to ENABLED.
Now go to User Configuration > Administrative Templates > Microsoft Outlook 2010 (and 2013 in my case) > Account Settings > Exchange > Automatically configure profile based on Active Directory Primary SMTP address > Change to ENABLED.
Now for the shared mailboxes, I guess when we plan to migrate a department, their shared mailbox MUST be migrated from 2007 to 2013 on the same evening, and then we must go into that shared mailbox and ensure each individual user has "Full access
permissions" to it.
Now in Desktop Authority we publish this reg file:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\AutoDiscover\RedirectServers]
"autodiscover-s.outlook.com"=hex(0):
"autodiscover.outlook.com"=hex(0):
"autodiscover.domain.com"=""
[HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\AutoDiscover\RedirectServers]
"autodiscover-s.outlook.com"=hex(0):
"autodiscover.outlook.com"=hex(0):
"autodiscover.domain.com"=""
[HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\AutoDiscover\RedirectServers]
"autodiscover-s.outlook.com"=hex(0):
"autodiscover.outlook.com"=hex(0):
"autodiscover.domain.com"=""
Why that? Well it turns out further testing when I added full permission to a new 2013 test shared mailbox, yet another nag screen was presented in Outlook which states "Allow this website to configure [email protected] server settings? autodiscover.domain.com/autodiscover/autodiscover.xml
- Your account was redirected to this website for settings. You should only allow settings from sources you know and trust. (Allow) (Cancel). If end users see this, you can bet our helpdesk calls will be out of control. We undergo security
awareness training and they will question ANYTHING resulting in redirect or dialog boxes asking about trust, and really that's a good thing.
That registry should I think handle Outlook 2007, 2010, 2013, and we will just have to maintain it for future versions.
We maybe have, I dont know less than 5 Outlook 2007 installs and they are on spare laptops, so If I want to cover it all I just have to download the Office 2007 ADMX templates for Group Policy so I can change those two settings above as well.
The other way I thought was to use powershell and script something out to pull from Exchange the GUID, append the @domain.com and put that into a variable that our Desktop Authority application can plug in at startup. But thats a little too much custom
programming whereas I think using GPO's and documented registry keys may be a better fit.
I just have to do testing to figure out what's going to happen to the users profile if it already exists on 2007, then its migrated to 2013. Will it be deleted? Will they lose all of their signatures? I know for many on network
PC's they will be going from direct mapi connection to Cached mode. Is that a good thing? I would imagine less load on the server and network once the mail is downloaded.
We would plan on a slow migration on a departmental basis. Luckily our departments have their own user OU's so applying this group policy can be done in the same manor.

Opening multiple reports in Crystal Reports for VS causes database connect limit to be reached. Seems to be no way to force Crystal Reports to close database connection (other than exiting application)

I am working on upgrading an application that has been in use for many years. The application is written in VB6 and I have been tasked with upgrading the current application to Crystal Reports for Visual Studio. I am using Crystal Reports for VS Version 13.0.12.1494. The system's database is a Sybase SQL Anywhere 16 database with an ODBC connection using integrated login. Each of the reports has the database connection set up from within the report. There is only once database server, so each of the reports are pointing to the same DB. The database server is currently installed as a "Personal Server" with a limit of 10 connections.
I have implemented the CR viewer as part of a COM-callable wrapper that exposes a COM interface for VB6 to interact with. Inside of my viewer component is a Winform that embeds the Crystal's Report viewer. The COM interface basically maps the basic Crystal apis to methods that the VB6 can call (i.e., Load Report, Set Field Text, Update SQL Query, etc). This architecture is working as designed and the reports are displaying correctly and responding correctly to changes in queries, etc.
The issue is that after I open 9 reports, the tenth one will respond with an error indicating that the database connection limit has been reached. The database connections used by the reports aren't released until after the application is closed. The application is designed for a secure environment that prohibits the non-administrative user from accessing the systems desktop, so asking the user tor restart the application after 10 reports isn't a viable option.
I have checked and database connection pooling is turned off for the SQL Anywhere 16 driver.
I have been digging on this for a few days and have tried adding code in the FormClosed event to close and dispose of the Report Document as follows:
ReportDocument reportDoc= (ReportDocument) crystalReportViewer1.ReportSource;
reportDoc.Close();
reportDoc.Dispose();
GC.Collect();       // Force garbage collection on disposed items
I have also tried the following (as well as maybe 20 or so other permutations) trying to fix the issue with no success.
ReportDocument reportDoc= (ReportDocument) crystalReportViewer1.ReportSource;
foreach (Table table in reportDoc.Database.Tables)
     table.Dispose();
crystalReportViewer1.ReportSource = null;
reportDoc.Database.Dispose();
reportDoc.Close();
reportDoc.Dispose();
reportDoc = (ReportDocument)crystalReportViewer1.ReportSource;
GC.Collect();       // Force garabe collection on disposed items
Any ideas or suggestions would be greatly appreciated. I have been pulling my hair out on this one!

Hi Ludek,
Thanks so much for the quick reply. Unfortunately I did not have time to work on the reporting project Friday afternoon, but did a quick test this morning with some interesting results. I'm hoping if I describe what I'm doing, you can show me the error of my ways. This is really my first major undertaking with Crystal Reports.
If I simply load the report, then close and dispose, I don't hit the limit of 10 files. Note that I do not logon manually in my code as the logon parameters are all defined within the reports themselves. The logon happens when you actually view the report. Loading the report doesn't seem to actually log in to the DB.
What I did was create a very simple form with a single button that creates the WinForm class which contains the Crystal Viewer. It then loads the report, sets the ReportSource property on the CrystalReportsViewer object contained in the WInForm and shows the report. The report does show correctly, until the 10 reports limit is reached.
The relevant code is shown below. More than I wanted to post, but i want to be as complete and unambiguous as possible.
This code displays the same behavior as my earlier post (after 10 reports we are unable to create another connection to the DB).
// Initial Form that simply has a button
public partial class SlectReport : form
        public SelectReport()
            InitializeComponent();
        private void button1_Click(object sender, EventArgs e)
            ReportDocument rd = new ReportDocument();
            ReportForm report = new ReportForm();
            try
                rd.Load(@"Test.rpt");
                report.ReportSource = rd;
                report.Show();
         catch (Exception ex)
              MessageBox.Show(ex.Message);
// The WinForm containing the Crystal Reports Viewer
    public partial class ReportForm : Form
        public ReportForm()
            InitializeComponent();
        private void Form1_Load(object sender, EventArgs e)
            this.crystalReportViewer1.RefreshReport();
            this.FormClosed += new FormClosedEventHandler(ReportForm_FormClosed);
        void ReportForm_FormClosed(object sender, FormClosedEventArgs e)
            ReportDocument rd;
            rd = (ReportDocument)crystalReportViewer1.ReportSource;
            rd.Close();
            rd.Dispose();
        public object ReportSource
            set { crystalReportViewer1.ReportSource = value; }
Again, any guidance would be greatly appreciated.

ACE connection limit and remote TCP security scans

We are currently running remote TCP security scans on our networks and are running into a major problem where when the scans are taking place the ACE connection resource usage sky rockets and easily reaches the maximum 4 million connections. This means that anyone can run a simple TCP scan and take down our ACE by maxing the connection limit. We have the following parameter-map applied to all of our policies but it does not help to clear the connection count on the ACE in a reasonable amount of time. parameter-map type connection CONNECTION_TIMEOUT set timeout inactivity 300 set tcp timeout half-closed 60 I should note that we do have normalization turned off because it causes way more problems then it's worth (no resolution with TAC). Does anyone have an tips on how to accommodate security scan's on networks behind the ACE while not saturating the connection count limit?

For vips, this particular context only has one class C applied to a class-map. Not all IP's are in use but regardless the ACE creates connections for those as well. I've set the timeout inactivity to 120 seconds and I still see connections from the remote scanning host idling well over 45mins for connections destined to the vip's. Is turning on normalization my only option? I know there are others who have turned off normalization due to performance and connectivity issues so there must be other ways around this. Thanks for your help.

BYE Connection limit reached

Hi, Everyone
My customer's site use Webmail (using JavaMail API and customer made webmail module) connect IMAP.
Rescently, I can see the following IMAP log.
2006/11/15 16:51:38 <E> <com.daou.winip.mail.manage.UserLoginManager> javax.mail.MessagingException: * BYE Connection limit reached
for your IP address;
nested exception is:
com.sun.mail.iap.ConnectionException: * BYE Connection limit reached for your IP address
As a result of this, login is very slow and IMAP connection is disconnected.
Anyone who experienced this, plz let me know how to solve this problem.

My mail provider has further indicated that even during part of the period I am idle and not opening any of my folders in mail App, sometimes the app is hitting the IMAP mail server. This is not an expected behaviour he is saying.
It perhaps implies that the iOS mail App is having bug.

At least, is it possible to choose what email account, the arrival of a message launch a notification.
When running more than a dozen e-mail accounts, it may be appropriate to display only the notifications of one or two major accounts.

Too many connections - limit of 150 reached

We ran into a situation where a program (written in PHP, running under Apache) was spawned via crontab every 30 seconds for test purposes. It connected to the database but did not disconnect.
Net result: Once the program had been started 150 times, the database refused any more connections. No valid users could connect. I couldn't even connect from the oracle privileged account.
Item 1: The process will be modified to explicitly close its connection when done, rather than trusting the job to default behavior of PHP. So, hopefully, we will not run into this a second time.
Item 2: But if we do have this problem again, I need to know how to intervene when the connection limit has been reached. I was not able to connect myself and therefore could not query v$process or related tables to gather any information. I could kill the various (useless) listener processes at the unix command line, but it still took time for Oracle to sense the dead process and mop up. How to accomplish this quickly?
Item 3: I can probably set up the rogue process to login as a different user and then set a resource profile for that user including timeouts. Any suggestions on values for that resource profile?
Item 4: Is there a way to reserve a listener connection for a privileged account such as the DBA?
Thanks for any guidance.

Thanks for the friendly reply.
What worried me was that I had to wait for the useless connections to clear, before I could connect and see what the sessions were. Yes, Oracle had to roll back any uncommitted work, and there's no way to speed that up, but I wanted to see that processes from inside of Oracle (connected) not from outside.
Is it possible to configure the listener to "reserve" one connection for a privileged account? No.
It is not the listener's responsibility. In fact, it is not even the listener's responsibility to maintain existing connections. Once the listener services the connection request, it is totally out of the picture. You can even kill the listener, and any existing connections will continue on. It's like being introduced to someone at a party. Once you are introduced to someone (by The Listener), you carry on your conversation with that person directly, not through the person (The Listener) who introduced you.

Can't get my mail to connect

Hi, just ran into a problem with my mail today. I've never had a problem with my POP account before. Earlier today I opened up Entourage to take a look at it ( I never use it but was just doing a little exploring). After it opened it gave me a prompt - something about changing the keychains - and I clicked OK. But immediately after this I had problems receiving mail in both Mail and Entourage. First I received this pop-up from Mail:
The POP server “oooooo” rejected the password for user “oooooo”
Please re-enter your password, or cancel.
I re-enter my password and then nothing. After several attempts of this Mail stops connecting to the server.
Anybody know what to do?
Thanks

Hi nipponmark.
Open /Applications/Utilities/Keychain Access, choose Keychain First Aid from the application menu, and proceed to repair the keychain. If that doesn’t work, you may try removing the password entry from the keychain and letting Mail create it again the next time it asks for it.
The fact that Mail appears to be trying to connect to the server on port 0 indicates that there could be something wrong with the network or with your network settings.
Go to Apple Menu > System Preferences > Network, choose Network Port Configurations from the Show popup menu, and make sure that the configuration used to connect to Internet appears at the top of the list. Leave checked (enabled) only the port configuration needed to connect to Internet and Built-in Ethernet (in that order if not the same), uncheck (disable) the rest of network port configurations and see whether that helps — if it doesn’t, turn ON again the ones you want enabled.
Now, from the System Preferences > Network > Show popup menu, choose the network interface used to connect to Internet, go to the Proxies section, and try disabling the SOCKS Proxy if it’s enabled.
Try using a different method to connect to Internet, if possible, or connecting the computer to Internet as directly as possible (i.e. bypassing any routers that might be present, using an ethernet cable instead of wireless, etc.), or shutting down both the computer and the router/modem used to connect to Internet, restarting, and see whether that makes a difference.

Mail server connection problem

Mail in my macbook pro from time to time interrupts mail server connection (mac mini server). As i discoveredn turn off turn on wi fi reestablish connection. Does anybody know how to solve the problem?

Check the server log for details on the local mail server activity. These mail server logs are available via Console.app or via Server.app.
To verify local DNS services — a very common cause of problems — launch Terminal.app and issue the following harmless, diagnostic command:
sudo changeip -checkhostname
You'll need to enter an administrative password for the sudo, might then see a one-time message describing the use of sudo, then some server network configuration information if and as available, and finally an indication that there are no changes required, or that there are DNS or network or other issues.
You'll need to be referencing your local DNS server — you cannot reference your ISP DNS servers, nor any other off-LAN DNS servers here — in your clients. This either by explicit configuration in the clients, or via the DNS server settings distributed by your local DHCP server. Do not reference both local and off-LAN DNS servers, either — just your own local DNS server(s) on your local NAT'd network. No off-LAN off-NAT'd-network DNS servers can provide valid DNS translations for your local LAN, and SMTP traffic is based on properly configured DNS.

I have tried it with both "pop3" and "imap" in
Store store = session.getStore("pop3");
for the company email but it does not work.
Is this a problem with company security? Maybe firewall/proxy error? If so how do I get around it?
2. Also, when I am in the office (LAN used to connect to Internet) I cannot even get a connection to the ISP account - similar problem or different?
Any thoughts and help most appreciated.
Thanks in advance,
Mark

It could be that the mail server is not accepting connections from the machine you are on. Have you tried using Outlook Express or the Netscape email client to connect to the server/account from the machine that is getting the failure?

Javax.mail.MessagingException: Connection refused: connect on localhost

After entering the input details in my html file, i get the error- "javax.mail.MessagingException: Connection refused: connect; nested exception is: java.net.ConnectException: Connection refused: connect " .
can anybody help me regarding in solving error.
Thanks.

First, you're using a very old version of JavaMail. Please upgrade. Some of the properties you're setting aren't supported in that old version.
Second, you don't need the socket factory properties, get rid of them.
Finally, it looks like you're trying to connect on port 143 using SSL. Port 143 is the non-SSL port. That's probably not going to work. Still, it looks like something is refusing to let you connect at all. If you really can telnet from the same machine your program is running on to the same server machine on port 143, then you probably have some sort of firewall that's preventing your program from connecting. Please post the entire debug output if it still fails after correcting the problems above. (Move the setDebug call to before the getStore call.)
