Outlook – Cannot add to the server Junk E-mail Lists

Friday, October 9th, 2015


Outlook says it Cannot add to the server Junk E-mail Lists

Microsoft Outlook Junk E-mail List Full

•Cannot add to the server Junk E-mail Lists, you are over the size allowed on the server. The Junk E-mail Filter on the server will be disabled until your Junk E-mail Lists have been reduced to the size allowed by the server. Would you like to manage your Junk E-mail Lists now?


If there are many cumulative entries in the Safe Senders, Blocked Senders and Safe Recipients lists, you can probably isolate this problem to a small number of mailboxes. For example, if only a few users encounter the errors that are described in the “Symptoms” section, you should examine the Safe Senders, Blocked Senders, and Safe Recipients lists in Outlook to determine whether there is a large number of entries in the lists (in total).

If you have narrowed the problem to being caused by a large number of items in these lists, you can configure a larger limit by using the Max Extended Rule Size registry value on your Exchange server. This solution can be used on servers that are running Exchange Server 2003, Exchange Server 2007, and Exchange Server 2010.

Key: HKLM\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
Value: Max Extended Rule Size
Data: an integer specifying the maximum size, in bytes, you want to allow for the junk e-mail rule

The value that you enter in the registry is interpreted as the maximum rule size in bytes. Therefore, if you want to specify a limit that is larger than the default 510 KB, you must enter a value that’s greater than 522240 (decimal).

Note You must restart the Microsoft Exchange Information Store service for this change to take effect.

This change affects all mailboxes that are located on the Exchange server on which this registry change is performed.

How to suppress the AutoDiscover mismatch warning in Outlook 2007, Outlook 2010, and Outlook 2013

Monday, March 23rd, 2015


The name on the security certificate is invalid or does not match the name of the site.

The name on the security certificate is invalid or does not match the name of the site.

Every time I open Outlook, I get this warning, about 30 seconds after Outlook opens.  I have 3 accounts so I get this 3 times.  I am well aware that the autodiscover record for my domain does not appear on my SSL cert on the Exchange server and I don’t care.  I just want the warning to go away.

Microsoft has  long article about this topic but it doesn’t help at all.  Specifically, I tried Method 4: Configure Outlook to allow the connection to the mismatched domain name. I know that adding a new name to my cert would solve the problem but that was not an option.

Then I found this article which looked really promising.  But it didn’t solve my problem either.  I added the registry entries but the autodiscover cert warning continued to pop up every time Outlook was opened.

Then I found this article which takes a different approach.  They actually understood my problem which is that I have a large number of domains and I can’t add them all to the cert.  But the suggestion to set up a new webserver to forward requests seemed overly complicated, although I’m sure it would have worked.

Solution:  Use SRV Records to forward Autodiscover Requests

This article explains the details.

Key points:

Use the following parameters to create a new SRV record:

Service: _autodiscover
Protocol: _tcp
Name: autodiscover
Port Number: 443
Host: autodiscover.contoso.com  (the url of a valid domain that is on your SSL Cert)

You’ll need to set this up in your Internal and External DNS records.

Outlook Won’t Connect to Office 365 or Exchange 2013

Tuesday, December 30th, 2014


Trying to set up Outlook 2007 or Outlook 2010 with Office 365 account and it won’t connect.  It still works fine on my old computer but I can’t log in and complete the account setup with my new computer.


Follow the instructions here to install the configuration software.  PDF is also attached in case that site goes away.


You would need the following patches:

  • KB2687404 from the November 2012 public update

I would also install the Microsoft Sign-in Assistant (http://www.microsoft.com/en-us/download/details.aspx?id=28177) also to be on the safe side.

Outlook 2007 Index – How to Speed it Up

Thursday, June 13th, 2013
I found myself in a situation where i wanted to increase the priority of the indexing process performed by the Windows Search service in Windows 7…. to cut a long story short I decided to rebuild the index.
It did most of the documents fairly quickly, but Outlook indexing was taking forever. I pretty much always have Outlook open which makes the indexing process proceed slowly to avoid causing problems for the user while indexing takes place.

The problem with that is that you can’t search your email properly until the indexing is complete… Outlook warns that you’re unlikely to get proper search results and can tell you how many items are left to index, in my case around 25000.

In earlier versions of Windows it was possible to easily tweak the registry in order to stop the indexing service from slowing down when it detected user activity.
Things have changed a bit in Windows 7. For a start the likely candidate registry key, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Search\Gathering Manager, has a set of permissions that make it obvious that you really shouldn’t be playing around with these registry entries.
You can work around the permissions issues, by impersonating the user TrustedInstaller, using a nifty piece of software called devxexec, however there is little point in doing so.
Modifying the DisableBackOff and DisableBackOffOnUser entries under the Gathering Manager key made no discernible difference to the indexing speed and the Indexing Options dialog continues to display a message indicating that it is indexing at reduced speed due to user activity.

After much googling on the topic I was not left with any clear answers, however some posts had mentioned using Group Policies on domain-linked computers in order to achieve the same result.

Start > Run > gpedit.msc

This will open the Local Group Policy Editor. Looking under

Computer Configuration > Administrative Templates > Windows Components > Search

you can see there is an entry called Disable indexer backoff. Double click the entry and choose Enable, then click OK.

After a restart I opened the Indexing Options dialog and once the Windows Search service had started up it began indexing. I opened Outlook and a few other programs and it appears that it no longer slows down.

Your Outlook contains thousands of contacts and many of them are duplicates.

Unable to Add to the server junk e-mail lists – Exchange 2007

Friday, July 15th, 2011


This message pops up frequently while using Outlook 2007 or Outlook 2010 (probably any version).

Unable to add to the server junk e-mail lists, you are over the size allowed on the server. The Junk e-mail filter on the server will be disabled until your junk email lists have been reduced to the size allowed on the server

Unable to add to the server junk e-mail lists, you are over the size allowed on the server. The Junk e-mail filter on the server will be disabled until your junk email lists have been reduced to the size allowed on the server

More Information:

The problem occurs in either Cached Mode or Online Mode.

The Safe Senders, Safe Recipients, and Blocked Senders lists contain zero items.

The boxes are checked to Trust email from my Contacts and Automatically add People that I email.

Safe Senders List is Blank

Safe Senders List is Blank

If I add an entry to any of the three lists and click apply, the same error message appears stating that the server list is full.  If I log into OWA and check the list, the entry I just added will not appear even though it still appears in the Outlook list.

If I add an entry to any of the three lists from within OWA, the item will appear in Outlook.

If I look at my Outlook Contacts list, I see over 33,000 items and most of them are duplicates of garbage.

33,000 Garbage Contacts from a series of bad syncs

33,000 Garbage Contacts from a series of bad syncs


Uncheck the box to stop trusting your contacts list.  This was adding 33,000 entries to your safe senders list which is over the limit.

Clean up your messy contacts list and then check the box again.
