How can I prevent Outlook from adding junk e-mail lists to the server?
The option "Also trust e-mail from my Contacts" is what makes the "Safe Senders" list exceed the total limit.
You can try changing the limit of the junk e-mail lists, listed at the bottom of the page.
By default, you have the following limit on the total size of the junk e-mail lists:
- Exchange: 512 kb (cumulative for all lists combined)
- POP3/IMAP: none
Therefore, if you are using these lists extensively with an Exchange mailbox, you might hit the 512 KB limit.
Registry key:
HKLM\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
Value: Max Extended Rule Size
Type: DWORD
Data: maximum size, in bytes, you want to allow for the junk e-mail rule
As you can see, "Max Extended Rule" applies to all rules and not just junk rules.

When I start up Outlook 2007, and sometimes while it's running, I get the following message:
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 on the server.
Would you like to manage your Junk E-mail Lists now?
Manage Lists... Cancel
The first time this error occurred I had only one entry in my "Blocked Senders" list from several months ago, which I have since removed. The "Safe Senders" and "Safe Recipients" lists are also empty, as are my "Blocked Top-Level Domain List" and my "Blocked Encodings List". I cannot disable Junk E-mail filtering, it is greyed out in the options. The option "Also trust e-mail from my Contacts" is selected in the Safe Senders tab of the options.
Is there any way I can prevent Outlook from attempting to add whatever lists these are to the server? Is there any other way to fix this? It's probably not a server problem since no one else is encountering this, and I'd prefer a quick client-side fix over going through IT anyways. I believe the server is running Exchange 2007, and there are no other clients in use, set up, or supported besides my BlackBerry.
