Outlook Anywhere no longer working after dissabling ssl 2.0
Posted on 2011-03-16
We are using Outlook 2007 and exchange 2003, with outlook anywhere up untill tonight. It was suggested that we dissable ssl 2.0 to make our exchange server more secure, I went in and made the following registry changes
(1.Click Start, click Run, type regedt32 or type regedit, and then click OK.
2. In Registry Editor, locate the following registry key: HKey_Local_Machine \ System \ CurrentControlSet \ Control \ SecurityProviders \ SCHANNEL \ Protocols \ SSL 2.0 \ Server
3. On the Edit menu, click Add Value.
4. In the Data Type list, click DWORD.
5. In the Value Name box, type Enabled, and then click OK. Note If this value is present, double-click the value to edit its current value.
6. Type 00000000 in Binary Editor to set the value of the new key equal to “0¿.)
and now we are having trouble sending and recieveing when using laptops off site. (they work fine on our network) also I don't know if this is related or not but there is a signifcant delay in sending emails out.
After noticing these problems, I went back and undid the registry edits but the problems still persist.
Any help would be greatly appreciated.

disabled ssl 2.0, left ssl 3.0 enabled. we reboted the exchange box after the change was made and after the change was reversed.
here is quote from wiki:
SSL 1.0, 2.0 and 3.0The SSL protocol was originally developed by Netscape. Version 1.0 was never publicly released; version 2.0 was released in February 1995 but "contained a number of security flaws which ultimately led to the design of SSL version 3.0" (Rescorla 2001). SSL version 3.0 was released in 1996.

You may want to re-clarify for all here. Your original Post says: " We are using Outlook 2007 and exchange 2003" There is a huge difference between Exchange 2003 and Exchange 2007. And yes, there is a huge difference between disabling SSL and preventing users from connecting using an older revision of the protocol.
I appologize to all, It is in fact Exchange 2007. I'm not trying to dissable ssl entirely. I'm only trying to disable SSL 2.0 as it is know for having security issues.
I should add a few things. OWA has been working fine both ways, it only seems to affect Using Outlook from outside of our network (using outlook anywhere). When I try to do a send/receive I get a error (0x8004011d)
I mentioned a delay in outgoing e-mail, it is only affecting some domains, I'm pretty sure this issue is not related to the ssl issue.
sorry for the errors, I was up pretty late last night scratching my head.

Is outlook 2003 fully patched - SP3+ all updates? Can you try to connect with Outlook 2007 - does it work?
What errors are you getting? use the ExRCA tool. Web version here: https://www.testexchangeconnectivity.com/
well, it passed. I went and expanded all and found this in the auto discover section.
Attempting each method of contacting the Autodiscover service.
The Autodiscover service was tested successfully.

Attempting to resolve the host name mycompany.com in DNS.
The host name resolved successfully.
Additional Details

The specified port is either blocked, not listening, or not producing the expected response.
Tell me more about this issue and how to resolve it

Has the server been 'bounced' since the offending reg key was removed? Try restarting all the Exchange and IIS services - or quick and dirty => reboot the Exchange servers.
If that doesn't work, you may need to play around with the Outlook Anywhare config on the server. Make sure it's setup correctly, or reset it up again.

On the send/receive does it show as downloading the address book when you get the 0x8004010D error or is it just downloading/synching mail?
I've tried restarting the server after the update, it did not resolve the issue.
When I get the 0x8004010D error, it is just send recieve

Can you screenshot that error please.
How big is your OST file? If you have upgraded from an earlier version of outlook then your OST may be limited to 2Gb

Tried turing off cached exchange, getting the same error. I really don't think that this is a client side issue as the only change that has been made was to the Server. I do appreciate the suggestions.

8004010D = MAPI_E_NOT_ENOUGH_DISK = SPACE ISSUE
This is the error you reported earlier whereas in the screenshot you have:
8004011D
Which is MAPI_E_FAILONEPROVIDER, which means it can't connect to Exchange, so forget about what I am saying about OSTs and sizes.
When you said in your post 35149171 "well, it passed..." did you mean to say "well, it failed"?
go to www.canyouseeme.org and see if it says port 443 is open to your address...

Have a look in the IIS logs and see what it is saying for your test connection. Maybe have a look in the HTTPErr#.log first to see if that is recording any errors for you. The HttpErr.log files can be found under C:\windows\system32\logfil
IIS logs should be under C:\Windows\system32\logfil
