Out Of Office not working in outlook 2003 after migration from EX2003 to 2010

Hello all,

I have a problem with some outlook 2003 clients, when you open Out Of Office the following message appears.

"The Out Of Office Assistant could not be displayed. Your server could not be located."

The client is connected.

It has not occurred on all 2003 clients however it is starting to happen to more as time passes since the migration. I have a laptop on my desk which I have been using to play about with a mailbox used just to send Out Of Office replies to queries. Out Of Office worked fine on it when I left the office on Wednesday, I just tried to use it and now it is getting the same error as a few users have been reporting since the migration.

I can't find anything useful on the web!

Thanks for reading.
S.

Hi,

Check the EWS virtual directory authentication and set it to anonymous and integrated.

Restart the IIS.

Also disbale any proxy settings on the desktop.

Hope this helps,

I have checked the settings in your first post and they are correct. Reading your second post made me think, can you tell me how to check the internal/external URLs for the EWS site using this newfangled IIS?

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

I think I am getting somewhere, I ran Get-WebServicesVirtualDirectory | Format-List and the URL for the EWS VD is not what I want it to be. I don't know how to change it though...

Update:

I successfully changed the internal URL for EWS and that has not resolved the issue. However I have found something very interesting.

Out Of Office works fine with cached exchange mode off. If I turn Cached mode off delete the users OST and turn it on again Out Of Office continues to work until the users logs off and on again at which time Out Of Office stops working.

Most odd.

Hi Sam,

- Under Outlook 2003> Tools> Options> Secuirty> Check Encrypt contents and attachments for outgoing messages. Then check Out Of Office.

Does the Exchange 2010 has been updated with Update Rollup 2 for Exchange 2010? If not then update it and check.

Still issue not resolved then Remove and recreate the EWS virtual directory:
- Get-WebServicesVirtualDirectory >>Copy the output to notepad

- Then you can remove the Virtual Directories but change the XXXXXXX to the information you got earlier
Remove-WebServicesVirtualDirectory -Identity "EWS (XXXXXXX)" -Confirm:$false

- Information you have to provide is in BIG LETTERS or XXXXXXX
New-OWAVirtualDirectory -WebsiteName "XXXXXXX" -OwaVersion "Exchange2003or2000"
-VirtualDirectoryType "PublicFolders" -ExternalAuthenticationMethods Fba

Hope this helps,
Shree

I am an idiot. I forgot that the CAS server hadn't been updated with rollup2 all the other servers were but not that one.

am trying this to resolve our OoO issues, but please don't do as I have and install during working hours - what none of the documentation tells you is that it shuts down all the processes and stops your mail server.  Red faced explanation to boss ensues...
