Exchange Subscriber Access not recognizing any mailbox extension RRS feed

  • Question

  • Hello, 

    Our Exchange 2010 subscriber access is not recognizing any mailbox extension, when called from a phone or Lync 2010 client, users will enter their extension and they get a message sayoing "XXXXX is not a valid mailbox extension". This is happening to every user. Even when calling from a Lync 2010 client, usually hitting the Change Greetings option from the Lync client would call SA and the user would immediately be logged in to their voicemail without entering their extension. But now when hitting change greeting option, SA asks the user to enter their extension and when they do they get the message that the extension is not valid.

    SA was working fine previously. All of the sudden it started acting like this a week or two. I have checked Event Viewer and don't see any errors from mxExchange Unified Messaging.

    Please any help is appreciated! Thanks.

  • Hi Eightbitsshort,

    I'll move this thread to Lync integration forum, as they should have more professional knowledge on it and you may get effective solution timely. Thanks for your understanding,

  • Hi Leon, 

    Thanks for your reply. I did find that link before I posted my problem here. Per the article, I did check the msExchUMEnabledFlags attribute for all my users and it shows the correct value. So it doesn't seem that solution applies to my case.
