Hi Exchange experts,

Exchange 2013 server, Lyn server is Skype for Business On-prem.

One of our users has the issue on the SFB conversation history saving.

Sometime it works, but sometimes there is red "!" shows up on SFB. When she close the conversation, it dosn't show up in Outlook Conversation History folder automatically.

Error message as below:

The Exchange server won't let us connect. We're working on fixing the connection. Your history, voice mail and Outlook features might be unavailable or out-of date until things are fixed.

The configuration information shows up "EWS unavailable, retrying ", "MAPI Status OK".

I know this issue related to both Lync Server and Exchange Server.

Any tips related to Exchange Server would be great.

 

Thanks and Best Regards,

Mavis

Please check that you didnt run out of your mailbox.

Check if other users can save conversation history on your computer.

Hi,

Since its working fine for the others,i guess the error is only on his/hers account. Please try to disable the issued Lync account and then enable it again to test the issue again.

If this doesnt work, check if the EWS URL is correct on client side with the following steps.

Outlook side:

1. Hold ctrl and right-click on outlook icon, then click Test E-mail AutoConfiguration.
2. Uncheck the box Use Guessmart and Secure Guessmart Authentication, then click test.
3. In the result, check make sure the URL of EWS is correct.

SFB side:

1. Right-click on SFB icon, choose configuration information.
2. Check the EWS internal/external URL.

Best Regards.
