• Lync client 2010
• Outlook 2010
• Exchange 2010

I have one customer who says that Lync conversations have always appeared in her Conversation History at least a week after the conversation happened. I verified that the last 9 days of Lync conversations are not in her mailbox (same in OWA and Outlook), but it will take a few days of observation to confirm that old conversations are eventually saved.

She uses two separate computers, and the same thing happens on both.

I confirmed that she does not have any filters applied to her Conversation History folder in Outlook.

While I was looking at her computer, one Lync conversation said "This conversation is saved...", but it wasn't in Outlook or OWA. I searched her entire mailbox, and it wasn't there. So where did it go?

Ctrl-S does the same thing. Lync says it saved the conversation, but it's not in the Conversation History folder in Outlook or OWA.

Does anyone have any ideas what would cause

Hi,

From your description above, the issue only happen for one user.

If it is the case, Lync Client uses MAPI connection to save the chat session in the history folder and show you the presence of the users within Outlook. So please check if MAPI connection is ok by holding CTRL and right click on the Lync icon in the system tray and select "Configuration Information"

Also, on Lync 2010 client--Options--Personal--Personal information manager, make sure the option "Microsoft Exchange or Microsoft Outlook" choose.

HI,

please confirm that users smtp and sip address is the same.If not this kind of issue will occure,but you can disable it in cs-clientpolicy and set DisableEmailComparisonCheck to true.

Set-csclientpolicy -DisableEmailComparisonCheck $true

If this is not the case,please check EWS status by right click lync icon in notifycation area and choose configuration information.

Golden rule here is to have UPN,SMTP and sip the same.
