Who knew that users would actually get upset if they don’t get their Missed Call emails? Who knew that they would also get upset if they received hundreds of notifications in their email that they missed all of those calls while out on maternity/paternity leave? Who knew that users would get upset no matter what?
Oh wait, all of us admins knew.
Not much has changed in the last several years regarding how the Missed Call Notification works. Jens Trier Rasmussen covers the process very nicely, and it is still pretty accurate, today.
Recently, I have had a couple of users complain that they are not getting their notification emails. The answer, in these cases, has been simple. Would you guess it is because they have too many folders in Outlook? Yes, it is the same issue as with Conversation History not being saved after it has worked for a long time. Exchange Web Services has an issue when there are over 1,000 folders in the mailbox. Once the mailbox is cleaned up, the Missed Call Notification starts working again.
Of course, the best solution might just be to turn it off for everyone by using a Client Policy: Set-CsClientPolicy “PolicyName” -EnableCallLogAutoArchiving $False
If users want to disable the notifications, they can do it in the Lync/Skype for Business client application: In Lync/Skype for Business, click the Gear in the upper tight, then click on Tools, Options, then click on the Personal tab and disable the checkbox for Save call logs in my email Conversation History folder.
