Hi,

We have exchange 2013 CU5 setup where we enabled mail tip settings as follows

MailTipsAllTipsEnabled                : True
MailTipsExternalRecipientsTipsEnabled : True
MailTipsGroupMetricsEnabled           : True
MailTipsLargeAudienceThreshold        : 25
MailTipsMailboxSourcedTipsEnabled     : True

But still the alert while doing a reply all to BCC is still not working

What could be the issue

Hi

First we need to ensure that owa is able to access the ews virtual directory without any issues. Also ensure that outlook is able to fetch the Autodiscover information.

First identify the MailTip issue is happening for just one user or multiple users. Also if it is will all users pick one user and start troubleshooting.
Check if the mail tip is not functioning in owa and outlook or any one of them.
Ensure that outlook is able to get the correct Autodiscover information.


Tools for troubleshooting MailTips

Exchange and Outlook provide tools for troubleshooting mail tip issues. Below is a listing of the tools that we can use to identify and resolve mail tip issues;

1.         Outlook 2010/2013 Diagnostic Logging (MailTips.log)

2.         Internet Information Server Logs

3.         Diagnostic Logging (Event Viewer)

4.         Performance Monitor Counters



 Steps to enable Outlook logging

File Options Advanced Enable troubleshooting logging

Restart outlook, try to retrieve MailTips and you will get a below kind of log

You need to ensure that there is no error after GetServiceConfiguration for mailtips which is a successful transaction of MailTip.

Below is an example of successful result of a query of mailtips from outlook which shows in the outlook log.

<ex15m:ConfigurationName>MailTips</ex15:ConfigurationName>

</ex15m:RequestedConfiguration>

</ex15m:GetServiceConfiguration>

</q:Body>



<GetMailTipsResponse ResponseClass=Success xmlns=http://schemas.microsoft.com/exchange/services/2006/messages>

<ResponseCode>NoError</ResponseCode>

<ResponseMessages>

<MailTipsResponseMessageType ResponseClass=Success>

<ResponseCode>NoError</ResponseCode>



Similarly we can enable IIS server logging in the CAS server and look of there are any errors after get-service configuration for MailTips so that we will be able to identify the issue.

Also we can increase the following Perfmon counters for MailTips and see the results if we get any relevant information.

Hi Manju, 

Thank you for your question. 

Did you try it in OWA if it is not working? 

By my understanding, Reply-All on BCC is only available on OWA, it will not work in outlook, we could refer to the following link:

In addition above suggest, we could reset MailTip to check if the issue persist. 

If there are any questions regarding this issue, please be free to let me know. 

Best Regard, 

Jim
