Hi,

We installed Exchange Server 2013 SP1 a while ago and noticed two directories were created:

D:\MonitoringDiagnosticLogs\MSExchangeHMHost (Contains a file called MSExchangeHMHost20141231-1)

and

D:\TransportRoles\Logs\SyncHealth\Hub

I also noticed the second folder is addressed in Cumulative Update 5.

I have the following questions:

1. Does applying CU5 remove the second directory? If not, is it safe for me to delete this directory?

2. What about the first directory? How do I get rid of that? Is it safe for me to delete it?

3. If I cannot get rid of the two directories is it safe for me to create a new partition, move the directories to it, and mark it as D:\ so the path remains the same?

Thanks for the help!

No even after applying CU5, you will not get rid of those two directories. These problems have already been reported to Microsoft a long ago but the company has not taken any step to resolve it yet. Even after applying CU7, many users are still facing the same problem. 

D:\TransportRoles\Logs\SyncHealth\Hub must be empty, so I don't think it should create any problem.

Could you please confirm if you are facing any type of problems with those two directories?

Hi,

Based on my research, the two additional directories are created on this D:\ drive during installation of Exchange 2013 automatically:

• D:\MonitoringDiagnosticLogs\MSExchangeHMHost
• D:\TransportRoles\Logs\SyncHealth

Currently, there is no official document about this issue. Since it will not cause any issue, you can leave it there.

We will wait for the official explanation of the issue. We highly appreciate your kindly understanding and patience.
