Hello, we've been experiencing some excitement over here due to excessive logging in Exchange 2016. We have a single Exchange 2016 server (CU20) and we've been doing mailbox moves from an old Exchange 2010 server that is going away as soon as we get finished.
Anyway, we have close to 1000 mailboxes and have moved almost 850 at this point. Exchange 2016 has two mailbox databases each about 500Gb in size at this point. The database logs are not a part of this post, they are under control using backups and a standard truncation schedule.
The logs I am referring to reside in the following directories. In a 24 hour period, I've seen these take as much as 15Gb.
C:\inetpub\logs\LogFiles\W3svc1
C:\inetpub\logs\LogFiles\W3svc2
C:\Program Files\Microsoft\Exchange Server\V15\Logging\NotificationBroker\Client
C:\Program Files\Microsoft\Exchange Server\V15\Logging\Ews
C:\Program Files\Microsoft\Exchange Server\V15\Logging\HttpProxy\Ews
C:\Program Files\Microsoft\Exchange Server\V15\Logging\HttpProxy\Mapi
C:\Program Files\Microsoft\Exchange Server\V15\Logging\MapiHttp\Mailbox
C:\Program Files\Microsoft\Exchange Server\V15\Logging\HttpProxy\Owa
C:\Program Files\Microsoft\Exchange Server\V15\Logging\HttpProxy\Eas
C:\Program Files\Microsoft\Exchange Server\V15\Bin\Search\Ceres\Diagnostics\Logs
Is there something that can be done to prevent these logs files from consuming so much space or is this just by design? I've had to create a daily schedule task to delete anything in all of these directories older than 24 hours just to prevent an unplanned outage. The OS volume is allocated 100Gb and was down to 8Gb this morning free space. Yikes. Back to 21Gb free this morning after deleting log files.
