An exchange server I manage had up to 30GB of log files. Maybe you need log files, maybe you don't. There are a number of methods in dealing with log files when you do need them. Here's an awesome web page giving you a ton of different options. I chose the option to remove log files after 30 days. Note that these are for IIS logs, not Exchange Logs. http://www.iis.net/learn/manage/provisioning-and-managing-iis/managing-iis-log-file-storage#02 And the VBS Script that I'm now running in Task … [Read more...] about Script to delete or manage IIS Logs

MS Exchange 2013 CU6 (Issue was happening as far back as CU4) One Exchange Server managing all Exchange services and responsibilities Less than 50 mailboxes Overview Basically, every few days we'd get a call in the middle of the day from customers telling us that mail was being stuck in the Outbox in Outlook and mail would be put into the drafts folder in OWA.

While upgrading to any service pack or CU of Exchange 2013 (and earlier), you can't have other CU's installed. Before you can get started with an upgrade, head into Programs and go to "View Installed Updates." Be sure and remove the CU or SP that you have installed, then start the upgrade. Otherwise, this will be your error: In this example, the CU could be any version before the version you're trying to upgrade. Keep in mind, a service pack is just a glorified CU, so you'll get … [Read more...] about Exchange Upgrade Error: Unable to install because a previous Interim Update for Exchange Server 2013 Cumulative Update 1 has been installed.
First things first. Here's where you can download everything: Office 2013 SP1 32-bit Office 2013 SP1 64-bit Exchange 2013 SP1 Project 2013 Server SP1 The Service Pack has been long awaited and long expected. I posted about the Service Pack when Microsoft blogged about it, then followed up again recently with notice that it still hadn't released yet, even though "early 2014" was running out. ZDNet was on top of the details regarding Outlook and Sharepoint Updates. Here's a list of … [Read more...] about Exchange, Sharepoint, Project, and Office 2013 SP1 Download Available
Are we getting ahead of ourselves here? Granted, I'll give it to them, it's only the beginning of February. So when Microsoft and their Exchange Team reported a Service Pack 1 Release date of "Early 2014" we may just be a little impatient. Maybe we should be giving them until the end of Q1 before pounding down their doors with torches and hay forks. While the scheduled release date may still have time, reporting the release date is just as important. It isn't too impatient of us to expect … [Read more...] about Exchange 2013 SP1 Release Date: Still Unknown

There is still no set date for the release of SP1 just yet. "Early 2014" is still the best we've heard at this point. My latest post doesn't give much of an update. I'll be sure and keep the world posted. Microsoft announced the release of Service Pack 1 (SP1) for … [Read more...] about Microsoft to Release Outlook, Sharepoint, and Exchange 2013 SP1 in Early 2014
UPDATE: After SP1, this issue is gone, and all services can be run normally. There's a good chance this issue was fixed at CU3 as I'm seeing user feedback in posts I was following claim that CU3 fixed the problem. Either way, life is better on SP1. This issue looks to be specific to Microsoft Exchange 2013 CU1. My environment is running Server 2008 R2 on a Server 2008 R2 Domain Level. At the time of this post, there is no telling if CU2 fixes the issue. Issue: Here's what you'll see in … [Read more...] about Exchange 2013 RPC Client Access Service keeps restarting
