As some might know (although I and others have to repeat this regularly…), if you enable directory synchronization from your on-premises Active Directory (AD) and you migrate all you Exchange mailboxes to Exchange Online you still require an Exchange server to manage mail(box) objects. It is the only supported solution, even though some use third … Continue reading "Can I place my Exchange hybrid management server in Azure and use Azure Domain Services?"
Microsoft states that Exchange 2010 and 2013 are secure out of the box. With this they mean that every traffic coming in and out of Exchange is one way or another encrypted with security protocols. Whether this is web traffic or specific for SMTP. Even IMAP and POP are enabled with mandatory encryption (although the … Continue reading "Checking security protocols and ciphers on your Exchange servers"
Sometimes you're not at work and you suspect there is something wrong with your Exchange 2013 servers and you can't access your environment remotely for whatever reason. Well, in some cases you can check this with just a browser. For each Exchange protocol, there is an URL you can use to check the health. The format … Continue reading "Using your browser to check Exchange 2013 protocol health"
This week I had a session at a customer to customize the default RBAC roles, for instance removing the mobile device remote wipe feature from Recipient Management. Customizing RBAC roles is in most cases not something that is a frequent task, so it can take a while to familiarize and re-familiarize with the concept and … Continue reading "Tool Tip: RBAC Manager R2 for Exchange"

During a discussion about fighting spam, a coworker mentioned an interesting Gmail feature.

Some use a different email address for each service they sign up for, a practice which is understandable with some services that (sometimes illegally) … Continue reading "Mail address sieve and Exchange"
So, a while back I discussed an on-premises Exchange design for a customer. When discussing database distribution in an Exchange 2013 Database Availability Group (DAG), the topic of mailbox quota’s came along. They insisted on having different Database (DB) level quota’s and move mailboxes to other databases when the user requires more storage space. It’s … Continue reading "Managing Mailbox quota’s: databases with different settings?"
Most Exchange admins probably know (or should know ) the permission model since Exchange 2010 is Role Based Access Control, RBAC for short. With it, you can regulate quite granularly what admins and end-user are able to do, without the hassles of Access Control Lists (ACLs). However, it recently became clear that it might be … Continue reading "Exchange RBAC might be more granular than you think"
I think I might start a new tradition: every time a major/important OS or update is released, I try find out how to block it from Exchange . Now, I know the Mail app has been around for some time now. If you recollect, I did some research on how Exchange ActiveSync (EAS) within the … Continue reading "Blocking the Windows 8 Mail app in Exchange 2010 & 2013"
Now that iOS 7 available, it might be interesting to know how to block this version. In the past there were some issues with the Exchange ActiveSync implementation in specific iOS DeviceOS versions (read this and this).
