All things Exchange
The Exchange 2010 OAB needs some love and attention after it has been created with the default settings. While things may not be broken, they are less than ideal.
The Exchange OAB was last really overhauled with Exchange 2003 SP2 and Outlook 2003 SP2. This was the move to the fourth generation of OAB and was done for many good reasons. They included:
Exchange 2016 CU3 has been released to the Microsoft download centre! Exchange 2016 has a different servicing strategy than Exchange 2007/2010 and utilises Cumulative Updates (CUs) rather than the Rollup Updates (RU/UR) which were used previously. CUs are a complete installation of Exchange 2016 and can be used to install a fresh server or to update a previously installed one. Exchange 2013 ha… Read the rest “Exchange 2016 CU3 Released”

For those who worked with NT and Novell Netware many, many moons ago they became familiar with a handy function– who am I. Windows folks may also recall it when working with the Client and Gateway Services for Netware, and whoami.exe was also added to the NT Resource Kit. Remember the days of all the fun res kit tools? *
The whoami command does exactly what you would expect, it tells you who you … Read the rest “Remote PowerShell – PSSession WhoAmI”
The concept of arbitration mailboxes is not really new, they were first introduced in Exchange 2010. Arbitration mailboxes are used for several special tasks within Exchange and for the most part will tick away quite happily with minimal administrator intervention. System mailboxes have existed for much longer in Exchange, and again perform special tasks which are required by Exchange.
A lot of a… Read the rest “When To Move Arbitration Mailboxes”
Patch Tuesday this week heralded the arrival of Rollup Update Rollup 15 (RU15) for Exchange Server 2010 Service Pack 3. RU15 is the latest rollup of customer fixes available for Exchange Server 2010. The release contains security fixes to address the issues in Microsoft Security Bulletin MS16-108, in addition to the previous fixes in RU14 and older.

After updating Windows 10 you may be unable to connect to a remote PowerShell session. This is an issue for versions of Exchange 2010 onwards as we use remote PowerShell for administration. The same applies for Exchange Online in Office 365. Note that directly loading the Exchange PSSnapin is not supported apart from a limited number of documented scenarios, for example this is one of them. For… Read the rest “Unable Connect Exchange Remote PowerShell Using Windows 10 Anniversary Update”
This is a link throw-down for the items discussed during a recent Office 365 workshop that I delivered to customers in a rather tropical Winnipeg last week. It has to be said that the +30 Winnipeg is much better than the –30 Winnipeg!
I’m posting the links here since they will be available to all of the attendees, and thought that others may also find them useful/interesting.
In recent builds, Exchange has been updated to support the newer SHA2 certificates. Exchange 2010 SP3 RU13 and Exchange 2013 CU 12 updated the SMIME control’s certificate to SHA2.
Additionally, Exchange 2013 CU13 and Exchange 2016 CU2 added support for generating the self signed certificates as SHA2 certs.
The below is for reference to save having to spin up labs in the future to review differences i… Read the rest “Exchange Self Signed SHA2 Certificates”
When configuring an Exchange Online hybrid deployment, there are many things to consider. Asides from the various networking, certificate and client discussions there is also a requirement to ensure that Autodiscover is functioning correctly. In addition to having Autodiscover correctly published to the Internet an additional wrinkle commonly pops up, which takes people down the wrong garden pat… Read the rest “Office 365 Exchange Hybrid Deployments Busting The Autodiscover Myth”
