Now that Microsoft has purchased the Sunrise Calendar app, it's probably a good idea to take a closer look to that app and see what we are or will be dealing with before everyone panics (again). The Acompli Outlook app for iOS and Android (from now on referenced as just the Outlook app) has received … Continue reading "A quick look at the Sunrise Calendar app"

Some things to do after leaving Windows Server 2003 (from an Exchange perspective)
Today the Exchange Team blog posted an article about upgrading the Domain Functional (DFL) level of your Active Directory environment away from Windows Server 2003 and the fact that raising the level might have some impact on your Exchange servers (and other applications). It is possible that they might not be able to authenticate. If you … Continue reading "Some things to do after leaving Windows Server 2003 (from an Exchange perspective)"
No, Windows Phone ActiveSync is not on par with OWA for Devices
Recently I came across this Twitter exchange: @WayneHRiddle You don't need it for WP. Native app handles all of that functionality. — Ben Rudolph (@BenThePCGuy) January 17, 2015 I've heard this argument before, that the Exchange ActiveSync (EAS) implementation in Windows Phone doesn't require an OWA for Devices app (or MOWA as is the official acronym) … Continue reading "No, Windows Phone ActiveSync is not on par with OWA for Devices"

Mail address sieve and Exchange
During a discussion about fighting spam, a coworker mentioned an interesting Gmail feature. As that service doesn't provide aliasses, you can't have a specific mail address alias for your internet services. 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"
Exchange 2013 CU4 (SP1) and Outlook for Mac 2011 Error 19721
Recently I upgraded our hosted exchange 2013 CU1 servers to CU4 (aka SP1). I didn’t do an in-place upgrade but I chose rather to build an Exchange 2013 CU4 environment and then migrate all mailboxes. The migration process went relative well, except for one peculiar problem: Mac users with Outlook for Mac:2011 couldn’t send e-mails … Continue reading "Exchange 2013 CU4 (SP1) and Outlook for Mac 2011 Error 19721"
Optimizing the Outlook AutoDiscover process by skipping the root domain query
Updated 8/15/2014: see the bottom of this article for additional information on changed AutoDiscover behavior of Outlook 2013. Consider the following scenario: An Active Directory (AD) domain named equal to the SMTP Suffx, so the mailaddress dmstork@contoso.com in the contoso.com AD domain. No on-premises Exchange, this means that there is no Service Connection Point (SCP) in … Continue reading "Optimizing the Outlook AutoDiscover process by skipping the root domain query"
Managing Mailbox quota’s: databases with different settings?
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?"
Exchange mail flow not working? Check your (Cisco) firewall!
I’ve come across this issue several times: External mail (or mail between Exchange servers) cannot be delivered, however when you check with telnet the Exchange server(s) are responding. When you check via telnet on the external IP you get something similar: In this case it was a Cisco ASA firewall that had (E)SMTP filtering feature … Continue reading "Exchange mail flow not working?
