Does your Office 365 DNS records check fail?

Recently I was working on building an hybrid Exchange 2013 environment. During the setup for specific mail domains, Office 365 didn’t seem to see the DNS records required. In this case it was the SPF record, that would not be accepted. However the record was made as specified as requested, TTL was an hour and after several hours it still didn’t pass the check. Other records made at the same time, were checked okay. Unfortunately that delayed other required changes…

I will be presenting at the NGN Exchange evening event on 25th November

On the 25th of November the Dutch usergroup NGN (Netwerk Gebruikersgroep Nederland) will organize an Exchange themed evening event and I’m one of the speakers. I’m extra excited as it will be held at the OGD ICT Diensten head office in Delft, my employer! My session will be about Exchange and mobile devices, focused on ActiveSync but also on Outlook Web App and the OWA App for iPad/iPhone. A very interesting and currently relevant topic, if I say so myself

The mysterious Exchange App, the new ActiveSync?

Recently the backend of my Office 365 P1 account was upgraded to the Wave 15 series of products, which obviously includes Exchange 2013. But going through the settings of the Exchange Admin Center, I noticed something that made me curious. When you go to the Exchange Admin Center, click to Recipients>Mailboxes and select a user, you can see in the Mobile Devices section the option to disable the Exchange App below the option to disable Exchange ActiveSync. I’ve highlighted it

Managing mailbox storage use in Exchange 2010, Part 2

In the previous part (yes, I know. It’s from May… I’m very ashamed) I discussed using PSTs or the built-in Personal Archive (also referred to as Online Archive). In this post we will discuss third party archiving solutions and Exchange Online Archiving which in this case is service part of Office 365, although you can mix it with an on premises solution. (see the possible confusion) Third Party Archiving As it seems, organizations had long ago issues with overflowing Exchange

See the difference Office 365 can make

I’ve blogged about my own experience regarding Office 365 in the posts Migrating to Office 365 Part 1: Business Case and Migrating to Office 365 Part 2: Exchange Cutover migration tips. I did show a picture of my “server room”, but now I actually have dismantled the physical servers and the difference is best shown in the following pic: To be fair, only the three computers on the floor are active. On the table two switches, a KVM and a

Exchange 2010 calendar publishing URLs are not updated after migrating to Office 365

With Exchange 2010 Service Pack 1 it became possible to share your calendar with anyone outside of you organization, depending on the Sharing Policy implemented by your Exchange Administrator. Users can then share their calendar via an obfuscated or an relatively public URL without the need for authentication (and SSL for that matter). For more information on how to prepare your environment if you want to enable it, see this blog post. However, if an user has this enabled on

So in Migrating to Office 365 Part 1: Business Case I’ve discussed reasons for migrating, budget and the selected solution. Now I’m going to discuss the technical migration of on-premises Exchange 2010 SP1 mailboxes to Office 365 Exchange Online. Cutover migration As I have chosen the P subscription, my options are somewhat limited as you can see in this matrix. So, cutover migration it is!

Send As permission on Office 365 not with Add-ADPermission

With an On-Premises Exchange 2010 environment an administrator hands out Send-As permission with the Add-ADPermission cmdlet. But I found out that this doesn’t work in Office 365. In this case a P plan (no Dirsync, Federation or such), you can see the result in the screenshot: Funny thing is that if you try Add-MailboxPermission to add Send-As permission, the error message redirect you to Add-ADPermission. For handing out Send-As permissions (and other rights) in Office 365, you’ll have to use

Lync 2010 on Android! Screenshots!

I’ve installed Lync 2010 for Android on my HTC Desire, which is upgraded to Android 2.3 via this update. Configured to use my Office 365 P1 subscription and made some screenshots! Configuration is easy, just enter the correct credentials and voila! You will have to prepare on the Lync 2010 Server end, but this is already done for Office 365. You can change your Status, the What’s happing ballon, see Options and the menu button shows the Sign Out button.
