Exchange 2013 OWA Mailbox policy issue cause of OWA error?

Reading Time: 4 minutesWithin Exchange 2013 you can have OWA (Outlook Web App) Mailbox policies, in which an Exchange Admin can determine which features within OWA are available to users. By default, there's a default policy with all options enabled, but you can have more policies and configure them at will and assign them to Mailbox-enabled users according to the organization's needs. In this case we wanted to completely disable the Text Messaging option, as it offers no additional functionality for this organization. Disabling it

My portable lab hardware

Reading Time: 2 minutesRecently somebody asked via Twitter my what the make and model is of my laptop, used for Exchange testing environments. Well, 140 characters is not a lot of space so I decided to blog about it. Our company uses Dell laptops as a laptop standard, but other vendors might have comparable configurations. The main model type is a Precision M4700, but for lab purposes the configuration has been customized: CPU: Intel Core i7-3820QM @ 2,70GHz Memory: 32GB (4x8GB) 1600MHz DDR3

Script converting Mail-User to Mailbox-User

Reading Time: 2 minutesNot all organizations need to have every user to be mailbox-enabled, sometimes a mail-user (also referred to as mail-enabled user) with a forwarding SMTP address to an external mailbox is enough. However, it is surely possible that the requirements over time change and the mail-enabled user does need to be mailbox-enabled, making use of the calendar or perhaps even more efficient use of Lync integration. However, converting a mail-user isn’t just changing the RecipientType of the account. First the users

The mysterious Exchange App, the new ActiveSync?

Reading Time: 2 minutesRecently the backend of my Office 365 P1 account was upgraded to the Wave 15 series of products, which obviously includes Exchange 2013.
