Cheat Sheet: Setting Exchange Mailbox User Permissions via PowerShell

One of the things I get asked about quite a lot, is how you can set specific permissions in Exchange Server and Exchange Online. Most cases the Management Console (in 2010) or the Exchange Admin Center (EAC, Exchange 2013 & 2016 and Online) provide most basic permissions like Full Access, Send As and Send On Behalf. However, sometimes an admin has to set Send on Behalf permissions on a Shared Mailbox or disable AutoMapping, those options are not available via

Azure Active Directory Synchronization: Filtering, Part 2

This post is the fourth in a series about Azure Active Directory Synchronization and will cover Filtering. Originally I've planned to make this one post, but in my opinion it became to large and complex thus again a part 2. Other posts have covered and will cover: Introduction, Part 1 Introduction, Part 2 Filtering, Part 1 Object Matching Alternate Logon ID In the previous post I discussed why and how to filter: Domain, Organizational Unit or Attribute based filtering. When to

Azure Active Directory Synchronization: An Introduction, Part 2

This post is the second in a series about Azure Active Directory Synchronization, covering part 2 of an introduction. Previous and follow up posts have covered and will cover: Introduction, Part 1 Filtering, Part 1 Filtering, Part 2 Object Matching Alternate Logon ID As most organizations will not require FIM, I will focus my attention mostly on AADSync. Although DirSync is (unless features from AADSync are required) the first choice, it's deprecated, but more importantly: most concepts are still unchanged.

A quick look at the Sunrise Calendar app

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 praise regarding it's functionality and usability, but also a lot of criticism on security and compliancy. A major issue is the temporary caching of data and

Issues with Unified Contact Store in combination with Lync on-premises and Exchange Online

I've encountered an issue that popped up while I was testing a move from Exchange On-premises to Exchange Online (EXO) while Lync Server 2013 remained on-premises due to Enterprise Voice. Outlook Web Access (OWA) from Exchange Online can be integrated with on-premises Lync, this way OWA users can see presence and have limited IM functionality just like what's possible if both products are on-premises. For this to work you'll need Lync Edge servers because OWA EXO will act as an

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) opt-in bulk mailings or more nefarious mailings. Whenever a specific alias receives unwanted mails, you can see where it came from and take direct action

Fixing Office 365 DirSync account matching issues

Recently I had to fix some issues with DirSync. For some reason (there were some cloud users created before DirSync was enabled) there were duplicate users, because DirSync failed to match the already present cloud user and the corresponding AD (Active Directory) user. There were also accounts that failed to sync and thus failed to sync all attributes properly. If there is already a cloud account and there is need for a synced account, you can create an AD account
