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 ...

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 ...

Exchange 2010 has a massively improved admin permission model. It’s called Role Based Access Control and with it you can use predefined roles or make very customized roles if needed. I won’t go into details how it works, for the purpose of this issue you only need to know that the RBAC roles are assigned via RBAC Role Groups. These are actual ...

Since Exchange 2010 Service Pack 1 a new feature was added for Outlook 2007 and 2010 users, namely Automapping. When a mailbox user has Full Access on another mailbox, it will be automatically mapped in Outlook. No need for the user to go trough menus to find the additional mailbox screen. It’s a small addition but I know that users and your ...

Recently I was asked to check whether members of a distribution group were receiving mail sent to the group. In this case the group was a member of another distribution group.  First thing is to check if all nested groups are mail-enabled distribution groups. If this is not the case, Exchange will deliver to all recipients except those of ...

On a project I am currently working on, the management of mail recipients was handed over from the build/migrate team, to the administrators after the mail was migrated from the old mail system to Exchange 2010 We had to restrict the administrators temporarily from other settings, like server and organization settings, even some small restriction ...

During the first stages of delivering services of our newly built infrastructure to end-users, we came across an annoying issue. Exchange was the first to be accessed, but specifically through Outlook Web App (OWA). As the users where migrated from eDIR and GroupWise, they would get credentials from us. As a security measure we wanted to make a ...

If you find yourself unable to change the database path of an Exchange 2010 database, check whether it is part of a DAG. See the screenshot for the missing option: If so, you cannot move it. The solution is to remove all copies except the active. Now you can move the DB and Transaction log paths. Do note that you will have downtime! Changing ...

Now and then I get request to implement a default language for Outlook Web Access or App. This meant that users already had their language and regional settings set for OWA. Exchange only asks this the first time the user logs into OWA, this is because the language code is set to 0. It’s just a little service for your users for when you are ...

Somebody asked me today, whether it is a good idea to set the postmaster address in Exchange. Well, short answer: yes! It's is even mandatory according to RFC 5321 section 4.5.1. For Exchange 2010 you will have to use the Set-TransportConfig cmdlet: Set-TransportConfig -ExternalPostmasterAddress <ExternalPostmasterSMTPAddress> For ...
