Export Email Addresses in Exchange 2013

For a project I had to create a CSV file with all Mailboxes, their UPN and their Email addresses. Not a big deal since you can use the following command:

Get-Mailbox | Select UserPrincipalName,EmailAddresses

Exporting to a CSV is a default feature in PowerShell using the Export-Csv command, like this:

Get-Mailbox | Select UserPrincipalName,EmailAddresses | Export-Csv C:\Temp\Addresses.csv

Purge deleted users in Office 365

When deleting users in the Microsoft Online Portal these deleted users are moved to the Recycle Bin where they will be retained for another 30 days. You can see this when selecting Deleted Users in the Portal:

In the Portal it is not possible to permanently remove users, or purge deleted user accounts. This can only be done using Remote PowerShell. Please note that the Azure Active Directory Module for Windows PowerShell need to be installed. Click here to install this PowerShell module. Continue reading Purge deleted users in Office 365

Exchange Server 2013 CU7

On Tuesday December 9, 2014 Microsoft released Exchange Server 2013 Cumulative Update 7 and the UM Language Packs for Cumulative Update 7, 105 days after the release of the previous CU6 update. This release is a little overdue because of a last minute issue that was found moments before the original release date of CU7. As long as it improves the quality of the release this shouldn’t be a problem though.

CU7 contains fixes for issues reported by customers, including the Russian Time Zone issue and fixes for issues identified in MS14-075. Updates for MS14-075 are also available for Exchange Server 2013 Service Pack 1 and Exchange Server 2013 Cumulative Update 6. Because of the Microsoft (N-1) support policy this hotfix won’t be available for CU5.

Can’t verify domain

Recently I configured a new Office 365 E3 tenant for my lab environment and one of the domains I use (and had in mind for configuring Federation) was exchangelabs.nl.

When adding a domain to a tenant Microsoft has to verify if you’re the owner of the domain being added and this is achieved by you adding a TXT record to public DNS. Microsoft checks for this TXT and thus knows you’re the one and only owner.

After adding the TXT record the verification wizard failed with the following error:

Can’t verify domain

Exchangelabs.nl was already added to a different Office 365 account exchangelabs.onmicrosoft.com.
Sign in to that account as ad admin, and remove domain <domain>. Then come back here and try adding <domain> to this account again.
If you can’t sign in to exchangelabs.onmicrosoft.com as an admin, try resetting your admin password. Continue reading Can’t verify domain
