First of all
you'll need to check if your Office 365 Organization (tenant) is upgraded
properly. You can do this by connecting to the MSOL via the MSOL powershell
module.
Check your tenant status
2.
Open Windows PowerShell (I prefer to do it from the
runtime in a normal powershell session but you can also use the Windows Azure Active
Directory Module for Windows Powershell directly)
3. Execute the
following commands:
Import-Module MSOnline #for powershell v3 and v4 this step is not needed
Import-Module MSOnline #for powershell v3 and v4 this step is not needed
$cred =
Get-Credential <global admin account Office 365>
Connect-MsolService -Credential $cred
(Get-MsolCompanyInformation).CompanyTags
Connect-MsolService -Credential $cred
(Get-MsolCompanyInformation).CompanyTags
You now should
see that your tenant is version 15:
Check your Exchange Online Organization status
The next step is to verify if Exchange online is upgraded to wave
15. For this you need to create a pssession to Exchange Online.
1. From within
the earlier created powershell session connect to Exchange online with the
following commands:
$session = New-PSSession -ConfigurationName
Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $cred
-Authentication Basic -AllowRedirection
Import-PSSession $session
2. Next get the
organisation version with the following cmdlet:
Get-OrganizationConfig | fl Name,
Admindisplayversion, IsUpgradingOrganization
3. You now
should see the following information if your tenant is upgraded:
Note: If the AdminDisplayName says 15.0.* then your organization is
upgraded.
Verifying mailbox version
The last step is verifying that all the mailboxes are upgraded properly
to wave 15.
1. Execute the
following oneliner in the powershell session you created in the previous step:
Get-Mailbox -ResultSize unlimited | where
{$_.MailboxRelease -ne "E15"}
Note: This command
retrieves all mailboxes that do not have the E15 mailbox version.
2. If you do
not get anything back you're all done :)
