Google Apps – Office365 email co-existence

I recently migrated a large Google Apps tenant to Microsoft Office365 (10k + users). Google require a verification code to set up forwarding to a user’s .onmicrosoft.com alias. Which means it is not possible to automate the forwarding from Google Apps to Office365.

So the way we enable co-existence is as follows.

Domain Name : Contoso.com 

  1. Add an alias domain into Google Apps. Relay.contoso.com. Google state that this can take up to 24 hours. I have seen it complete in 10 hours. This will add an alias to all Google Apps users  user@relay.contoso.com
  2. Export all Office365 user’s userprincipal names to a csv.
     
  3. Enable forwarding for all users in Office365 to their smtpaddress@relay.contoso.com. This is done by using the following powershell command in Exchange Online.
    Import-Csv “C:\Users\sofarrell\Desktop\RelayAddress.csv” | Foreach-Object{Get-Mailbox $_.DisplayName | Set-Mailbox -ForwardingSMTPAddress $_.MailAddress -DeliverToMailboxAndForward $true} -verbose
  4. When the last mailbox has migrated we then remove the forwarding and edit the delivertomailboxandforward value.
    Get-Mailbox | Set-Mailbox -ForwardingSmtpAddress $null -delivertomailboxandforward $false

Sync Multiple AD Forests and Google Apps Directory into Office365

I have recently began using a product called CloudAnywhere from CloudiWay which has some really excellent features like:

  • Syncronise multiple Active Directory Forests and passwords into Office365
  • Syncronise Google Apps Directory into Office365.
I recorded a VIDEO showing some of the features of the product.

Google Docs Storage

My laptop’s hard drive is starting to make a clicking sound. I have been meaning to replace it for some time but just have not got around to it. So prior to it dying I am uploading all the pics of my little boy Jayden to Google Docs storage. Each user gets a standard 1GB storage but I purchased an additional 20GB storage for $5.00 a year!!!

I always use yousendit.com for sending files i need for work like hot fixes and patches. Mostly any email package or service will put restrictions on sending .exe files , but the free version only allows sending a maximum of 100MB. With my google docs storage I can easily share a folder and send the link to somebody and they have the required file, files.

Its really simple to use and I feel safer having my files in the cloud. I will however have to make my password stronger!!
