Don’t want your #Office365 to be upgraded to the new 2013 wave yet? Then you only have 1 chance to postpone it and that is during the first 3 weeks of your 4 week notice of upgrades.
At the bottom of the email you get about your 4 week notice, you will get P.S. saying you can postpone it.
To postpone it you need to log into your Office 365 portal site at http://portal.microsoftonline.com with Global Administrator rights where you will be presented with the following at the top of the page.
Click on Service update options to start the postponement.
You are now presented with a bit of information telling you that you don’t have to worry about anything when the upgrade happens and that there will be no service interruption.
The second part allows you to postpone the upgrade process. This might be for 30, 60 or 90 days depending on your tenancy.
Click on Postpone upgrade if you want to and it will tell you that you can only postpone it once.
