Managing your Microsoft Account-owned Azure Subscription with your Organizational Account (AAD)

There might be a situation where

  • you have an existing Azure Subscription associated with your Microsoft Account,
  • you want to manage the subscription using your Organizational Account(s) (Azure AD),
  • you don’t want to or cannot transfer the ownership of the subscription to the Organizational Account – e.g. it is a sponsored subscription where the sponsorship is related to a specific Microsoft Account (Microsoft Partner Network, MSDN Subscription, MVP Sponsorship, etc.).

The trick here is to change the directory of the subscription to your Azure AD directory. Changing the subscription directory is a service-level operation. It doesn’t affect your subscription billing ownership, and the Account Admin still remains the original Microsoft Account.

There are only a few simple steps to follow:

1. Invite the Microsoft Account to your Azure AD as a guest user

To be able to change the directory, your Microsoft Account owning the subscription must exist in the target Azure AD. To associate the MSA with the AAD:

  • Login to Azure Portal as the Azure AD administrator of the target AAD.
  • Open the Azure Active Directory blade.
  • Go to the Users section.
  • Click the + New guest user button at the top of the blade.
  • Invite your Microsoft Account to the Azure Active Directory.

2. Accept the invitation of your Microsoft Account to AAD

Now you have to accept the invitation…

  • You will receive an invitation e-mail to the mailbox associated with your Microsoft Account.
  • Do not click the Accept Invitation button from your e-mail client as it usually opens the web page in your browser where you are logged in using your Organizational Account and the invitation acceptance will fail.
  • Instead, copy the target URL of the button and open it in a New incognito window  (or In-private window or whatever it is called in your browser). (Alternatively you can sign out from your Organizational Account.)
  • Login using your Microsoft Account when asked for the credentials.
  • After accepting the invitation you will probably end up at the Applications page of the AAD (often empty), which might be a little confusing, but the association is done. You can close this browser window.

3. Change the directory of the subscription

Now you can change the directory of the subscription:

  • Sign in to Azure Portal using your Microsoft Account.
  • Navigate to your subscription and open the Subscriptions blade (you can type “subscription” in the search box).
  • Click the Change directory button in the top-row of the blade.
  • In the Change the directory panel you should have an option to select your Azure AD as a target directory for your subscription.
  • Confirm the change (Change button below).

Now you have to wait up to 10 minutes for the change to take effect.

4. Add permissions to your Organizational Account

To be able to manage the subscription by your Organizational Account, you have to add permissions to it (still signed in with the original Microsoft Account).

  • In the Subscription blade switch to the Access control (AIM) section.
  • Add your Organizational Account with an Owner role to the subscription level.
  • Right-click the Organizational Account added and click Add as co-administrator in the context menu. (An optional step for legacy scenarios where the co-administrator privilege is still needed).

5. Done

  • Sign-out from your Microsoft Account and sign up using your Organizational Account to verify you are able to manage your subscription from there.

iTunes – high CPU usage on Windows

My iTunes (currently 12.7.3.46) consumes ~25-30% CPU whenever I listen to any music.

The only trick I found to resolve this is to switch it to the “Miniplayer mode”, e.g. using Ctrl+Shift+M keyboard shortcut (use the same shortcut to switch back).

It has to be a weird glitch in iTunes, but the CPU usage almost immediately drops to 1-2% CPU.

How to change the password for your SendGrid account created from Azure

Short Story

Currently the only way is to use the forgot password feature on the SendGrid login page. The reset-password link is delivered to the mailbox associated with your SendGrid account (be sure to set this e-mail in advance).

Long Story

SendGrid is currently one of the few possibilities you have in Azure to send e-mails from your application. If you create your SendGrid account from Azure you can start with a free plan with 25 000 free e-mails per month.

For SendGrid accounts created in Azure there used to be an option for Changing/Resetting your password:

…which is unfortunately not available any more.

Azure Support’s reply to my question:

Passwords and other secrets associated with Windows Azure Store are managed exclusively by the provider (like Sendgrid). Please request the reset/change of the password directly with SendGrid. Support contact information is almost always found on the provider’s web site main page.

Unfortunately, if you log-in to your SendGrid account created from Azure, the option to “edit” username/password is disabled (they do not have a separate UI for changing the password and they don’t want to allow you to change the username which associates the account with Azure):

Currently the only way to change your password for your SendGrid account created from Azure is to use the “forgot password” feature from SendGrid login page:

Please note that you’ll need to enter the account username (not email address) for this form to work.

The reset-password link is delivered to the mailbox associated with your SendGrid account (be sure to set this e-mail in advance in Account Details).

Azure SQL: The database ‘tempdb’ has reached its size quota. Partition or delete data, drop indexes, or consult the documentation for possible resolutions. (Microsoft SQL Server, Error: 40544)

On one of the projects I’m involved in, whatever we wanted to do with our Azure SQL DB (V12), we got this error:

The database ‘tempdb’ has reached its size quota. Partition or delete data, drop indexes, or consult the documentation for possible resolutions. (Microsoft SQL Server, Error: 40544)

As there is not much to do in such situation we asked Microsoft Azure Support for assistance and this is their reply (saved here for further reference):

If you experience the TempDB full issue again, then please leverage the DMVs below and look for active transactions which are taking maximum TempDB space. For a long term fix, I would recommend tuning those queries to use less temp space and if the issue is being caused by multiple queries running concurrently then serialize the workload to not consume all available TempDB space. Here are the queries that will give you insight into which queries are causing this:

Query to get Used and Free Space in TempDB
Note: This can be misleading as it doesn’t include free space up to max size

SELECT
SUM(allocated_extent_page_count) AS [used pages],
(SUM(allocated_extent_page_count)*1.0/128) AS [used space in MB],
SUM(unallocated_extent_page_count) AS [free pages],
(SUM(unallocated_extent_page_count)*1.0/128) AS [free space in MB]
FROM tempdb.sys.dm_db_file_space_usage;

Retrieving information about which clients (connected to current database) are using TempDB with open transactions

Checking if tempDB has an active transaction

Examine log_reuse_wait_desc from sys.databases if you see ACTIVE_TRANSACTION this could mean there is a long running active transaction in tempdb that is blocking log flush =>

Check for active transaction on tempDB

select log_reuse_wait_desc, * from sys.databases where name = 'tempdb'

select d.name, d.log_reuse_wait_desc, t.* from sys.dm_tran_locks t inner join sys.databases d on t.resource_database_id = d.database_id

Few more docs about optimizing temp DB –
https://docs.microsoft.com/en-us/sql/relational-databases/databases/tempdb-database

https://technet.microsoft.com/en-us/library/ms190768(v=sql.105).aspx

Additionally, the higher the pricing tier, your database would have more tempdb space as well.
