Tune Exchange Online (O365) Performance

To improve the speed of migration and reduce your organization’s bandwidth constraints for Exchange Online, consider the following:

  • Reduce mailbox sizes and always use cached mode
    • Smaller mailbox size improves migration speed. Cached Exchange Mode enables a better experience when you use an Exchange account. In this mode, a copy of your mailbox is saved on your computer. This copy provides quick access to your data, and it is frequently updated with the server that runs Microsoft Exchange.
  • Use the mailbox move capabilities with an Exchange hybrid deployment:
    • With an Exchange hybrid deployment, offline mail (in the form of .OST files) does not require re-download when migrating to Exchange Online. This significantly reduces your download bandwidth requirements. A hybrid deployment provides the seamless look and feel of a single Exchange organization between an on-premises Exchange organization and Exchange Online in Microsoft Office 365. In addition, a hybrid deployment can serve as an intermediate step to moving completely to an Exchange Online organization.
  • Schedule mailbox moves to occur during periods of low Internet traffic and low on-premises Exchange use:
    • When scheduling moves, migration requests are submitted to the mailbox replication proxy and may not take place immediately.

Force AAD Connect Synchronization Cycle

The scheduler will run by default run every 30 minutes. In some cases you might want to run a sync cycle in between the scheduled cycles or you need to run a different type.

Delta Sync Cycle
It could be that you have an urgent change which must be synchronized immediately which is why you need to manually run a cycle. If you need to manually run a cycle, then from PowerShell run:

Start-ADSyncSyncCycle -PolicyType Delta

Full Sync Cycle
If you have made one of the following configuration changes, you need to run a full sync cycle (a.k.a. Initial):

  • Added more objects or attributes to be imported from a source directory
  • Made changes to the Synchronization rules
  • Changed filtering so a different number of objects should be included (e.g. Adding a new OU to the filter)

If you have made one of these changes, then you need to run a full sync cycle so the sync engine has the opportunity to reconsolidate the connector spaces. To initiate a full sync cycle, run:

Start-ADSyncSyncCycle -PolicyType Initial

Interested in deploying multi-factor authentication for your business? It is now part of Office 365

Multi-factor authentication is now part of Office 365 and available for all users. Any of the following may be used for the second factor of authentication.

  1. Call my mobile phone. The user receives a phone call that asks them to press the pound key. Once the pound key is pressed, the user is logged in.
  2. Text code to my mobile phone. The user receives a text message containing a six-digit code that they must enter into the portal.
  3. Call my office phone. This is the same as Call my mobile phone, but it enables the user to select a different phone if they do not have their mobile phone with them.
  4. Notify me through app. The user configured a smartphone app and they receive a notification in the app that they must confirm the login. Smartphone apps are available for Windows Phone, iPhone, and Android devices.
  5. Show one-time code in app. The same smartphone app is used. Instead of receiving a notification, the user starts the app and enters the six-digit code from the app into the portal.
