Available scenarios of Exchange to Office 365 Migration

With the popularity of Office 365 constantly growing, there are few administrators who did not at least consider moving from their on-premises Exchange server to Microsoft’s Cloud. Especially now, when the extended support for Exchange 2007 is inevitably going to end in 2017, Exchange to Office 365 migration is likely to be a common topic. As moving mailboxes is never an easy task, there are quite a few consequences which have to be taken into consideration before jumping into the new environment.

First of all, you have to remember that Office 365 has some storage limits which have to be taken into consideration. All mailboxes types, including public folders and shared mailboxes, can store up to 50 GB of data. If in your organizations there are public folders or mailboxes which exceed this size, you might want to archive some content.

Secondly, moving to Office 365 requires the source and target environment to be thoroughly prepared before the migration proper can be started.

There is a number of native options available for those who wish to move from their on-premises Exchange to the Online version:

  • Cutover Migration
  • Staged Migration
  • Hybrid Deployment*
  • Office 365 Import Service

*Does not apply to Exchange 2007 and older versions

How to quickly verify if Autodiscover is working

Autodiscover is an Exchange service which, after successful configuration, helps admins and users save tons of time. Thanks to Autodiscover, Outlook clients are automatically configured, after as little as entering user’s e-mail address and password upon first login. Its job does not end there, it is required to ensure Outlook-Exchange connectivity later on. Therefore, it is crucial to diagnose problems with the service as quickly as they occur. In this guide I will show 2 quick and easy ways to do that.

Using Powershell

Checking Autodiscover connection for a user is as simple as using a single cmdlet:Test-OutlookWebServices for the user you want to diagnose, i.e.

Email disclaimers on Microsoft Exchange Server’s side

(First published Jan 16, 2014)

Server sided email disclaimers belong to one of the most desired features among server administrators. Although the need for this functionality has been consistently increasing throughout the past years, Microsoft still hasn’t disclosed a robust built-in Exchange Server mechanism that would fully satisfy the needs of IT professionals.

How to recover deleted emails in Office 365?

Although mailbox data in Office 365 is fairly secure, it does not mean it is protected from deleting. Users, either by accident or on purpose, can remove their emails from Inbox and Deleted Items folder or even purge them from Recoverable Items folder. What’s more, retention policies can exist, which live only for deleting certain emails from users’ mailboxes. Of course, Office 365 gives you a plan B, just in case you would need to recover deleted emails. This plan, however, only works when the time gap between deletion and recovery is not too big.
