Office 365

REQUIRED: Outlook 2011 (Mac) Pre-Migration Steps

This document walks users of Outlook 2011 through the checks required before a mailbox can be migrated from AEMS to Office 365. The following steps must be reviewed thoroughly:

Removing large items before email migration for Outlook for Mac 2011:

  1. Click inside the Search This Folder box in the top-right corner of the Outlook 2011 window. The Search ribbon will appear underneath the Search This Folder box.

  2. Click All Mail and then click Advanced. The search criteria fields will appear underneath the Search ribbon.

  3. In the first menu, choose Size. In the second menu, choose Is Greater Than, and in the text box, enter 20000.

  4. Messages larger than 20 MB will appear in the list. Select them and either delete them if they are not needed, or move them to a local storage space.

Deleted Items Warning

Large Deleted Items Folders
The migration process can be slowed down if your mailbox's Deleted Items folder is large in size. If you don't need these messages, emptying your Deleted Items folder can speed up the migration. To do this, right-click (control-click in Mac OS X) your Deleted Items folder and select Empty Folder or Erase Deleted Items.

Note: If the above search instructions identified any large items in your mailbox, this action is necessary to prevent issues migrating your mailbox.

30-day Deleted Items Timer and Functionality
Once your mailbox has finished the migration process, a 30-day timer will start, and all messages migrated will be permanently deleted in 30 days. Moving forward, all messages in the Deleted Items folder older than 30 days will be permanently removed.

If there are any messages in that folder that you may need, please restore them to your mailbox before this timer is up.

Purge Recover Deleted Items Folder

If you identified any large items using the above steps, permanently removing them from the Recover Deleted Items folder is needed to prevent any migration issues. This feature is not available in Outlook 2011 but can be done using the Outlook Web App by following the instructions available here:

Resource Calendars and Accounts
