Office 365

REQUIRED: Outlook Web App - Pre-Migration Checklist

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

Deciding How To Handle Each Message

For each message 25 MB or larger, decide whether to save the attachments. To save an attachment, click on its name while viewing the message. Follow your browser's method of saving a file to your hard drive.

Then, to delete a message from the list of messages in a folder, click to highlight it, then click Delete in the toolbar just above the Search box. Or, if the message is open in its own window, click the X in the toolbar.

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.

Public Folder Information

Please let your Technical Support Contact (TSC) know of any Public Folders you currently manage.

Resource Calendars and Accounts

We would like to migrate any rooms or resource accounts you manage alongside your mailbox so your workflow is not interrupted. Please let your Technical Support Contact (TSC) of any resources you manage.

Additional Resources for Migration Process

You will have received notice of when your migration date is. On that day or anytime before, please make note of the following resources for when your migration process is occurring.
