Shared Mailbox Permissions

Permissions of shared mailboxes did not migrate

Document delegated permissions

We used PowerShell to quickly add back the necessary permissions

Configure Mobile Phones

• Multiple mobile device models• Users Do Not Read Instructions

• Document the most common devices• Email instructions to your users• Email instructions to your users … Again• Be ready for the oddball or uncommon device

that you don’t know how to configure

Outlook Version 2010

SCCM did not update all PC’s

Outlook would not connect to O365

Be prepared to manually apply updates

This occurred on about 5% of our systems

Outlook Web Access

Outlook.com blocked by customersField techs could not access OWA

Used the Global Federated Services URL

Routing and Email Addresses

UPN (User Principal Name)User’s email address

Routing address

We manually verified these settings in each user object

A number of accounts were incorrect

Manual verification made the migration more smooth

Mailbox “Mail Flow” Settings

Mail Flow settings may not migrate

Dan.Cooper@esi.net forwarded to dan.cooper@gisx.com

Manually reconfigured mail flow settings

We learned of this on the fly

Outlook Rules

OLD Outlook rules reactivated

Had to convince users that IT wasn’t screwing with them

Managing Distribution Lists

“Managed by” no longer works

Since the migration – IT manages membership for all distribution lists

PowerShell Management

Most admin functions are performed via PowerShell

Just prepare yourself if you are strictly a GUI person

PowerShell is easy … Once you know what you are doing

We have scripts you can modify and use for your organization

ConnectWise

Mailbox delegation and SMTP configuration

ConnectWise works just fine

We have the configuration settings

Ask me if you need them

Dynamics CRM

Email Router Configuration

Installed and configured the CRM Email Router

Tetyana with Catapult helped ESI

Bandwidth for Data Migration

No IssueInformational Only

We were able to migrate 45 GB in 6 hours across a 45 MB pipe

This was consistent for each day we migrated mailboxes

The End

Wake up! It’s lunch time
