Outlook & Teams after migration
Review what to expect in Outlook and Teams and complete any steps that apply to you.
Historical Centerstone East User Accounts showing up in Outlook
After the migration, old Centerstone East accounts may still appear in Outlook temporarily. For example, when creating a new email and typing a Centerstone East user’s name, the name may appear twice. Do not use the account ending in @centerstoneorg.onmicrosoft.com; instead, use the account with the @Centerstone.org domain. The old account should be removed within the next few days.
Removing Autocomplete Entries from Outlook
Centerstone West will most likely have older, cached addresses that are in autocomplete in the “To” address when composing or replying to e-mails. You will need to manually delete any addresses that end with @centerstoneorg.onmicrosoft.com or @migration.brightli.biz e-mail addresses. You will need to select the “x” next to those names to clear them out of your cache.
Outlook Calendar Meetings
If a Centerstone East user was assigned as a delegate for your Outlook calendar or inbox, you will need to add them again.
Delegates and Shared Inboxes will need to be reassigned
If a Centerstone East user was assigned as a delegate for your Outlook calendar or inbox, you will need to add them again.
Rules recreation
Users with accounts in both the Centerstone East and Centerstone West tenants may have lost their Outlook rules during the migration and will need to recreate them.
Missing Members in Centerstone East Distribution Lists
Centerstone West users assigned to Centerstone East distribution lists were removed during the migration and will need to be added back.
Outlook Appointments Created by Centerstone East Users That Include Teams
If a Centerstone East user created a meeting before the migration that included a Teams virtual conference option, participants will no longer be able to join because the original meeting ID is no longer valid. To resolve this, delete and resend the meeting so a new Teams meeting ID is generated and shared with participants.
Historical Centerstone East User Accounts
After the Centerstone East migration, any Microsoft Teams team, chat, or channel that included a Centerstone East user must have that user re-added. The migration created a new Teams account for each user, while the old account is being removed over time, the old account will appear with [External] next to the user’s original name.
If you send a message to the old Centerstone East account, you will receive an error, and the user will not receive the message. Select the user name that has the associated picture and/or account that has the @centerstone.org domain, not the @centerstoneorg.onmicrosoft.com.
Note, group chats that included a Centerstone East user, will need to re-add the user with the @centerstone.org domain after migration.
Because new accounts were created, existing chat sessions that include Centerstone East users will need to have those users re-added.
Tenant Access Issue
When you open Teams, you may temporarily see an issue icon next to your name. This is expected for the next few days and indicates that Teams is still showing the old Centerstone.org account, which is no longer available. We cannot remove that account immediately, but it will disappear automatically after a few days.
