Mailboxes displaying GUID instead of Display Name due to change in Microsoft naming convention -
説明
Microsoft changed the Name parameter associated with recipients within a tenant in Exchange Online, which results in mailboxes displaying mailbox names incorrectly. Instead of displaying the user's Display Name, a GUID is displayed instead.
Here is an example:
Before changes are implemented:
DisplayName: Jeff Smith
Name: Jeff Smith
Alias: jsmith
DistinguishedName: CN= Jeff Smith,OU=(tenant).onmicrosoft.com, OU=Microsoft Exchange Hosted Organizations, DC=NAMP283A001, DC=PROD,DC=OUTLOOK, DC=COM
ExternalDirectoryObjectId: 12313c53-fff7-46d4-8b83-71fb317d1853
After changes are implemented:
DisplayName: Jeff Smith
Name: 12313c53-fff7-46d4-8b83-71fb317d1853
Alias: jsmith
DistinguishedName: CN= 12313c53-fff7-46d4-8b83-71fb317d1853, OU=(tenant).onmicrosoft.com, OU=Microsoft Exchange Hosted Organizations, DC=NAMP283A001, DC=PROD, DC=OUTLOOK, DC=COM
