Hi @WaleedAhmad-3337 ,

Based on my knowledge, "This Computer Only" appears when the outlook has been configured with IMAP.

Please try the below,
1.Configure a new outlook profile with MAPI and with cached mode enabled
2.Once profile is configured, go to system tray -> outlook -> press ctrl+right click on outlook icon -> click on "Connection Status" to confirm the connectivity
3.Use the same method as step 2 and click on "Test email autoconfiguration" -> uncheck "use guessmart" and "secure guessmart authentication" and click on "Test"
4.Check if the OAB URL has been retireved
5.Go to File -> Account settings -> Download address book and click on "Ok"
6.Verify the Address book

If still having issue, check the Address book in Exchange 2019,

Get-OfflineAddressBook

To verify the system mailbox,
Get-Mailbox -Arbitration

Hi Ashok,

Thanks for the solution. But getting issues to configure the profile with mapi. The Active domain controller name is .com and exchange email addresses are .com.sa. We have a ssl certificate for com.sa. Kindly let me know how i will rename the Active Directory Domain controller to .com.sa or let me know the exact requirement for MAPI configuration in exchange server 2019 step by step.

Hi @WaleedAhmad-3337 ,

Its not recommended to rename Active directory domain for the Exchange services. Renaming AD domain involves risks and lot of things to be consider.

For outlook to be configured with Exchange, please follow the below steps ,

1.Configure the Virtual directories
2.Import certificate and assign services (3rd party wildcard or SAN certificate)
3.DNS entries
4.Set AutodiscoverServiceInternalUri using Set-ClientAccessService

Also, is the GAL working when you login to OWA?

Hi @WaleedAhmad-3337 ,
All users have this issue or only specific have?
What is the specific error you encountered?
How is your email address configured? Have you set a new email address policy?

1.Please check whether the UPN of the mailbox object has changed. According to my test, I manually modified the Alias of the user mailbox, but when configuring the Outlook profile, I still used the UPN address for configuration and it can be configured successfully.

2.According to my research, renaming the Active Directory Domain Controller is a very complicated thing. Since there are many objects in AD, there are also great risks in the process of renaming, so it is not recommended that you rename AD DC.

3.Please run the following command to check whether the Autodiscover url is correct:

 Get-ClientAccessservice | fl *uri*
