address list not work at all device (the connections to microsoft exchange is unavailable)

Hi

we have very serious problem with exchange 2019 from the strart in our office and is that the address list doesn't work at any pc even with the server itself(shows" the connections to microsoft exchange is unavailable") but in owa address list work fine. we have searched a lot for this problem on internet and non of them worked.

Here is what we committed already :

1.check , renew and assign exchange certificates with all possible common name and dns names specifically autodiscover name to four smtp,iis,imap,pop sevices.

2.delete the related vm completely and recovered the exchange to last available verson 'cu7' same previously domain and that works completely fine but with same issue .

3.tied exchange testconnectivty tool but because our server isn't available for public the tool started with dnsrecord errors.

4.reinstalled various versions of outlook and replace multi time the out look profile .

plz help the only solution that we got is reinstalling the whole domain!

It could be alot of things unfortunately.

Start with the basics:

What is set for via Powershell:

 get-offlineaddressbook | FL 

Run in Powershell:

 get-offlineaddressbook | update-offlineaddressbook

Then Check on the server :

%ExchangeInstallPath%ClientAccess\OAB\<OAB GUID>

there should be updated files there. ( I assume one server)


If there are updated files there, then try to download from the client deleting any existing files:



Delete any and all *.oab files on the client workstation under C:\Users\%username%\AppData\Local\Microsoft\Outlook
then:
Send/Receive> Send/Receive Groups-> Download Address Book

If it still doesnt work or the OAB files on the server arent updating, report that back here

Your OAB is not being updated or hasn't changed in almost two years :)

Restart the Mailbox Assistant service on the server and see if the files are regenerated and that whenchanged date is updated and try to download the OAB from Outlook.

If not:
Try creating a new Offline Address Book, its real simple and easy to test:

https://docs.microsoft.com/en-us/exchange/address-books/offline-address-books/create-offline-address-book

 New-OfflineAddressBook -Name "OAB_Contoso" -AddressLists "\Default Global Address List"

Then:
Set the mailbox database to use that new OAB:

 Set-MailboxDatabase "Mailbox Database01" -OfflineAddressBook "OAB_Contoso" 

Then:
get-offlineaddressbook | update-offlineaddressbook

Then:

Restart the Mailbox Assistant service

Then:

See if the files are created for the NEW OAB under the directory for the new OAB GUID

%ExchangeInstallPath%ClientAccess\OAB\<OAB GUID>

Wait about 15 minutes, then try to download the Offline Address Book from Outlook client.

Ok, now verify the permissions on that server OAB folder are correct:
Authenticated Users should have Read perms on that GUID folder:

When did this start and did it ever work?

i grant the "authenticated users " with full control for oab folder and surely inherited to all child objects but still stucked on processing...
and i checked C:\Users\Administrator\AppData\Local\Microsoft\Outlook ,there is no .oab file only one .ost .

When did this start? I see you have another thread open with issues.
How did you "delete the related vm completely and recovered the exchange to last available verson 'cu7"

What steps did you take?

Are all the services running?

 test-servicehealth

 Get-ServerComponentState -Identity <ServerName>

Any anti virus installed?

Is the BITs service running on the clients?

Did it ever work? its not easy to troubleshoot these, but sounds like that server has bigger issues.

Hi my friend.
I had a problem similar to yours. After reviewing the problem for a few days and Event Viewer, I encountered the following error:
Protocol /mapi/nspi failed to process request from identity NT AUTHORITY\SYSTEM. Exception: Microsoft.Exchange.Security.Authentication.BackendRehydrationException: Rehydration failed. Reason: Source server 'NT AUTHORITY\SYSTEM' does not have token serialization permission.

Finally, I solved the problem with the following command in exchange management shell:

Get-ClientAccessServer | Add-ADPermission -AccessRights ExtendedRight -ExtendedRights "ms-Exch-EPI-Token-Serialization", "ms-Exch-EPI-Impersonation" -User "NT AUTHORITY\SYSTEM"

I hope I helped well.
