Hi @Dalton
Welcome to our forum!
It seems the issue might be related to the Offline Address Book (OAB) not updating in the old version of Outlook. Here are a few steps you can try to resolve this:
- Update the Offline Address Book:
- In the old version of Outlook, go to Send/Receive > Send/Receive Groups > Download Address Book.
- Ensure that the Download changes since last Send/Receive option is checked, and then click OK.
- Force Update the Global Address List (GAL):
- If the above step doesn't work, you might need to update the GAL on the server side. You can do this by running the following PowerShell command in the Exchange Management Shell:
Update-GlobalAddressList -Identity "Default Global Address List"
- After updating the GAL, you can force an update of the OAB by running:
Update-OfflineAddressBook -Identity "Default Offline Address Book"
- If the above step doesn't work, you might need to update the GAL on the server side. You can do this by running the following PowerShell command in the Exchange Management Shell:
- Check Cached Mode:
- Ensure that Outlook is running in Cached Exchange Mode. If it is, try switching to Online Mode temporarily to see if the changes reflect. You can do this by going to File > Account Settings > Account Settings > Change > uncheck Use Cached Exchange Mode.
- Wait for Synchronization:
- Sometimes, it might take up to 24 hours for changes to propagate across all services.
If these steps don't resolve the issue, it might be helpful to check if the job titles are correctly updated in the Exchange Admin Center under Recipients > Mailboxes > select a mailbox > Manage organization information.
Hope it helps.
