Hi,

after migration from Lotus Notes to Exchange 2013 some users experience the followings:

- opening a single instance of a meeting series in the outlook calendar, the LegacyExchangeDN of the organizer shows up in the Organizer field instead of the organizer's display name.

- if you hover over the LegacyExchangeDN with the mouse it resolves properly to the organizers contact card

- If you open the whole series the Organizer Field shows properly the Display Name of the organizer

- The organizer shows properly with display name in the scheduling assistant as well

- The problem also shows in OWA

- So far it is true for migrated meeting series only.

Any idea of why is this happening and how could it be prevented would be appreciated. 

Hi ,

Thank you for your question.

Did this issue occur all users or the specific users?

Are there any errors when we migrate Exchange from Lotus?

Are there any errors in application log on Exchange server when we create a meeting?

We could update outlook to the latest updates then rebuild the profile to check if the issue persist.

Then we could update Exchange to new version to check if the issue persist.

If there are any questions regarding this issue, please be free to let me know. 

Best Regard,

Jim
