In current versions of Connection the answer is yes. Documentation suggests that this was not always the case; however, I'm not sure which version added it. At a high level you need to:
- Run a BAT Export of the mailboxes
- Pair down the CSV file to only the Alias column (primary key for the update operation), CcmId, and LdapCcmUserID columns.
- Replace the GUID shown in CcmID with %null% (including the percent signs). The value shown is the GUID of the End User object in CUCM that the mailbox is integrated with. Clearing this field breaks the integration.
- Populate the LdapCcmUserID column with the username. In most designs you can simply copy the Alias column value over.
- Run a BAT Update of the mailbox. You will now see that it is integrated with LDAP instead of AXL.
As always, perform the BAT Update on a small sampling of mailboxes first to prove that it is working as intended.
