ISSUE
Location field update for a single instance of a recurring event, using Exchange On-Prem Mailboxes, doesn't sync with Outlook Mobile Calendar.
DETAILS
While syncing events in Outlook Mobile with Exchange On-Prem Mailbox, updates to the event's location are partially saved. The Enhanced Location field responsible for updated locations isn't properly updated during sync.
As a result, the old location appears when reading the event, giving the impression that the location isn't updated in Outlook Mobile.
This issue is limited only to Exchange On-Prem Mailboxes with Hybrid Modern Authentication implementation.
STATUS: FEATURE GAP
This is a feature gap in the Exchange Online environment cache system used by Outlook Mobile to sync data from Exchange On-Prem. Per evaluation, we won't have this feature in the near future.
WORKAROUND
Check the event location from other clients, such as Outlook for Windows, Outlook on the web, native ActiveSync client.
