Hello Meriem Djouaher, Thanks for reaching out! When a user tries to view free/busy information for a remote user, the free/busy information isn't displayed. Instead, the user may experience one or more of the following symptoms:
- The free/busy information for the remote user is displayed as number sign (#) characters in the Calendar.
- In Outlook Web App, "error 5037" is displayed.
- The Microsoft Outlook <FileName>-fb.log and <FileName>-as.log files contain an error message that resembles the following:
-
