This topic provides a list of known issues as well as methods to troubleshoot problems with free/busy interoperability.

Known Issues

  • Free/busy lookups don't work against Lotus Domino servers started as an application. To resolve this issue, start the Lotus Domino server as a Windows Service.

  • Meeting invitations sent from Lotus Notes 6.5.5 or greater display correctly in Microsoft Office Outlook, but the invitations include an iCal attachment. This attachment can be ignored.

  • Meeting invitations sent from Outlook lose attachments when routed to Lotus Notes.

  • Recurring meetings between Outlook and Lotus Notes users cannot be updated because the systems process recurring meetings differently. To update recurring meetings, cancel the original meeting and then create a new meeting.

  • Meeting requests with Rich Text created by Lotus Notes users are displayed as plain text by Outlook.

  • When a Lotus Notes 7.0.2 user creates a meeting and lists Outlook users, Notes does not always send the meeting to the first Outlook user. To resolve this issue, remove this user's name and add the user again.

  • Meetings scheduled by a Lotus Notes user and sent to Microsoft Office Outlook users always have the reminder set to 15 minutes prior to the meeting.

  • Meetings with a custom pattern (for example, first Tuesday, second Thursday) sent from a Lotus Notes user to Outlook users are converted to e-mail messages rather than a calendar item.

  • Exchange rooms are not available to Lotus Notes users when scheduling meetings.

  • The Free/Busy Connector is not able to access the Lotus Domino server running the Excalcon.exe task if that server is not correctly registered in DNS. If the server's common name doesn't match the computer's hostname, a DNS alias record must be created.

  • The Lotus Notes feature that moves a recurring meeting that falls on a weekend to a weekday is not supported in Exchange. The meeting will be listed on the scheduled date, even if the date is a Saturday or Sunday.

  • When the Mailbox server role and the Client Access server role are installed on the same Exchange 2007 server, you must disable Publicvdir SSL in order to perform free/busy lookups. To disable Publicvdir SSL, right-click My Computer, select Manage and then click Internet Information Services (IIS) Manager. Navigate to Web Sites/Default Web Site/Public, and then open the Properties dialog box. Switch to the Directory Security tab, and then click Secure Communications Edit. Clear the Require secure channel (SSL) option, and then click OK. Restart IIS by typing iisreset at the command prompt for this change to take effect.

  • Free/busy lookups don't work against Lotus Domino server started as an application. To resolve this issue, start the Lotus Domino server as a service.

  • Meeting invitations sent from Lotus Notes 6.5.5 or greater display correctly in Microsoft Office Outlook; however, the invitations include an additional iCal attachment. This attachment can be ignored.

  • Meeting invitations sent from Outlook lose attachments when routed to Lotus Notes.

  • Recurring meetings between Outlook and Lotus Notes users cannot be updated because the two systems process recurring meetings differently. To update recurring meetings, cancel the original meeting and then create a new meeting.

  • Meeting requests with Rich Text created by Lotus Notes users are displayed as plain text by Outlook.

  • Meeting counter proposals/propose new time between Outlook and Lotus Notes users do not work. Lotus Notes users receive a tentative acceptance rather than a counter proposal.

  • Microsoft Exchange does not support custom recurrence patterns for meetings. A meeting with custom recurrence sent from a Lotus Notes user to an Outlook user is displayed as an e-mail message in Outlook.

  • When there is no Free/Busy public folder, the following error occurs: Cannot find Exchange Server error when trying to create new Free/Busy Connector. This error prevents the Free/Busy Connector from being created. Create a free/busy public folder, and then create the Free/Busy Connector.

  • If Transporter is installed on an Exchange Server 2007 server with the Mailbox and the Client Access server roles, Free/Busy lookups won't work until Publicvdir SSL is disabled. To disable Publicvdir SSL, right-click My Computer, select Manage and then click Internet Information Services (IIS) Manager. Navigate to Web Sites/Default Web Site/Public, and then open the Properties dialog box. Click the Directory Security tab, and then click Secure Communications Edit. Clear the Require secure channel (SSL) option, and then click OK. Restart IIS by typing iisreset at the command prompt for this change to take effect.

  • When using Domino Web Access against a Domino 6.5.5 server to send meeting invitations, Outlook user names are not properly resolved. This does not affect functionality because users can still accept, decline, tentatively accept meeting requests, and reply to the sender.

  • Lotus Notes users who send meetings via a Domino 6.5.4 server may display Outlook user names strangely. This issue does not affect functionality.
