Once we know the error message, it’s much easier to resolve the issue. These steps are important in order for us to see the relevant message error for Free/Busy issues. Please see Part 1 for discussion of directionality. Where can we see actual Free/Busy error message?įirst, we need to understand in which direction we have a lookup problem. This F/B test from SARA covers mostly cloud to cloud scenarios but I recommend it here because it does connectivity and additional checks on tenant, licensing and Autodiscover. Due to underlying complexity of it all, this is not a completely reliable way of determining the cause of free/busy issues in Hybrid Deployments, but it is a good start when troubleshooting. I would also like to mention that there is a Free/Busy troubleshooter in Beta version, incorporated into SARA tool (Microsoft Support and Recovery Assistant for Office 365) which you can download it from here : Open SARA and select Outlook, click Next, select I’m having problems with my calendar, input email address and password of the source mailbox (cloud mailbox if direction not working is cloud > on-premises) and then select I can’t see when someone is free or busy. Therefore, don’t be surprised if you see this test as green (successful) but Free/Busy is not working in your Hybrid Organization. It is, however not a relevant Free/Busy test per se, as it uses Basic authentication and not Federated authentication used in actual Free/Busy lookups. This Free/Busy test is useful for checking DNS records, Autodiscover and EWS connectivity issues, pre-authentication for Autodiscover or EWS requests. Before getting to actual Free/Busy errors it is worthy to know that there is a Free/Busy test on Remote Connectivity Analyzer, Office 365 tab that can help us with some configuration /functional issues. Instead we would need to take slightly more advanced steps to diagnose the issues by checking things like the Outlook logs, F12 Network tab, or Fiddler. You can often see an error message by hovering over hash marks, however we usually find that the error is not very specific. If they see the hash marks \\\\\\\ instead of seeing if the other user is free or busy, there is an issue.



Usually when a user creates a new meeting in Outlook on the web (OWA) or Outlook, clicks on Scheduling Assistant, adds his or her colleague to the meeting, they try to see when the user is available to meet. Before venturing forth, please make sure that you have seen Part 1 of this demystifying series! Here is the graphics we posted in the previous post use this as a reference for users that we will be referring to when troubleshooting: Do you really have a Free/Busy issue? In this second part of the Demystifying Hybrid Free/Busy, we will cover troubleshooting of Hybrid Free/Busy scenarios, more specifically – how and where to find an actual error that will indicate where the problem is.
