Well.... I have not deployed 2016 yet, however I am running 2007, skipped 2010, deployed 2013, and am running in hybrid with O365. One of the reasons for the hybrid was to get free/busy rich coexistence between 2007 and O365 until we got everyone migrated to O365.
As it turns out, the best I could get was free/busy (where the calendar literally would only show that someone was busy, but would not give details), but for our purposes that was good enough. This was a limitation between 2007 and newer versions of Exchange, per Microsoft. There are a number of things that it could be. I suggest having a look at this article - it does not address 2016, however a lot of what is in there will most likely still be applicable from a troubleshooting standpoint. If you don't have a techtarget account, it is free, and they don't spam you too much, unless you sign up for everything under the sun: http://searchexchange.techtarget.com/tip/Troubleshooting-Exchange-2010-free-busy-issues HTH, Jonathan From: [email protected] [mailto:[email protected]] On Behalf Of Alice Goodman Sent: Friday, April 22, 2016 9:01 PM To: [email protected] Subject: [Exchange] See Free/Busy from Exchange 2010/Exchange 2016 shared environment? We are on Exchange 2010 SP3 Ru13. We put Exchange 2016 CU1 into production finally this week but have moved only one test mailbox to it so far. We don't have a test email system so I guess you can call this "testing in production". :) I need to see what the changes and updates and limitations are, as we never used 2013. And eventually we will go E2016 / O365 Hybrid. I thought we would be able to see free/busy information but the when I look from my 2010 system at the calendar on the 2016 mailbox, I see blank. I know there are meetings on there. What did I miss?
