Hello

Please i need your help on this issue.

We are having an issue with free busy sharing between the ABCsideHealth .com and ABCmar- health.com

One of our user Rachel@ABCsideHealth .com is unable to see free busy information for cclodABC@mar-health.com and cashABC@mar -health.com.

Rachel@ABCsideHealth .com is using the new Outlook desktop client and has also tried outlook.microsoft.com with the same results.

Another user Ferg from ABCsideHealth .com can successfully see free busy information for the same recipients.

But today the reverse is successful cashABC@mar -health.com can see Rachel@ABCsideHealth .com free busy.
