Cumulative Update 6 (CU6) for Exchange Server 2016 will be released soon^TM, but before that happens, I wanted to make you aware of a behavior change in item recovery that is shipping in CU6.  Hopefully this information will aid you in your planning, testing, and deployment of CU6.

Item Recovery

Prior to Exchange 2010, we had the Dumpster 1.0, which was essentially a view stored per folder. Items in the dumpster stayed in the folder where they were soft-deleted (shift-delete or delete from Deleted Items) and were stamped with the ptagDeletedOnFlag flag. These items were special-cased in the store to be excluded from normal Outlook views and quotas. This design also meant that when a user wanted to recover the item, it was restored to its original folder.

Usually, when we add a computer to a security group, we need to restart in order for the computer to see that it is now a member of this group. To bypass this, we can delete the system’s Kerberos ticket and run GPUpdate.

Usually, the Exchange external Autodiscover DNS entity is configured as a regular A or CNAME record. In some cases, a service record (SRV) is used instead. Here is a simple syntax of quickly querying for the SRV record:

During Cloud migration projects we ofter get questions similar to this:

“OK, we’ve moved to Office 365? Now what? How our Multifunction Device will send emails?”

I hope this blog post will help to understand what options are available to address the situation with Multifunction Device and any other devices and applications that should send emails through a corporate messaging system.
