"We’re approaching the one-year anniversary of the release of Exchange Server 2013."
and it is almost like you did nothing for the entire year. users still dislike the new OWA interface regardless if it looks terrible on more supported platforms now. MAPI, Edge, and other services have been removed and features degraded. We don't even have a decent GUI interface anymore. Bugs still plague the product. We can't even install the base product into an existing Organization without it immediately breaking the client CAS connectivity and we have to drop to PS just to set the uri to null. Exchange appears to have regressed tremendously with this version. Now, even the CUs are not being released on time anymore and countless patches have been recalled.
yes, it's the one year anniversary and on premises Exchange is still in terrible awful shape. Agree with a previous poster that this is nothing to be proud of. I might add that I've never seen such shoddy work from the Exchange team before. This is not an anniversary to be proud of.
