Email Proxy (Alias) Addresses Suddenly Capped at 200?

UPDATE: Unwelcome resolution.

The only option for any kind of solution was to create multiple Distribution Groups for individuals requiring more than 200 "proxy addresses" or aliases. It's the most stupid thing I've ever had to do in all of my 30 years of administration experience. I now have four, count 'em, FOUR distribution groups specifically for ME that contain 100 or more addresses in unequal alphabetic divisions.

I now accept that there may have been a limit previously however I was not even close to halfway at only 416 of some supposedly high number of 1200-1300 or more. Suddenly I was shown this popup in September 2016 that mandated no more than 200 addresses were acceptable after I had been well over 350 for years so I know this was a conscious decision by a bureaucrat somewhere at Microsoft. There is no other possible conclusion. Furthermore, I sincerely doubt this was carefully considered whatsoever.

There has to be a better way — if sensibility could ever prevail! If only Microsoft could find some way to incorporate WILDCARD addresses, this problem would hardly occur. Yes, I've seen the supposed "workarounds" for wildcards but it shouldn't be required. As always with Microsoft, I am once again disappointed, almost as much as with the Edge "browser" that some bureaucrat at Microsoft laughingly thought was a good idea. Sigh.
