Hi all,
We have 2 Exchange 2016 servers which have been running for more than 2 years now.
We have applied several CU during this period and now we can see that significative amont of disk space is used by old OWA versions (in %ExchangeInstallPath%ClientAccess\Owa and %ExchangeInstallPath%ClientAccess\Owa\prem).
How can I safely remove theses old versions ?
Thank you.
Regards,
Hi all,
All is right since our Exchange servers last reboot.
Now one question remains : how should I deal with the old OWA versions located in \Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa ?
Thank you.
Regards,
Same way? Move , then test. If no issues, you can remove them.
