Exchange Admin Center language

Depending on your computer language settings, Exchange Admin Center can take those and open in a language you actually don't want to use.
You'll Google that this can be changed if administrator/ admin user has mailbox by openening OWA settings and changing Regional parameters.

But usually Admin user does not have mailbox or you don't want her/him to have it. You will search again and find that you can add mkt=en-US (as an example) to the URL of the Exchange Admin Center (https://yourexchangehostname/ecp?ExchClientVer=15&mkt=en-US)

Third option you have is opening Internet Explorer settings (I am using Windows 2016)


Click languagesClick Set Language Preferences

Add language you want to use by clicking Add language
Use Move up or Move Down options to put desired language on topClose Internet ExplorerOpen it again and login again to Exchange Admin Center

MacOS Sierra Time Machine - Preparing backup... forever to Synology

Your password couldn't be changed in OWA 2013

Your users might get an error while changing their password through Outlook WebApp (Exchange 2013) stating:
Your password couldn't be changed. Make sure the old password you typed is correct and that the new password meets the minimmum security requirements.


On the other hand password change through Windows in Site 2 is successful. Password Group Policy is OK and it is working in primary site.

Setup:
Two sites | Two domain controllers, each in its own site

If Exchange servers are in other site than users trying to change their password, open port 464 in firewall for Exchange servers to let Exchange communicate with domain controller in other site.

The Windows component Server-Gui-Mgmt-Infra isn't installed on this computer and needs to be installed before Exchange setup

You get this error "The Windows component Server-Gui-Mgmt-Infra isn't installed on this computer and needs to be installed before Exchange setup" when you try to install Exchange 2016 on Windows 2016 server. Exchange 2016 pre CU3 does not support Windows 2016, therefore you need to download Exchange 2016 CU3, which is in fact full copy of Exchange 2016 server in order to install it on Windows 2016 machine.
