Hi,<br />
I have an issue with our Exchange Admin Centre.<br />
When attempting configuration changes to mailboxes in EAC, running into several issues:<br />
- The Organizational Units (OUs) are not showing up<br />
- When clicking 'browse' to see a list of users, nothing shows up<br />
- When attempting to run reports, getting errors<br />
Tried with IE and Chrome.<br />
We are running Exchange 2013 and the server has already been restarted but did not resolve the issue.

Hi,
I have an issue with our Exchange Admin Centre.
When attempting configuration changes to mailboxes in EAC, running into several issues:
- The Organizational Units (OUs) are not showing up
- When clicking 'browse' to see a list of users, nothing shows up
- When attempting to run reports, getting errors
Tried with IE and Chrome.
We are running Exchange 2013 and the server has already been restarted but did not resolve the issue.

Web browsers are applications used primarily to display documents, files and media from the Internet, identified by a Uniform Resource Identifier (URI) that can be a page, image, video or other file. Some browsers require the use of add-ons or extensions to safely render the information they receive; others have systems built into them to perform the same functions.
