I'm not able to access the term store from Site Actions --> Site setting --> Term Store Management.

Below is the error that I receive:

The Managed Metadata Service or Connection is currently not available. The Application Pool or Managed Metadata Web Service may not have been started. Please Contact your Administrator.

This is in my local environment, hence I'm the administrator for the site collection and the term store as well.

Few days back I was able to access the term store. I even created the Term sets and Term values in it.

But now its not accessible. Its not accessible from Central Admin as well.

Already tried the steps on the below link:


Below is the ULS entry:

  • Make sure managed metadata service is running. – Amal Hashim Dec 2 '14 at 9:43

    Yes, Managed Metadata service is running. Below are the steps that I have already tried. Solution 1: Check your IIS and check IUSR is added in Anonymous Authentication. Solution 2: Could be a permission issue on Managed Metadata Service Application Solution 3: Issue could be Managed Metadata Service wouldn't have started. Solution 4: Low Disk Space in database Server. Check your disk space in database server. – SP_Tech Dec 2 '14 at 9:51
  • When I go to Central Admin --> Application Management --> Manage service applications --> Select Managed Metadata Service (Managed Metadata Service connection) and click properties.... I get an error... ERROR: the operation has timed out: Correlation ID: 23e487b0-1cca-4360-8bd6-d4c8fd74e437. I was not able to find much information on the correlation ID. – SP_Tech Dec 2 '14 at 12:55
  • I would suggest you delete that service and create a new one. – Amal Hashim Dec 2 '14 at 13:01
  • Yesterday, I was not able to open the default managed metadata service from the central admin and site collection as well. Today, as you told, after creating a new metadata service, now I'm able to access both the services (term store) from Central Admin but not from any site collection. – SP_Tech Dec 3 '14 at 5:55
