I was investigating an issue in SharePoint 2013 where we got an error while using #hashtags in our Newsfeed textarea.
The tagging service is currently unvailable. Please try again later.
We have three web applications and two managed metadata service applications in this scenario.
- Web App1 – Connected to Managed Metadata 1
- Web App2 – Connected to Managed Metadata 1
- Web App3 – Connected to Managed Metadata 2
We have set Managed Metadata 1 as the default Service Applications for keywords and didn’t check this for Managed Metadata 2 because we were currently only using the content type hub for this web app.
After some testing we saw that this issue was occurring because we didn’t check ‘This service is the default storage location for Keywords’ at the Managed Metadata 2 Proxy properties
Select the first option and you will be able to use the tagging service with the hashtags located in the Managed Metadata Service Application.
