LCS error An error has occurred. Please try again later. If the issue persists, please contact support with this Id: 859f43e3

I recently opened LCS and got following error when I clicked one of my D365FO environments:
"An error has occurred. Please try again later. If the issue persists, please contact support with this Id: 859f43e3-9f0b-44e3-b415-803d3dff998d"

There's nothing to worry about. This issue is from Microsoft side, just try again after some time (like half an hour or an hour); the error will be gone by itself. In case there's some urgent deployment going on do raise a ticket with Microsoft.

D365FO Unspecified error (Exception from HRESULT: 0x80004005 (E_FAIL))

While opening a table browser you may get this error sometimes saying,

"Unspecified error (Exception from HRESULT: 0x80004005 (E_FAIL))"

Even if you build the model is doesn't work.

Solution:

1- Close Visual studio

2- Open your solution and build

3- Try opening again

Remember you can always directly open table browser from you browser through link. For example, you can open custtable with following link in you development environment.

https://usnconeboxax1aos.cloud.onebox.dynamics.com/?mi=SysTableBrowser&prt=initial&limitednav=true&TableName=Custtable&cmp=USMF

in above link if you change name of custtable to any table it will open.

Thanks!
