#i387 > MSG_PRESENCE error message in Empty Grids, Dynamics AX 2012 CU 12, 11

Hi, While working on Dynamics AX 2012 R3, I got below error (#i387 > MSG_PRESENCE) while opening Grid in and empty.

Solution
just delete all the .AUC files from users/<username>/Appdata/local folder.
this you have to DO for all the users and all the AX client installed.
repeat again, you have delete filed for all users in all the AX clients installed machines.


hope this will help.
