Last week, we have experienced a strange issue. One of the lists has a “peoples and groups” column, the usernames of some of the users didn’t seem to appear even though they are selected the same way as others. After a 3-4 hours of research, I could figure out that the issue is related to permissions and the fix is adding them to the same SharePoint group which has permissions on that library.
Here are the research steps:
1) I have granted those users “contribute” permissions on the JE library and tried uploading the JE and their names seem to appear
2) Next, I have cut-down their permissions and gave them Read-Only permissions on the JE library. It worked even with Read-Only permissions.
3) Next, I have just added them to the Finance_JE_Preparer group under the same role: JE_Preparer. It worked.
I am not sure if this fix actually makes sense but I believe this issue has something to do with the maintenance activity of re-granting the same permissions to the users in question.
Hope this helps…….
