- You create a subsite inside a Microsoft SharePoint Online or Microsoft SharePoint Server 2013 site collection.
- When you create the subsite, you specify a language that has different default regional settings than the regional settings that are used for the parent site collection.
- You add a Microsoft Access app to the subsite, and then you link a list from the parent site collection to the Access app.
- You save the Access app and then open the Access app.
After you receive this error message, the Access app won't open again without error. Additionally, in a SharePoint Server 2013 on-premises scenario, the Unified Logging System (ULS) logs may display the following message:
System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
To avoid this issue, you should create the subsite by using a language that uses the same default regional settings as the parent site collection before you add the Access app to the subsite.
