Exchange Online - Maximum Number of Items Returned in an Address List

[smarties11]

Hi All,

 

Has anyone noticed that recently, Microsoft have appeared to cap the amount of items that are returned in an Address List?

 

For example, we have individual 'teachers of' distributions lists for all students set up (managed by Salamander). We have these in an address list that staff can choose so they don't clog up the GAL or any other lists. Previously all 800-odd of these would be shown in Outlook (desktop) when you chose the address list. Now, it only returns about half of them, stopping at L in the alphabet. You can access those beyond L, but only by using the search - and the search doesn't match any part of the display name, it's a 'starting with' search so in our use case you have to prefix "teachers of" and then student name for the search to return anything. We're going to remove the prefix to address this in the short term.

 

In Outlook (New) or the web version, the behaviour is different in the sense that no items at all are returned. You have to use the search in all cases (and again with the prefix).

 

I just wondered if anyone else had come across this and whether there was a setting buried somewhere to change this behaviour?

 

Thanks :-)
