Hi, we have a business requirement to change the minimum number of characters from 4 to 3 (or even 2) when searching GAL from ActiveSync devices.

I understand how to do this, but I know this limit was put in place to prevent overloading on Exchange so I want to validate that this change will not degrade Exchange performance. We have a 760 mailbox environment so I would imagine there wouldn't be too many GAL lookups performed throughout the day but I need to qualify this assumption.

Is there a way to do this? I can search how many ActiveSync devices there are, but this does not tell me what they are doing. Is there any event log entries when a GAL search is performed on the CAS server? I couldn't see anything when browsing through the event log, perhaps something in IIS that could

Hmm, no one?

Took a leap of faith, with 700 mailboxes no performance impact was noticed.

I have a same problem, Could you please help me how to reduce the searching character to 2 instead of 4.

What I did was to lower the number by 1 each day and monitor the performance impact. With 700 Exchange objects we didn't notice any difference.

Could you please give us the solution the way you did it...

Thanks

You need to change the web.config file...
