INFO: IMAPITable::Restrict Returned Rows Limitation in Exchange Address Book

This article has been archived. It is offered "as is" and will no longer be updated.
The Microsoft Exchange Server Address Book has always limited the size ofrestrictions. For systems without Outlook security patch, the default maximum row restriction is 16000 rows for 32-bit clients and 4000 entries for 16-bit clients. For systems with Outlook security patch, the default maximum row restriction is 5000 rows for 32-bit clients and 4000 entries for 16-bit clients. IMAPITable::Restrict() returns MAPI_E_TOO_BIG (0x80040305) if the number of rows in the resulting restriction exceeds respective default maximum limits depending on the client platform and whether the client has Outlook security patch installed.
More information
Although not recommended, there is a way around this default behavior. Therecommended solution is to be more restrictive with your restrictions, asenormous restrictions are unlikely to perform well.

The default maximum row count is modifiable on the client as a profileentry. To adjust this value set the PR_PROFILE_MAX_RESTRICT entry to themaximum count desired. Please see the Edkmdb.h file (in the BackOffice SDK)for details and constants. The following code demonstrates one possible wayto set this property to 20000:
