When one my customer tried to add a Global Address Book entry to the Contacts folder, the contact is not added. She received the following error message: There is not enough memory to perform the operation.
This problem may occur if the size of the certificate data exceeds 32,768 bytes (32 KB).
Follow the following steps to resolve the issue:
