SYMPTOMS
When you try to reconnect to your Exchange Server mailbox, you may receive the following error message

LDAP Provider

The issue occurs because Lightweight Directory Access Protocol (LDAP) queries Active Directory by using the User32 API CharPrevW function, and this function does not recognize some Thai Unicode vowel characters. The User32 API CharPrevW function may not recognize the following Thai Unicode characters:

0E38

0E39
