MAPI_TABLE_TOO_BIG



CAUSE
This problem may occur if there are more than 65,536 mailboxes on the Exchange server because MAPI has a limitation of 65,536 entries in a MAPI table.

After you install this hotfix, you must also add the  registry value. To do this, follow these steps:

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.  Click Start, click Run, type regedit.exe, and then click OK. Locate and then click the following key in the registry:

 On the Edit menu, point to New, and then click DWORD Value. Type GetMailboxTable skip value, and then press ENTER. On the Edit menu, click Modify.</li> In the Base area, click Decimal.</li> Quit Registry Editor.</li></ol>

Note After you add this registry value, the GetMailboxTable function obtains the first 65,536 entries. To obtain entries after the first 65,536 entries (that is, to obtain entries starting at the 65,537 entry), you must set the  registry value to 65,536.
