出现9646错误日志，一般情况下由于打开过多的连接导致的。在Exchange 2003 SP1，对单个邮箱来说，最大的MAPI会话数量为32，如果会话数量超过32的话，您将无法建立新的MAPI会话到您的邮箱。根据我的研究，您可以尝试通过下面的方法来修复：

1、假设您有无线网络和LAN，在相互切换之前，请先关闭Outlook；
2、在Exchange 服务器上设置下面的注册表键值：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\KeepAliveTime
该值的范围为1 到7,200,000 ，建议设置为 300,000 (5 mins)，缺省值为7,200,000 (2 hours)

3、将下面的注册表键值设置为1，
HKEY_LOCAL_MACHINE\SYSTEM\Curre

Solution:

Click Start, click Run, type regedit in the Openbox, and then click OK.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem

If the Maximum Allowed Sessions Per Userentry does not exist, do the following:
On the Edit menu, point to New, and then clickDWORD Value.
Type Maximum Allowed Sessions Per User as the entry name, and then press ENTER.
Right-click the Maximum Allowed Sessions Per User entry, and then click Modify.
Click Decimal, type the value that you want to set in the Value data box, and then click OK.
Exit Registry Editor.
Click Start, click Run, type services.msc in theOpen box, and then click OK.
Click the MSExchange Information Store service, and then click Restart Service.
