User Cannot logon to exchange 5.5

By kevin_j_t ·
A users Exchange Account in SBS was edited by changing her Primary NT logon to that of ANOTHER user so that the other user could get an email message out of her inbox. (Why it was done this way is beyond me!)

Then,within 10 minutes her Primary NT account was changed BACK to her account and all settings applied. At least thats what I can tell, since I didn't do any of this.

PROBLEM: The user can logon to her NT account just fine, but CANNOT log on to Outlook 2000 whatsoever. She gets this error: "UNABLE TO OPEN YOUR DEFAULT E-MAIL FOLDERS. YOU DO NOT HAVE PERMISSION TO LOG ON" .

I logged on to her machine as myself and was able to get emails from my inbox just fine.

My guess is that there is a PERMISSIONS (obviously) setting or bug or snafu somewhere that I'm over looking. I know it can't be a local setting so it either an EXCHANGE issue or User Logon issue.

User Cannot logon to exchange 5.5

By default, permission changes don't happen immediately. Here's an article on why, and how to change this behaviour if you wish.


FORCING RAPID UPDATES
Ever noticed that changes made to the primary NT account on a mailbox
don't take effect right away? The new account can't get into the mailbox, and the old account still has access for up to two hours.

To quote Microsoft, this behavior is "by design." The information store caches reads from the directory, presumably for performance reasons.
The IS reloads this cache every two hours. You can modify this behavior by performing a registry edit.

1. Open Regedt32 and navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem.
2. On the Edit menu, click Add Value.
3. For the value name, enter Mailbox Cache Age Limit.
4. Enter REG_DWORD for the Data type.
5. Enter 1 for Data (type HEX) and click OK.
6. Stop and then restart the information store service.

The "1" instructs the information store to reread the directory cache every minute. Now when you change a primary account, it will take
effect within a minute.

NOTE: Be sure to back up your registry before editing it so you can restore it if something goes awry.
