OL97: 16-Bit Outlook Can Only Open One Schedule+ Appt Book
ID: Q143196
|
The information in this article applies to:
-
Microsoft Outlook for Windows 3.x, Exchange Server Edition, version 8.0
SYMPTOMS
You are using Microsoft Outlook for Windows 3.1 together with the 16-bit
Microsoft Exchange Schedule+ Transport DLL installed from the Outlook 8.03
compact disc. You find that you cannot open more than one Microsoft
Schedule+ user's appointment book in the same session. Additionally, once
you close that appointment book, you cannot reopen the Schedule+ user's
appointment book in the same session. Subsequent attempts to open another
Schedule+ appointment book result in the following error:
The schedule file could not be opened. Access is denied.
CAUSE
The 16-bit Exchange Schedule+ Transport DLL, Msoutl.dll is reading the
wrong schedule file from a cached schedule object.
When Schedule+ attempts to open a new calendar it loads drivers one at a
time until it finds a match with the calendar version it is attempting to
view. On the first attempt to view the calendar, Msoutl.dll creates a
schedule object and caches it; if the cached object does not match the
calendar version that Schedule+ is attempting to open, an attempt is made
with another driver. Even though a subsequent driver may be correct for the
calendar version that the user is attempting to open, an error is returned
because the originally cached schedule object is not purged from the cache.
RESOLUTION
To work around this problem, you must quit and restart Schedule+ after
opening each calendar.
To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For more information, please see the following article in the
Microsoft Knowledge Base:

Pack
STATUS
Microsoft has confirmed this to be a problem in Microsoft Outlook for
Windows 3.1x, Version: 8.0. This problem was first corrected in Exchange
Server 5.5 Service Pack 2.
