SYMPTOMS
When you launch or install the Microsoft Exchange Macintosh client, you
may receive the following error message:
Application Unknown has unexpectedly quit because of an error type 1.
CAUSE
A "Type 1" error is a Bus Error, which can be caused by several things such
as extension conflicts, corrupt font, memory conflicts, or system
corruption.
RESOLUTION
WORKAROUND
The following is a list of possible workarounds to this problem:
- Load minimal extensions. Go to the Control Panel Extensions Manager.
Uncheck any unnecessary extensions and restart. You should leave the OLE
and Networking extensions running, and the Microsoft extensions. If this
works, you most likely have an extensions conflict. Add the extensions
back one by one, restarting the computer each time, and test until you
find the conflict. If you do not have Extensions Manager, holding down
the Shift key when you reboot will load without extensions.
- If you are running Microsoft Exchange on a PowerMac, try tuning the
Memory Control Panel. It is recommended to change disk cache size to
1024K, turn on Modern Memory Manager, turn on Virtual Memory, and set the
Virtual Memory to two times "built-in memory" plus 1MB.
Example: If the PowerMac has 16MB of RAM, then set the Virtual Memory
to 33MB.
- Change the "Minimum size" to run the application to 4500K. Highlight the
Microsoft Exchange application file, and choose "Get Info" by holding
down the Apple and I keys. Change the "Minimum size" to 4500K. You can
also try maximizing the size to 4500K.
NOTE: For PowerMacs, if Virtual Memory is turned off, memory requirements
will increase. This will vary by PowerMac model and System version. For
more information, choose "Get Info" on the Microsoft Exchange
application.
- Drag the Fonts folder, located in the System folder, to the desktop.
Restart the Macintosh to create a new Fonts folder. Things will not look
very nice, but this step is for troubleshooting only. If everything works
fine, reload the fonts from the system disk or CD, and/or from other
manufacturer's installation files.
- Reinstall Microsoft Exchange. To perform a "clean" Microsoft Exchange
installation, see the following article.

- Rebuild the desktop. Restart and hold down the Option and Apple keys.
Hold down until prompted to rebuild the desktop, and then click OK.
- Zap the Parameter RAM (PRAM). Restart and hold down the Option+Apple+P+R
keys. Hold down all four keys and the system will act like it is
rebooting. Repeat this three times to make sure the PRAM has been
cleared, and then let the machine boot normally.
- There may be System corruption. Try a new installation of the System
software. Then install Microsoft Exchange (and only Microsoft Exchange)
and test it. To install a new System folder alongside the current System
folder, boot to the install disk or CD, and then hold down the
Command+Shift+K keys when you run the installation.
