I installed avast! 4 home on my xppro box (german, sp1a, ol2000).
After the obligate reboot i got a message box
before I login:
German: "Entweder existiert kein Standard-Mail-Client, oder der aktuelle Mail-Client kann dieMessaging-Anfrage nicht erfüllen. Bitte führen Sie Microsoft Outlook aus und legen Sie es als Standard-Mail-Client fest"
Translated this means: "Either there is no standard E-Mail-Client or the actual E-Mail-client cannot handle a messaging request. Please run microsoft outlook and define it as standard e-mail client" (You can find the original text in HKLM\software\clients\mail\prefirtsrun")
Outlook is defined as standard e-mail-client in the registry (HKLM\software\clients\mail(standard)
This message is related to the mapi32.dll (found in the exchange-sdk-doc: "the mapi32 stub library)
What is avast doing with mapi befor a user logs in
After the login everything seems to work fine but the start of outlook is very very very slow
on my 700Mhz PIII without avast outlook starts in less then two seconds. With avast it needs 10 to 20 seconds!!
After this experience I tried to uninstall the outlook/exchange-protection. No way! Setup hangs my hole box with the progress-bars at 0%.... (big red switch required!)
Same behavior when I try to uninstall avast completly.
