Research here and elsewhere tells me that In Outlook 2000 with Exchange 5.5, there is no way to globally set auto archive options from the server and auto archiving in Outlook is turned on by default for the sent items folder and is set to auto archive items older than two months.
I have never made changes to these options, there is not anyone else here with the access to make changes.
No ones sent items folder ever auto archived until now (we started using Outlook 2000 with Exchange 5.5 Sept 2001)
Now everyone’s sent items folder is set to auto archive after two months, some have auto archived and some have not (indicating that the two months has gone by for some but not all users)
If this is the default setting, why didn't anyone’s sent items folder ever auto archive until now?
If they were not set this way all along, how could the settings get changed when no one has gone around and done it?
