We have two administrative assistants with proxy access to various managers' and directors' calendars. After upgrading to GW 8.0.2 over a year ago, they have periodically encountered a problem whereby the proxied calendar shows appointments only up to 30 days into the future -- everything beyond that is blank.
The workaround we found for them is to remove the manager's account from their proxy list and then add it back in. This appears to fix the problem for awhile, but several months later it may happen again.

Has anyone else encountered this error? Any ideas on what to check to help pinpoint what's causing the issue?
