I work for the state and am required to use the POS known as Groupwise 8.0.
In the past, I have had no problem exporting my calendar into an .ics file and then importing it into my Gmail calendar. However, I am now getting the Error 413 File Too large error.
So, I have tried to figure out a way to reduce the time period of dates that I am exporting. I have found no method to do that in Groupwise.
I have tried to delete and/or archive all old appointments in order to reduce the size of the file. No success.
So, because I am a lowly user, I cannot install any applications on that machine in order to compensate for the POS program that does not have any intelligent exporting functions.
I have setup a new rule in Groupwise that will automatically add new appointments to my gmail calendar. However, that rule does not work retroactively.
