Someone on another forum [
RE: BES 4.1.x, Exchange 2007 SP1 and OOF] posted that if you use OWA to specify a start and end time range for the Out of Office Assistant, then the problem doesn't occur. I'm testing this at the moment, but feedback from other environments would be useful, and might even help BlackBerry narrow down where the corruption occurs and speed up delivery of a fix.
It's crazy that this isn't listed as a known issue in 4.1 SP5 as it would save everyone time and aggravation.
Does anyone have access to the text of SDR162722 that they can post here?
UPDATE: this workaround did not work for me on Exchange 2007 SP1 using either OWA or Outlook 2007 SP1 to set the OOF with a specified time range.
