CDO and daylight savings change in GMT - potential issues next week!

  • Article

Junners reminded me of this, 910268 Meetings are unexpectedly moved one hour ahead in the last week of October in Exchange Server 2003

Typically there are only four Sundays in October so normally this is not a problem, however in certain years there are five and 2006 is one of them. So after next Sunday we may get calls that appointments are 1 hour out, especially from customers using Blackberry. You’ll be pleased to know that the next occurrence of this issue won’t happen until 2010, 2011 and 2016. Also a supported hotfix is now available from Microsoft.

NB: You must install Microsoft Exchange Server 2003 Service Pack 2 (SP2) before you apply the hotfix
