Moderator Note: Hello Sresukum and welcome to IT Knowledge Exchange. When you post a question – you should always mention the platform or software you’re using, as some questions are applicable to several products. There are many calendar applications but unless you state you’re using Outlook 2003, Lotus Notes 7.0.2, etc. other members won’t know. I would add the Tags for you, if I knew what product you were referring to. You want to make your question as easy as possible for fellow members with the needed expertise to answer. To do that, you need to always mention platform, software, version, etc. Thanks.
