I am using Office for Mac 2011. In the outlook, there is no option for inserting a table into the body of the email.

Even if I cut and paste a table from microsoft word onto outlook and vice versa, the alignment and font all changes. It is difficult to make changes in any table in outlook

When we reply to any email also, the font and alignment of the email changes automatically and if you try to modify, it does not allow

When using outlook on windows, you may modify the attachment and save the changes in the attachment only for sending the email. This is not permitted in office for MAC 2011. If you make any changes to the attachment, to save the changes, you have to save the document on the computer. Basically, the changes is made to the original document itself. e.g. if attaching an excel file, if on the windows platform, you can delete worksheet or even make changes, but in the Mac platform, this is not permitted. 

Hope for some concrete solution or else it is difficult to use the outlook on the Office for MAC 2011.
