As we can not create object of ThisAddIn class I have used its member by

C#

var addIn=Globals.ThisAddIn;
addIn.membername;

but as var could not be global I have used it in several method.
Now I am getting stackoverflow error
Could this be a cause of stackoverflow?

There are little chances it is the cause of a StackOverflow exception.
Stack overflows usually occur in recursive method calls, where the condition for exiting recursion is not mastered.
Which line of your code does throw the exception?

class Calendars
{
bool isNewAppointment;
string filter1,filter2,syncAppointmentIds;

public Calendars()
{
isNewAppointment = true;
filter1 = string.Empty;
filter2 = string.Empty;
syncAppointmentIds = string.Empty;
}
Configs objectConfig = new Configs();
GetTextFromRecepientsClass objectGetText = new GetTextFromRecepientsClass();
SetSyncCategories objectSetSyncCategories = new SetSyncCategories();
keyValue objContactList = new keyValue();
OlImportance imp = new OlImportance();

the line:
Config objectConfig=new Config() throws exception

Can you post the constructor for the Configs class?

public Configs()
{
string strContactSynchronization_Conflict = string.Empty, strActivitySynchronization_Conflict = string.Empty, strTaskSynchronization_Conflict = string.Empty;
string strOrganisationName = string.Empty, strCompanyName = string.Empty;
string strDefaultCalendar = string.Empty;
}

Calendars objectCalendars = new Calendars();
AppointmentSync objectAppointmentSync = new AppointmentSync();
SetSyncCategories objectSetSyncCategories = new SetSyncCategories();

Well... It might be the reason of stack overflow error, because an addIn refers to "itself" many times.

As Wikipedia[^] states:

Quote:
The most common cause of stack overflow is excessively deep or infinite recursion, in which a function calls itself so many times that the space required to store the variables and information associated with each call is more than can fit on the stack

MSDN[^] says that there are 3 common reasons:

Quote:

A thread uses the entire stack reserved for it. This is often caused by infinite recursion.

A thread cannot extend the stack because the page file is maxed out, and therefore no additional pages can be committed to extend the stack.

A thread cannot extend the stack because the system is within the brief period used to extend the page file.
