it difficult you, because not provide information.
1. guess if exception thrown in ondisconnection method. note there several excel related functions crash excel in case of exception (including onidisconnection).
2. first time create addin, or did worked before [1]?
3. try addin powerpoint , excel (even if not want). experiance same problems? (some ms bugs[4] in word+excel bugs in outlook, in powerpoint).

i try accumulate tips on page:
