Buffer Overflow in ZCS Migration Wizard for Exchange

Hello everyone !

I'm currently moving away from exchange to a zimbra server but when i use the migration tool, with outlook in user mode, i get this message in the logs

Code: Select all

[MIG MIGRATE EEC] ### ERROR ### Output buffer overflow in EncodeInputBuffer() @ MapiUtils.cpp#1559[Util::CStreamingEncoder::EncodeInputBuffer()]


This happens when the migration tool is trying to migrate an email with emails attached to it.

Does this has happened to someone?

Having it just now. The mig tool seems stuck and produces only these error lines

File size? I'm only guessing it has a file size limit base on the error logs.

No, the size errors are different. We've already raised all the MaxSize attibutes to skyrocket values (500MB).
