We are in the middle of an Exchange 2013 migration from 2007 and this is the 2nd time I've encountered this issue. The migrated user cannot open outlook or log into owa. The error that is thrown in owa is below. I cant really find any info on this error. Also, notice the date. No idea where its getting that. We've moved about 7000 users and I've seen this on two of them. I'd appreciate any insight on this. Thanks.
