We currently run a 2007/2013 hybrid with a few thousand users running mailboxes in 365
All has been ok until the last couple of weeks when we have had a large number of calls to our help desk to report Synchronization Log messages.
All our users will be using cached mode and for those in folder view they are sometimes seeing up to 50 logs an hour where as previously that many over a month. What's even stranger is that some users are reporting these logs are appearing in their deleted items folder as unread items
The only updates we have performed recent are CU7 to our on premise 2013 servers but I cant be sure this is related.
I havent yet heard of any other issues so I'm assuming these are just false positive type logs that dont have any detrimental effect on the end user ?
Any ideas on how we can stop them at least appearing in deleted items ? We have had some success recreating outlook profiles but this isnt viable for several thousand users and I'm not convinced its going to be a long term fix anyway.
