bradh,
Thank you for your kind offer. What details do you need? Our sys admin, Peter, can provide.
To reiterate:
We are using Exchange '07 and there were no synchronization issues whatseover (neither with prior OS X releases) up until the minute I personally upgraded to Mavericks, with no change whatsoever to Exchange or Mac Mail setup, at which point: a) emails began to appear in my in box much delayed unless the app was reopened, b) email deleted via iOS devices only deletes in Mac Mail when one clicks on it and c) sending attachments frequently cause(d) a can't send with this server error but a second attemp would always work.
The only thing that may have been resolved by the latest release is c). A workaround for a) is setting check for email to every minute from automatically. b) doesn't seem to have a work around and is a bit of an annoyance.
I must say that I spoke with our sys admin just this morning and he told me that he has not read anything so far in this thread that has suggested to him an approach that he has not already tried. But I greatly appreciate your offer of help and we will be pleased to provide whatever info you need.
From my perspective: if Apple had fixed what is obviously a problem (based on my personal experience and many of the 623 messages and nearly 100,000 views on this discusion so far), why wouldn't they announce it in the release notes? The word Exchange has not been once mentioned in any of them. And there is still a link on this page to an article describing the problem and an akward workaround only.
If however, it is simply a matter of requiring a change of setup in Exchange (or Mac Mail) to enable Mavericks compatibility, why wouldn't Apple simply have published such instructions? To replace the article linked on this page, last updated on February 7, that suggests that there is none?
Again, thank you for your kind offer of help!
