Small warning regarding Apple devices and iOS 13. Apparently an old bug from iOS 6 times has returned and is causing trouble again in iOS 13. I warned about the problem here "back then":
With Apple iOS 13, there are also more and more reports of an extreme increase in logs for the mailbox databases. The logs are being written so quickly that storage space is running out and, in the worst case, the databases are being taken offline due to a lack of memory.
Here are two links on this topic:

If the storage space is already running low, the logs can be cleaned up with a fake backup. However, this is only recommended in an acute emergency:
I am currently still analyzing the error, but it looks like iOS 13 is again causing extreme log file growth in connection with Exchange 2016, at least under certain circumstances. However, I cannot say exactly which versions are affected. I would therefore advise caution.
If anyone can confirm the problems, please leave a comment or post it in the forum.
