[horde] [Tickets #14550] Re: Active sync via outlook resulting in memory exhausted

  Thanks for that explaination!

My error looks to the same.
HORDE[21601]: Allowed memory size of 536870912 bytes exhausted (tried  
to allocate 603979776 bytes) [pid 21601 on line 1090 of  
"/usr/share/php/Math/BigInteger.php"]

This is just opening that mailbox mind you all others are fine in outlook.
