Hi Guys
We have a problem with mailResolveRecipient returning mailReturnFailure!
This is code that is 20 years old has worked consistently forever. Clearly it is something environmental that is occurring but the symptoms are as follows:
1. Some users work other do not same code same functions.
2. The number of users not working is increasing so the disease is spreading like coronvirus.....
Environment is:
Various windows version PCs & through to 10, Outlook Version 2016, Exchange Server 2013. PB Version 12.5, not yet rolled out the PB2017R3 yet.
My question is what exactly does the mailResolveRecipient actually do what calls do, what calls does it make on the MAPI client? If I can understand this we can give that into to the IT support for them to diagnose the problem.
Perhaps someone knows the underlying details or Appeon dev can take a look for me please.
Thanks in advance
David
