We have set up a very simple work flow to get mail-attachments from a shared mailbox and save them into a specific SharePoint folder. There is nothing special configured, just the normal use case.
When processing attachments (PDF files) with sizes smaller than 5MB, the attachment file appears in the SharePoint folder within 1-2 minutes after e-mail fetch is triggered.
When processing attachments (PDF files) with sizes larger than 10MB (we have some attachments with sizes up to 25MB), it lasts up to more than 1 hour, until the file appears after e-mail fetch is triggered.
The Screenshots show the workflow parts and the execution times (successful) for attachment sizes with max. 20MB - there was one mail attachment processed with each trigger. if a process takes a long time (e.g. 2h), all subsequent processes are delayed by this time.
What causes this long processing time, is there a way to solve this or is this a fundamental problem with handling "large" mail attachments (> 10 MB)?
