Excel email attachment does not show wrapped text in preview

[asadow]

After downloading the attached email, the text is properly wrapped. However if left-clicking the attachment to preview, the text is not wrapped. And if you attach the file manually, the text will wrap in preview.

library(openxlsx2)
library(glue)
library(Microsoft365R)
.data <- structure(
  list(
    bldg = "5", 
    wo_num = "123421", 
    type = "BE", 
    category = "", 
    Description = "I am a description..............................................................................................................................................................................", 
    date = "02-22-24", 
    status = "S", 
    est_time = 1
  ), 
  row.names = c(NA, -1L), 
  class = c("tbl_df", "tbl", "data.frame")
)

wb_backlog <- function(.data) {
  nm <- names(.data)
  letter_desc <- letters[which(nm == "Description")] |> toupper()
  letter_last <- letters[ncol(.data)] |> toupper()
  
  wb_workbook() |> 
    wb_add_worksheet("Sheet1") |> 
    wb_add_data("Sheet1", .data) |> 
    wb_add_cell_style(
      dims = glue("{letter_desc}2:{letter_desc}{nrow(.data) + 1}"),
      wrap_text = "1"
    ) |> 
    wb_set_col_widths(cols = which(nm == "Description"), widths = 75) 
}
wb <- .data |> wb_backlog()
## Text is wrapped
if (interactive()) wb |> wb_open()

tenant <- Sys.getenv("M365_TENANT")
app <- Sys.getenv("M365_APP")
user <- Sys.getenv("M365_USER")
pwd <- Sys.getenv("M365_KEY")

ol <- get_business_outlook(
  tenant = tenant, app = app,
  username = user, password = pwd,
  auth_type = "resource_owner"
)
#> Loading Microsoft Graph login for tenant 'redacted'

file_1 <- tempfile(fileext = ".xlsx")

wb |> wb_save(file_1)

email <- ol$create_email(
  subject = "Email subject",
  to = "<your.email@gmail.com")$
  add_attachment(file_1)

I'm not sure what this is about. Are you saying the file doesn't attach properly?

Something along those lines. The attachment through code has different preview behavior than an attachment through manual means (drag and drop e.g.).
